Context: A jet engine is a reaction engine discharging a fast-moving jet that generates thrust by jet propulsion. This broad definition includes airbreathing jet engine(turbojets, turbofans, ramjets, and pulse jets) and non-airbreathing jet engines (such as rocket engines). In general, jet engines are combustion engines., Flight training is a course of study used when learning to pilot an aircraft. The overall purpose of primary and intermediate flight training is the acquisition and honing of basic airmanship skills., The General Electric/Allison J33 was a development of the General Electric J31, enlarged to produce significantly greater thrust, starting at and ending at with an additional low-altitude boost to with water-alcohol injection., The Rolls-Royce RB.37 Derwent is a 1940s British centrifugal compressor turbojet engine, the second Rolls-Royce jet engine to enter production. Essentially an improved version of the Rolls-Royce Welland, itself a renamed version of Frank Whittle's Power Jets W.2B, Rolls inherited the Derwent design from Rover when they took over their jet engine development in 1943. Performance over the Welland was somewhat increased and reliability dramatically improved, making the Derwent the chosen engine for the Gloster Meteor and many other post-World War II British jet designs., Canadair Ltd. was a civil and military aircraft manufacturer in Canada. It was a subsidiary of other aircraft manufacturers, then a nationalized corporation until privatized in 1986, and became the core of Bombardier Aerospace., The Rolls-Royce RB.41 Nene was a 1940s British centrifugal compressor turbojet engine. The Nene was a complete redesign, rather than a scaled-up Rolls-Royce Derwent with a design target of 5,000 lbf, making it the most powerful engine of its era. It was Rolls-Royce's third jet engine to enter production, and first ran less than 6 months from the start of design. It was named after the River Nene in keeping with the company's tradition of naming its early jet engines after rivers., TurboJET is the brand name for the operations of the Hong Kong-headquartered Shun Tak-China Travel Ship Management Limited, which was established from the joint venture between Shun Tak Holdings Limited and China Travel International Investment Hong Kong Limited in July 1999. It operates hydrofoil ferry services in southern China., The Canadair CT - 133 Silver Star ( company model number CL - 30 ) was the Canadian license - built version of the Lockheed T - 33 Shooting Star jet trainer aircraft , in service from the 1950s to 2005 . The Canadian version was powered by the Rolls - Royce Nene 10 turbojet , whereas the Lockheed production used the Allison J33 ., A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by jet engines (jet propulsion)., A jet trainer is a jet aircraft for use as a trainer, whether for basic or advanced flight training. Jet trainers are either custom designs or modifications of existing aircraft. With the introduction of military jet-powered aircraft towards the end of the second world war it became a requirement to train pilots in the handling of such aircraft., The General Electric J31 was the first jet engine to be mass-produced in the United States. , Subject: canadair ct-133 silver star, Relation: use, Options: (A) combustion (B) engine (C) flight training (D) jet trainer (E) mass (F) military (G) propulsion (H) trainer (I) travel (J) war
