Lift fan is an aircraft configuration in which lifting fans are located in large holes in an otherwise conventional fixed wing [1] or fuselage. It is used for V/STOL operation. The aircraft takes off using the fans to provide lift, then transitions to fixed-wing lift in forward flight.
The Sikorsky S-64 Skycrane has been in service for over five decades. An aerial crane or flying crane is a helicopter used to lift heavy or awkward loads. As aerial cranes, helicopters carry loads connected to long cables or slings in order to place heavy equipment when other methods are not available or economically feasible, or when the job must be accomplished in remote or inaccessible ...
the rear of the F135 engine (nozzle rotated down) that powers the Rolls-Royce LiftSystem. Instead of using separate lift engines, like the Yakovlev Yak-38, or rotating nozzles for engine bypass air, like the Harrier, the "LiftSystem" has a shaft-driven LiftFan, designed by Lockheed Martin and developed by Rolls-Royce, [3] and a thrust vectoring nozzle for the engine exhaust that provides lift ...
This list of accidents and incidents involving commercial aircraft includes notable events that have a corresponding Wikipedia article. Entries in this list involve passenger or cargo aircraft that are operating commercially and meet this list's size criteria—passenger aircraft with a seating capacity of at least 10 passengers, or commercial cargo aircraft of at least 20,000 lb (9,100 kg).
The aircraft was ordered by the U.S. Air Force and delivered from 1981 to 1988. A total of 60 were built. [72] These aircraft are powered exclusively by General Electric CF6 turbofan engines. The KDC-10 was an aerial refueling tanker for the Royal Netherlands Air Force. These were converted from civil airliners (DC-10-30CF) to a similar ...
The Aurora X-65 CRANE is an experimental aircraft that is currently under development. In charge are the Defense Advanced Research Projects Agency (DARPA) and the Boeing subsidiary Aurora Flight Sciences .
The Hiller VZ-1 Pawnee (U.S. Army designation; earlier Army designation: HO-1) is a unique direct-lift rotor aircraft, using contra-rotating ducted fans for lift inside a flying platform upon which the single pilot shifted body weight for directional control.
The aircraft starts from a vertical flight, lifting the aircraft to a high altitude. Then, the aircraft begins to glide, with the total lift less than the weight. With the aid of the forward thrust acceleration, the aircraft quickly gains speed to the aerodynamic speed and then changes the angle of attack to 15° to start an aerodynamic flight.
