The signals can be used to calculate the real interested parameter-the thrust. Due to this unaccuracy of the calculated thrust, large margins are built to protect aeroengines.

但由于推算的过程不准确，为保证发动机安全运行，在发动机的设计过程中常常保留了较大的裕度。

The adaptive control characteristics of the fuel-richmass flow of the unchoked ramjet are investigated by means of the direct-pipe testing facility- The resultsshow that the unchoked ramjet is superior to that of choke one.

结果表明，非是塞固体火箭冲压发动机是一种性能优良的冲压发动机。

The experimental system of metal fuel/water ramjet was introduced. The unchoked ramjet of metal fuel containing magnesium can burn steadily after once injecting water. In the experiment, the mass flux of water was stable and the pressure of chamber changed similarly with the secondary chamber.

介绍了金属燃料/水冲压发动机试验系统，采用非壅塞式构型实现了镁基金属燃料发动机一次加水后稳定燃烧，试验中进水流量稳定，补燃室与燃烧室压强变化相同。

This event is preceded by another airline's 777 equipped with Rolls-Royce Trent 895 engines, which experienced an uncommanded dual engine rollback while on final approach to London's Heathrow International Airport on January 17, 2008, crashing short of the runway on airport property.

这次事件是继2008.1.17日另外一家777（装备罗尔罗伊斯Trent895发动机）在伦敦希思罗国际机场的最后进近阶段发生了发动机收回，坠毁在碰到头的又一次事件，英国航空事故调查委员会正在调查那次事件。

Oil pump contamination was identified as the reason for an Air France 777 suffering an "uncommanded engine shutdown " on July 1 1998, which caused the plane to be diverted to Tenerife while en route from Sao Paolo to Paris.

航空失事调查局说，目前仍在继续对飞机各系统和发动机进行检查，将进一步检查和分析飞行记录器的信息、飞机各不同系统模块记录的信息，以及可能影响发动机运行的原因。

Research on ignited biogas engine is unsufficient in our country, which leads to serious problems of biogas engine such as high heat load, bad reliability and low efficiency.

国内对火花点火式沼气发动机的研究甚少，生产的沼气发动机在运行中出现热负荷高、可靠性与经济性差的问题。

That's right the Wankle engine started out as a supercharger before someone got the idea to install spark plugs and shooting in gas and call it an engine.

那正确Wankle 当在某人知道之前一台增压器时，发动机开始安装火花塞和把一台发动机在气体和电话里射击给它。

The turboprop engine is very much like the turbojet.

涡轮螺桨发动机与涡轮喷气发动机十分相似。

Maths emulates a result to make clear, apply slant buy scale guides the switch number that brings certain engine switch route to be able to reduce quantity of miss the target and course apparently to accuse engine.

数学仿真结果表明，运用偏置比例导引确定的发动机开关线能够明显地减小脱靶量和轨控发动机的开关次数。

A great number of dynamometer experiments are carried out to investigate the effects of structure characteristics of the injector, configuration of combustion chamber, design of the bypass valve and fuel injection phasing on the performance, emission, fuel consumption of the engine during light load operating conditions. After a final optimization and other practical considerations, the control MAPs for the two-stroke DISI prototype engine are obtained. The torque performance, fuel consumption and emission economy of the engine is tested and compared with those of the original carbureted engine.

并且通过大量的发动机台架试验，分析了喷油相位和喷油器的结构参数、燃烧室形状、旁通孔的大小等参数对发动机低速低负荷工况下的性能、燃油消耗和排放的影响规律；通过最后的优化和实际的考虑，获得了最终的二冲程直喷发动机样机的控制MAP图，试验研究了其动力性、燃油经济性以及排放性能，还做了该样机和原化油器发动机的动力性能、燃油消耗率和排放性能的比较。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
