BO105 Bölkow

El 16 de febrero de 1967 realizaba su primer vuelo el prototipo V-2 del BO105 (existió un V-1, que montó un rotor principal articulado proveniente del helicóptero Westland Scout, pero en los ensayos iniciales en tierra entró en resonancia de suelo y quedó completamente destrozado).

HISTORIA

El diseño se inició en julio de 1962, la compañía Messerschmitt Bölkow Blohm (proveniente de Messerschmitt AG, conocida por sus míticos cazas fabricados durante la II Guerra Mundial), había estado trabajando en pequeños proyectos de aeronaves de ala rotatoria; dando lugar a los BO102 y BO103.

BO102 (1959): se trató de una especie de “híbrido” que no podía volar, simplemente se elevaba a una altura máxima de 0,6 metros del suelo y estaba sujeto a una base con articulaciones metálicas para evitar que se pudiera desestabilizar y desplazar de su vertical. Este modelo sirvió como plataforma de entrenamiento para los alumnos futuros pilotos militares de helicóptero, contaba con un cockpit monoplaza y estaba impulsado por un motor de pistón con tan solo 40 CV de potencia que le proporcionaba un MTOW de hasta 325 kg.

Se construyeron 18 unidades, contaba con un rotor de una sola pala, fabricada en fibra de vidrio, y un contrapeso en el otro extremo.

BO103 (1961): fue una versión un poco mayor que el modelo anterior, también monoplaza pero éste ya incorporaba un motor de doble pistón y cuatro cilindros, aunque seguía conservando una única pala de similares características. Llegó a conseguir mantenerse en el aire por tiempo inferior a un minuto, pero no se llegó a fabricar más que el único prototipo.

Tanto el BO102 como el BO103 fueron determinantes para el desarrollo de las palas fabricadas en materiales compuestos del Bölkow, además del diseño inconfundible de los rotores rígidos tan característicos de los helicópteros del antiguo fabricante MBB; la cabeza de titanio en forma de estrella de cuatro brazos de los BO105 y BK117, que actualmente siguen en  producción para los EC145 y H145 (con una cabeza lógicamente de mayor dimensión frente al pequeño Bölkow,  puesto que estos helicópteros de la familia BK117 son de un tamaño  superior:  clase de 4 toneladas).

Incluso  aquellos  proyectos  iniciales  sirvieron  como  precursores  de  los  contrapesos pendulares (System Bölkow) que montan en cada una de las palas.

Hay que  mencionar  al BO104,  que  fue  un  proyecto de  helicóptero  biplaza  con  rotor  principal  rígido  y  dos  motores  con  una  potencia  de 120  CV c/u. Éste  no  llegó  a  pasar  de  la fase  de  diseño  ya  que inmediatamente se  sustituyó por el  BO105.

MBB  BO105  Bölkow
Como comentamos, el proyecto  se  inició  en  el  año 1962  a  través  de  la  experiencia en  los  rotores  que  adquirieron  los  ingenieros de MBB a  partir  de  aquellos  pequeños BO102  y BO103  anteriores. El primer prototipo del Bölkow (denominado V-1) montaba  dos  motores  Allison T63  y  el  rotor  articulado (recordamos, del helicóptero británico Westland Scout) que no llegó  a funcionar.

V-2: Exteriormente el segundo prototipo fue bastante parecido a tal y como conocemos al BO105 que lleva operando estos 51 años, variando en motorización, las puertas traseras eran de apertura normal (no deslizantes), y en todas ellas (cockpit y cabina) la ventana abarcaba la totalidad de su estructura, exceptuando lógicamente los marcos. La cúpula de los motores era completamente diferente, ya que tenía sólo dos salidas de escape en vez de las cuatro características, y estaban situadas a ambos lados del fuselaje (a la altura de la unión de la estructura monocasco con la cola).

Con respecto a su planta motriz ha ido recibiendo actualizaciones y se han fabricado diferentes versiones, pero ha mantenido el característico rotor rígido en forma de estrella de cuatro brazos forjado en titanio monolítico.

El prototipo V-2 realizó su primer vuelo el 16 de febrero de 1967 en Ottobrunn (al sureste de la ciudad de Múnich).

El Bölkow ha sido y perdura como el primer helicóptero ligero bimotor de turbina, además del más pequeño. Esto provocó una gran expectación durante su presentación, ya que permitía regresar a base en caso de fallo en uno de sus turboejes, lo que convirtió al BO105 en el multirole ligero perfecto, sobre todo en misiones offshore y operaciones militares.

El tercer prototipo (V-3) montaba dos turboejes MAN 6022 (MAN Turbo GmbH) que le proporcionaban una potencia de 2 x 375 CV. Éste realizó su primer vuelo el 20 de diciembre del mismo año (1967).

El diseño de sus palas en materiales compuestos, una tecnología revolucionaria por aquel entonces, se realizó en conjunto con el fabricante francés Sud Aviation (antesala de la antigua Aérospatiale), que además había montado el rotor rígido del Bölkow en un Alouette II durante el desarrollo de las mismas para probar su comportamiento en vuelo. De esta colaboración entre ambos fabricantes, fusionados desde 1991 en la división Eurocopter (desde el 1 de enero de 2014 Airbus Helicopters), el francés incorporó el concepto de las palas en materiales compuestos al SA340 “Gazelle” (con rotor principal de tripala, y que volaría por primera vez el 7 de abril de ese mismo año, 1967).

Tal vez a raíz de esta colaboración también saldría el  prototipo BO106,  ya  que  la  similitud con  el  SA316/319  Alouette III  en  la  disposición  de  las plazas  (3  delanteras  y  cuatro traseras  en  dos  líneas  de asientos,  gracias  a  un  ensanche  de  cabina  y  cockpit  de  50 cm)  era  la  misma,  pero  este modelo  de  MBB  no  pasó  de  la fase  de  prototipo  (aunque  sí se  llegó  a  construir  una  unidad  que  realizó  su  primer vuelo en  septiembre  de 1973).

El  BO105 con motores Allison 250-C20  no  voló  hasta  el 1  de  mayo  de  1969,  instalados  en  el  cuarto  prototipo  (V4)  y  que  daría  lugar  al  BO105 C,  aunque  MBB  lo  ofrecería en  dos versiones,  con motorización  Allison  250-C18  y  C20 a  partir  de  la  fecha  de  comienzo  en  producción  (más adelante  entraría  la  C20B)...

El Helimer 401 busca a una mujer desaparecida esta madrugada en Riazor

La tripulación del helicóptero de SASEMAR con base en el aeropuerto de Alvedro (A Coruña) busca, desde esta madrugada, a una mujer desaparecida en la playa de Riazor.

El aviso fue recibido por el 112 Galicia poco después de que la joven de 22 años se metiera en el agua y una ola la arrastrara mar adentro (sobre las 4:45 horas). Las condiciones marítimas, debido a la sucesión de borrascas que azotan la CCAA, mantienen a la totalidad de la costa gallega en alerta naranja.

Inmedíatamente se movilizó al Helimer 401 que se mantuvo rastreando la zona a través del faro de búsqueda esclavizado al sistema IR/TV, ya que las condiciones nocturnas -durante las primeras horas- además de la meteorología adversa prácticamente imposibilitan la búsqueda visual ante la inexistencia de cualquier tipo de marcador en el agua.

Además de los medios de la Sociedad de Salvamento y Seguridad Marítima en zona, el H225 y la Salvamar Betelgeuse, están participando en las labores de búsqueda los bomberos de A Coruña con la Unidad Subacuática, la Guardia Civil a través de una de sus embarcaciones y el helicóptero Cuco con base en la misma ciudad, que estos momentos se encuentra cubierta por un BO105 Bölkow, además de la Policía Nacional, Local y otros servicios de emergencia por tierra.

What You May Not Know About Breaking The Sound Barrier

Learn something you might not have known about one of Aviation's most historic days.


On October 14, 1947, history was made when U.S. Air Force Capt. "Chuck" Yeager flew the rocket-powered Bell X-1 to Mach 1.06 (700 mph) at an altitude of 45,000 ft. over Muroc Army Airfield in California. This was the first manned aircraft flight faster than the speed of sound. Seventy years later, the flight still ranks as one of the most significant milestones in aviation history.













  • There were a total of six Bell X-1s built: three first-generation aircraft like Yeager’s, and three second-generation aircraft that were bigger, faster, and higher flying. Of the three first-generation aircraft, Yeager’s - bearing the serial number 46-062 - was the first.

  • The X-1 was built for research purposes. The fuselage was modeled after a .50 caliber bullet. It was powered by a single Reaction Motors XLR-11 four-chamber rocket engine that produced 6,000 pounds of thrust (each chamber produced 1,500 pounds of thrust). The propellants for the engine (water/alcohol mix and liquid oxygen) were carried in two large tanks in the fuselage.

  • A total of eighteen pilots flew the three first-generation Bell X-1s. Air Force pilot “Chuck” Yeager logged the most flights with 34; a Bell test pilot, “Slick” Goodlin, had the second greatest number of flights with 26.

  • The fastest speed achieved by any of the first-generation Bell X-1s was Mach 1.45 (957 mph). Yeager made that flight on March 26, 1948.

  • There were three different wings built and flown on the three first-generation Bell X-1s. Each differed in thickness with the thinnest being the fastest and the one utilized on Yeager’s aircraft.

  • Instead of taking off under their own power, the Bell X-1s had to be carried to launch altitude by a specially-modified Boeing B-29 “mother" plane and dropped. Rocket power is relatively short lived and propellants are consumed in prodigious quantities, thus requiring the X-1s to be carried to launch altitude (usually around 20,000 feet). The X-1’s powered endurance was around five minutes following launch.

  • The X-1 took off under its own power only once during the course of its flight test program. The flight took place on January 5, 1949, again with Yeager at the controls. The aircraft reached an altitude of 23,000 feet before the engine was shut down. After dumping residual fuel, the X-1 glided back to its takeoff spot and landed.

  • Two days before Yeager became the world’s fastest human, he broke two ribs as a result of being thrown from a horse while riding with his wife, Glennis. Knowing he wouldn’t be allowed to fly if his injury was discovered, he visited a doctor off-base to be examined and have his ribs taped. He later used a broom handle to close and latch the X-1’s cockpit hatch since he was unable to reach it without suffering excruciating pain.

  • The Bell X-1 that “Chuck” Yeager used to break the sound barrier was delivered to the Smithsonian Institution on August 6, 1950. It has been on public display there ever since - though it now hangs from the ceiling of the main entrance hall to the Smithsonian’s National Air & Space Museum. It is considered a national treasure.

Flying High in Dubai With The Bell 505

One of the perks of owning a yacht is the ability to access new and exciting places, as long as these places border a waterway. When they don’t, that’s when a helicopter can help you reach unchartered areas. As a premier travel destination that welcomes tourists from all over the world, Dubai is also growing into a yachting hub. The Mediterranean and Caribbean coasts are the typical hotspots for massive boats and yachts to drop their anchor, but Dubai is becoming more and more attractive to this community. The city boasts high – end luxury resorts and a variety of activities from indoor skiing to desert dinner experiences. From oil and gas to engineering and manufacturing, the booming business in this region is drawing more people in from all over the globe.  
Enjoying time on your yacht near the marina and participating in these immersion activities can be made a lot easier with a Bell 505. The Bell 505 packs a big punch in a small frame which will allow you to maximize your travel experiences. With a glass cockpit and an open interior, passengers possess full visibility of their surroundings. For a city as gorgeous as Dubai, with sprawling desert around it, the enhanced visibility is an added bonus.

As a light single aircraft, the Bell 505 is a perfect fit for all sized yachts. It can be used to bring guests arriving at the nearby airport aboard the ship, or even for a last-minute trip to shore to grab extra motor oil, ingredients for a chef or a bottle of champagne. When it comes to the weather in the United Arab Emirates, the hot and dry temperatures don’t stop Bell products from losing their peak performance. Bell's large presence throughout the Middle East proves this fact. Bell 412s have served as the quintessential aircraft being used for offshore oil transport, and the Horizon Flight Academy regularly trains pilots in Bell 407s. With the Bell 505’s recent entry into market, this member of the Bell family is already receiving significant interest in this region.

You can learn more about the small yet luxurious aircraft, perfect for yacht travel, at the Dubai International Boat Show. Also, all Dubai travelers or tourists can also view the Bell 505 in the VIP Terminal of Al Maktoum International Airport until March 7.

Rolls-Royce lean-burn combustion engine starts icing tests

Image caption: ALECSys ice testing is taking place in Manitoba, Canada.
Rolls-Royce’s demonstrator engine, featuring a new lean-burn and low-emissions combustion system for future jet engine programmes, has started icing tests.
The ALECSys (Advanced Low Emissions Combustion System) demonstrator successfully started the tests in Manitoba, Canada, at temperatures of -20C, one month after its first ever test run in Derby.
Technology from the system features in both the Advance3 and the UltraFan®demonstrator engines and also plays an important part in delivering the IntelligentEngine, Rolls-Royce’s vision for the future, which combines pioneering technology and digital capabilities to deliver important benefits for customers.
By constantly monitoring environmental conditions and the pilot’s thrust requirement, ALECSys alters the mixture of fuel and air delivered to various injection points to minimise NOx and other emissions. Tests have so far shown a halving of NOx at cruise, compared to today’s levels.
Andy Geer, Rolls-Royce, Chief Engineer and Head of Technology Programmes, said: “This is another significant step for the ALECSys programme. Our computer models have given us an in-depth understanding of how the system works in extremes of cold and this series of tests will physically validate that. We are confident that this will offer significant benefits for our customers.”
ALECSys, which has received funding from the European Union’s Clean Sky SAGE (Sustainable And Green Engine) programme, is carrying out the tests housed in a Trent 1000 “donor” engine. Other recent Rolls-Royce key technology milestones include:
  • The Advance3 test engine, incorporating the same core architecture that will be used in UltraFan, ran for the first time in November.
  • The Power Gearbox that will enable UltraFan to work efficiently at high bypass ratios reached 70,000hp, an aerospace record, in September.
UltraFan is a geared, scalable design suitable for both widebody and narrowbody aircraft. It is designed to offer 25% fuel efficiency improvement over the first generation of Rolls-Royce Trent engines.

Modernized Lockheed Martin Trident II D5 Missile Test Certifies Submarine for Patrol

SUNNYVALE, Calif.March 28, 2018 /PRNewswire/ -- With the successful launch of two Trident II D5 Life Extension missiles built and upgraded by Lockheed Martin (NYSE: LMT), Navy submarine USS Nebraska demonstrated the readiness of the crew and strategic weapon system. The test, known as Demonstration and Shakedown Operation (DASO) 28, took place in the Pacific Ocean off the coast of southern California March 26.
"In addition to certifying the submarine and crew for patrol, the test launch collected valuable data about the performance of the D5 Life Extension missile configuration," said Eric Scherff, vice president of Navy Strategic Programs at Lockheed Martin. "Instead of warheads, the missiles carried test kits and instrumentation to give us troves of information about flight and subsystem performance. The joint government and industry team will use this data to assess performance and to inform maintenance and sustainment plans for the upgraded Trident missile fleet for decades to come."
The joint government-industry team achieved initial fleet introduction of the D5 Life Extension, or LE, design last year. With modernized electronics and upgraded avionics subsystems, the Trident II D5 LE configuration will be in service with the U.S. Navy and U.K. Royal Navy through the 2040s. The Life Extension program modernized the submarine-launched ballistic missile while maintaining the proven performance of the D5 missile for significantly less than the cost of designing a new missile.
DASO-28 increased the Trident II D5 record to 167 successful test launches since design completion in 1989 – the most reliable test record for a large ballistic missile.

UK Royal Air Force gives green light to Leonardo’s high-tech missile decoy for air combat missions

- Leonardo  has  been  contracted  by  the  RAF  to  supply  its  ‘BriteCloud’  countermeasure  to provide  enhanced  protection  from  advanced  radar-guided  missiles  for  its  Tornado  GR4 aircraft.  The  technology  has  now  been  given  the  go-ahead  for  operational  service 

- Made in Luton,  UK,  BriteCloud  is  the  only  such  technology  in  the  world  which  has  been proven  to  work  successfully  in  trials.  Leonardo  is  Europe’s  leader  in  airborne  electronic warfare,  with  more  systems  in  service  than  any  other  provider 

- The development  of  BriteCloud  is  in  line  with  Leonardo’s  industrial  plan,  which  sees  the company  making  targeted  investments  in  core  technologies  to  support  growth 

Luton,  28  March  2018  –  Leonardo  has  begun  deliveries  of  its  new  ‘BriteCloud’  decoy  to  the  UK’s Royal  Air  Force  for  combat  missions  following  the  Ministry  of  Defence’s  formal  go-ahead  for  the new  technology.  The  drinks-can-sized  countermeasure,  which  protects  fighter  jets  from  modern radar-guided  missiles,  will  be  available  for  use  by  Tornado  GR4  crews  in  the  near  future  The  RAF will  be  the  first  air  force  in  the  world  to  field  this  new  protective  technology.   

The  acceptance  into  service  follows  a  series  of  tests  carried  out  by  the  RAF  in  the  United  States  in June  2017.  These  live  firings  saw  dozens  of  BriteCloud  decoys  launched  from  Tornado  GR4 aircraft  by  the  RAF’s  41  Test  and  Evaluation  Squadron  against  high-tech  radar  guidance  systems. The  tests  produced  a  string  of  successful  results  which  were  then  handed  over  for  in-depth analysis  by  Ministry  of  Defence  scientists  at  the  UK’s  Air  Warfare  Centre  and  the  Defence  Science and  Technology  Laboratory  (DSTL). 

Leonardo  has  worked  since  2012  with  the  UK  MOD  to  develop  active  expendable  decoy technology,  with  the  concept  originating  through  a  project  commissioned  by  DSTL  and  jointly managed  by  Leonardo  and  the  MOD’s  Defence  Equipment  and  Support  (DE&S)  organisation. Leonardo  has  subsequently  invested  significantly  in  its  Luton-based  electronic  warfare  centre  to develop  and  manufacture  the  final  BriteCloud  product.

In  late  2017  the  Ministry  of  Defence  approved  the  technology  for  operations  and  first  deliveries  of the  decoys  by  Leonardo  to  the  RAF  will  take  place  this  month.  The  speed  at  which  BriteCloud  has been  taken  from  the  drawing-board  into  operational  service  is  a  product  of  Leonardo’s  close partnership  with  the  RAF’s  Rapid  Capabilities  Office,  which  was  established  to  get  new technologies  into  the  hands  of  warfighters  more  quickly. 

BriteCloud  packs  a  sophisticated  electronic  radar  jamming  system  into  a  package  just  a  few  inches long.  The  decoy  can  fit  into  a  fighter  aircraft’s  standard  chaff  and  flare  dispenser  and  can  be ejected  at  the  push  of  a  button  if  the  aircraft  is  locked  onto  by  a  modern  radar  guided  missile.  Upon launch,  BriteCloud  instantly  powers  up  and  its  automatic  jammer  produces  a  ‘ghost’  signal  to defeat  an  enemy’s  radar,  making  it  straightforward  to  use  and  able  to  protect  its  host  aircraft  even in  situations  where  traditional  chaff  and  flare  countermeasures  would  be  ineffective.  The technology  is  generically  called  an  ‘Active  Expendable  Decoy’  (EAD);  ‘active’  because  of  the electronic  jammer  and  ‘expendable’  because  the  decoy  is  fired  away  from  the  combat  jet  to  create a  large  ‘miss  distance’  for  an  incoming  missile.

The Qatar Armed Forces NH90 will feature the RTM322-01/9A version. It features a 7% power increase over the baseline RTM322-01/9 variant. This additional power increases mission capabilities in "hot and high" conditions.
Today, 1,100 RTM322 have been delivered worldwide, accumulating over 1.3 million flight-hours.
As part of this agreement, Qatar has also ordered 16 H125 light single-engine helicopters for operation by the its Armed Forces Air Academy. These rotorcraft will also be Safran-powered, by the Arriel 2D .

Airbus Helicopters H160

H160 #3 ©Sthéphane Kervella
(Airbus Helicopters)

Desde que el H160 PT1 despegó por  primera vez en junio de 2015, entre los tres prototipos (#1, #2 y #3) han  superado las 600 horas de vuelo en las que se han ido realizando todos los  ajustes necesarios, tanto sobre toda la  envolvente como respuesta a los mandos y comportamiento de los sistemas de aviónica. Asimismo ya se han desarrollado buena parte de los test necesarios para su certificación bajo condiciones meteorológicas extremas, principalmente en ambientes gélidos con temperaturas bajo cero.

Se espera su salida al mercado y puesta en servicio, comenzando con el Oil & Gas, para el próximo año 2019 (la  línea de montaje final para el H160 en  Marignane ya se encuentra prácticamente lista para comenzar con su producción en serie).

En paralelo se está desarrollando una nueva sección de soporte al cliente a  través de  la  campaña “Operator  Zero”, utilizando para ello los tres prototipos además de todos los medios sobre los que se están realizando las pruebas necesarias para verificar y mejorar el plan de mantenimiento, tarjetas digitales de trabajo, toda la  documentación técnica necesaria y las herramientas específicas.

Además de la primera variante que se certificará y saldrá de cadena de montaje una vez comience su producción, la previsión del fabricante es que la siguiente versión que entre  en servicio sea la EMS.

Los helicópteros H160 estarán  motorizados únicamente por la también compañía francesa Safran  (Turbomeca), no existirán versiones  de este modelo propulsadas por turbinas de otros fabricantes.

Safran Arrano es la denominación de la nueva serie de turboejes pensados para helicópteros monomotor de 2 y 3 toneladas, así como bimotores de 4 a 6 Tons. Sus rangos de potencia oscilan entre los 1.100 y los 1.300 CV (c/u), además poseen el hándicap de una  importante reducción en su consumo,  entre un 10 y un 15% menor (Arrano forma parte del programa Clean Sky). A todo ello se suma que las nuevas turbinas aumentan considerablemente el rendimiento (rango y carga) de los helicópteros de nueva generación, al mismo tiempo que reducen su huella ambiental. Además su diseño minimiza  y facilita el mantenimiento y la sustitución de piezas y/o secciones,  dentro de un tamaño por turboeje de dimensiones más reducidas respecto a otras con sus mismas características. También incorporan  varias innovaciones técnicas, entre las  que se incluye un revolucionario  núcleo termodinámico desarrollado para el demostrador tecnológico Tech 800 (éste fue el resultado de un estudio  de investigación financiado por el  programa Clean Sky de la Comisión  Europea, una asociación de carácter  públicoprivado con la industria  aeroespacial perteneciente a la UE). La  división Safran Helicopter Engines  desarrolló el Tech 800, con 1.100 CV de potencia, en colaboración con treinta y cuatro socios, de los cuales diecisiete fueron PYMES y el resto  universidades y centros de investigación de diez países europeos.

Arrano incorpora un compresor  centrífugo de dos etapas, diseñado  para ofrecer un magnífico rendimiento y fiabilidad. Cuenta con una cámara de combustión de flujo inverso y una  turbina de potencia de una sola etapa. El sistema IGV, compuesto por álabes  de paso variable montados encima del  compresor, mejoran el ciclo  termodinámico del motor durante el  vuelo a velocidad de crucero (lo que  también contribuye a su notable  reducción en el consumo de combustible)...

A King Has Arrived: Sikorsky CH-53 King Stallion Heavy Lift Helicopter Arrives in Germany for International Debut

King Stallion will demonstrate its flight capabilities and maneuverability at ILA Berlin Air Show


HOLZDORF, GermanyMarch 28, 2018 /PRNewswire/ -- A CH-53K heavy lift helicopter built by Sikorsky, a Lockheed Martin company (NYSE: LMT), arrived in Holzdorf, Germany, ahead of its international debut at the ILA Berlin Air Show next month.
This is the first time a King Stallion helicopter has been loaded into a C-17 Globemaster and transported to the base of a European ally.
"We are excited for the opportunity to showcase the capabilities of this all new CH-53K heavy lift helicopter to an international audience. This is the only true heavy lift helicopter in production," said Sikorsky President Dan Schultz.
Sikorsky demonstrated the King Stallion's strategic airlift capability during an exercise at the Sikorsky Development Flight Center in West Palm Beach, Florida, prior to the departure for Germany.
A trained Sikorsky crew partially disassembled the CH-53K helicopter, loaded it into the C-17 cabin and then unloaded the helicopter while representatives from Naval Air Systems Command and the U.S. Marine Corps observed the exercise. As a result, the CH-53K program achieved its Air Transportability Test Loading Activity certification from the U.S. Air Force.
The CH-53K King Stallion test program recently completed the following milestones: maximum weight single-point cargo hook sling load of 36,000 pounds (16,329 kilograms); forward flight speed of 200 knots; 60 degrees angle of bank turns; 12-degree slope landings and takeoffs; external load auto-jettison; and gunfire testing. These milestones come just weeks ahead of Sikorsky delivering the first CH-53K helicopter to the U.S. Marines.
The helicopter will remain at the Holzdorf Air Base, a military airfield operated by the German Air Force (Luftwaffe), until the start of the ILA Berlin Air Show. The CH-53K will showcase its capabilities, maneuverability and advanced fly-by-wire technology during demonstration flights at the air show.
The CH-53K aircraft is an all-new aircraft, using modern intelligent design. The rugged CH-53K is designed to ensure reliability, low maintenance, high availability and enhanced survivability in the most austere and remote forward operating bases.
The CH-53K helicopter is the best choice for completing missions like humanitarian aid, troop transport, casualty evacuation, support of special operations forces, and combat search and rescue. No matter the mission, the aircraft will provide the highest degree of safety for its crew and occupants in all conditions.
