The helicopter belonged to the 450 Tactical Helicopter Squadron. Two crew members died while the other two were hospitalized with non-life-threatening injuries. Accident Investigators revealed that the cause of the crash was the crew suffering from ‘spacial disorientation’ causing the aircraft to hit the water. [182]
The Sikorsky Raider X (stylized in all-caps as RAIDER X) (Sikorsky S-102 [1]) is a compound helicopter concept with two coaxial rotors and a single pusher propeller, designed by the Sikorsky Aircraft division of Lockheed Martin for the United States Army Future Attack Reconnaissance Aircraft (FARA) program. The Raider X concept was announced in ...
AAH sought an attack helicopter based on combat experience in Vietnam, with a lower top speed of 145 kn (167 mph; 269 km/h) and twin engines for improved survivability. Lockheed offered the CL-1700, a modified version of the Cheyenne with two engines and omitted the pusher propeller, without success. [44]
Production of a further 17 aircraft was planned [needs update] to begin in 2020. [11] [13] The total FY2015 program cost is $4.718 billion for 23 helicopters, at an average cost of $205M per aircraft. [14] In July 2016, the design passed its Critical Design Review, clearing it for production. [15]
Tandem-rotor helicopters, however, use counter-rotating rotors, with each cancelling out the other's torque. Therefore, all of the power from the engines can be used for lift, whereas a single-rotor helicopter uses some of the engine power to counter the torque. [1] An alternative is to mount two rotors in a coaxial configuration.
Two aircraft were built to prove the tiltrotor design and explore the operational flight envelope for military and civil applications. [ 8 ] [ 9 ] In 1981, using experience gained from the XV-3 and XV-15, Bell and Boeing Helicopters began developing the V-22 Osprey , a twin-turboshaft military tiltrotor aircraft for the U.S. Air Force and the U ...
The Sikorsky S-92 is an American twin-engine medium-lift helicopter built by Sikorsky Aircraft for the civil and military helicopter markets. The S-92 was developed from the Sikorsky S-70 helicopter and has similar parts such as flight control and rotor systems.
