In 1970, researchers in the USSR developed the High-speed Laboratory Railcar (SVL) turbojet train. [6] The SVL was able to reach a speed of 250 kilometres per hour (160 mph). [7] [8] The researchers placed jet engines on an ER22 railcar, normally part of an electric-powered multiple unit train. The SVL had a mass of 54.4 tonnes (including 7.4 ...
In high speed passenger service, the JetTrain would be highly efficient. Due to its lighter weight and modern engine, the JetTrain has greenhouse gas emissions that are 30% lower than a diesel unit operating at the same speeds. [5] The engine is practically silent even at full power: in operation the train is the same volume as the all-electric ...
The Heinkel HeS 011 or Heinkel-Hirth 109-011 (HeS - Heinkel Strahltriebwerke) was an advanced World War II jet engine built by Heinkel-Hirth.It featured a unique compressor arrangement, starting with a low-compression impeller in the intake, followed by a "diagonal" stage similar to a centrifugal compressor, and then a three-stage axial compressor.
The Gulfstream II is a twin-jet swept wing corporate transport powered by two Rolls-Royce Spey turbofan engines and designed to provide high speed and long range capability without sacrificing the airport performance, reliability, and other operational advantages of its predecessor, the turboprop Gulfstream I. Preliminary design of the wing was ...
Ultra long range heavy jets: Jets like these hold enough space to act as flying hotel rooms. With full-size beds and room to stretch out, they can hold up to 17 passengers and travel up to 7,000 ...
M-497 continued to serve for Penn Central after the jet engines were removed until retirement by Conrail in 1977. [ 3 ] [ 4 ] The engines were re-used as X29493, an experimental snow blower . [ 6 ] Like most similar jet engine blowers, it was effective at clearing snow and ice but also tended to dislodge the ballast .
Hush kits can adversely affect the range and performance of the aircraft they are fitted to because of the extra weight. It also reduces engine performance and aerodynamic efficiency. For example, the hush kit fitted to the Gulfstream II adds 106 kilograms (234 lb) to the total airplane weight of 65,500 lb (29,700 kg), causing around a 1.6% ...
Homebuilt aircraft gained in popularity in the U.S. in 1924 with the start of the National Air Races, held in Dayton, Ohio. These races required aircraft with useful loads of 150 lb (68 kg) and engines of 80 cubic inches or less and as a consequence of the class limitations most were amateur-built.
