The Voith Schneider propeller was originally a design for a hydro-electric turbine. [2] Its Austrian inventor, Ernst Schneider, had a chance meeting on a train with a manager at Voith's subsidiary St. Pölten works; this led to the turbine being investigated by Voith's engineers, who discovered that although it was no more efficient than other water turbines, Schneider's design worked well as ...
Landing gear extenders are devices used on conventional or tailwheel-equipped aircraft. They move the wheels forward of the landing gear leg by 2-3 inches (5–8 cm). [ 1 ]
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 ...
The range-extender option costs an additional US$3,850 in the United States, [27] an additional €4,710 (~ US$6,300) in France, [28] and €4,490 (~ US$6,000) in the Netherlands. [29] The range-extender option of the BMW i3 was designed to meet the CARB regulation for an auxiliary power unit (APU) called REx.
The Mk 57 Peripheral Vertical Launch System (PVLS) used on the Zumwalt-class destroyers is composed of much larger VLS cells capable of venting much larger volume and mass of exhaust gasses (mass flow rate), but is an evolution of the smaller unarmored Mk 56 VLS. The Mk 57 PVLS are designed to be installed on the ship periphery with armor on ...
The McDonnell Douglas KC-10 Extender is an American tanker and cargo aircraft that was operated by the United States Air Force (USAF) from 1981 to 2024. A military version of the three-engine DC-10 airliner, the KC-10 was developed from the Advanced Tanker Cargo Aircraft Program .
Reliability is a high priority in range safety systems, with extensive emphasis on redundancy and pre-launch testing. Range safety transmitters operate continuously at very high power levels to ensure a substantial link margin. The signal levels seen by the range safety receivers are checked before launch and monitored throughout flight to ...
The Avenger Air Defense System, designated AN/TWQ-1 under the Joint Electronics Type Designation System, is an American self-propelled surface-to-air missile system which provides mobile, short-range air defense protection for ground units against cruise missiles, unmanned aerial vehicles, low-flying fixed-wing aircraft, and helicopters.
