Boeing's rivals, McDonnell Douglas and Lockheed, were working on wide-body three-engine "tri-jets", which were significantly smaller than the proposed 747. Many airlines wondered if the 747 would prove too large for an average long distance flight and instead invested in tri-...
波音747-400装有5个发动机,其中4个是主发动机(engine,ENG),1个是辅助动力系统(auxiliary power unit,APU)。波音747-400的主发动机均为涡轮风扇发动机。波音747-400的主发动机有三种可选,分别是通用电气航空的CF6-80C2B5F,普惠的PW4062和罗尔斯罗伊斯的RB211-524H。下面以通用电气航空的CF6-80C2B5F型发动机为例...

Control of the airplane began to quickly deteriorate and the only control left was to vary the thrust on the four turbofan engines. The flight crew began an emergency descent and declared an emergency. For the next 32 minutes, JA8119 flew in large uncontrolled arcs. The 747 rolled into banks...
A thrust reverser suitable for reversing the flow direction of the fan air of a fan jet engine is disclosed. The thrust reverser comprises a cascade section and a fan duct blocker section. The cascade
The airliner's first fatal crash, Lauda Air Flight 004, occurred near Bangkok on May 26, 1991, following the in-flight deployment of the left engine thrust reverser on a 767-300ER. None of the 223 aboard survived. As a result of this accident, all 767 thrust reversers were deactivated ...
Four engines, each producing 41,000 pounds of thrust, would be required to get the 747 airborne, and as the airframe design came closer to being finalized, Pratt was way behind the power curve. Engine development and production proceeded so slowly that the entire project threatened to sink ...

Rolls‐Royce RB.211 power for the Boeing 747ROLLS‐ROYCE has been working with Boeing since late 1973 on the development of a version of the Boeing 747 airliner with RB211 engines. It will be powered by the 50 000 lb thrust RB211–524 engine. Production‐standard RB211–524s are ...
high bypass ratio turbofan jet engine to power a wide-body airliner, the JT9D turbofan jet engine provided 235,700 N (53,000 lb) of thrust. Each engine weighed 4,153 kg (9,155 lbs) by itself. The engines were used for years on many versions of the Boeing 747, and 767 as well as...
