Analysis of some typical faults of hydraulic system of turbofan jet fuel - supplying governing system
發動機供油調節器液壓系統典型故障分析 -
In arbitrary curvilinear coordinate systems, three dimensional turbulent combustion flow fields of the three kinds of turbofan engine afterburner with the longitudinal heat shield 、 outer cold flow and the jet nozzle are simulated. the three - dimensional body - fitted grids are generated by an elliptical grid generation procedure and zone method
本文在任意曲線坐標系統下對三種帶有縱向隔熱屏、外冷卻通道和尾噴管的渦扇發動機加力燃燒室的三維紊流燃燒流場進行數值模擬。 -
Along with the advent of the highly efficient turbofan jet engine, used today on the majority of commercial aircraft, came a new and challenging problem for maintenance personnel. the repair and replacement of the abradable liner seal, sometimes also known as the fan track.
在大多數商用飛機使用高效率的渦輪風扇噴氣發動機時代到來的同時，飛機維修人員也面臨著新的挑戰，即如何修理和替換發動機上的耐磨損內襯密封條，有時候也被稱為風扇軌道 -
This paper studies the helicopter, the propeller - driven aircraft and the turbofan jet airplane echo modulating feature parameter model and analyses the echo signal feature. it gains the target echo ’ s the cyclical modulation feature by using the complex ar frequency range bispectrum slice. because traditional method in extraction airborne radar ’ s radiant signal feature time has certain insufficiency, this paper proposes the approximate entropy and the norm entropy as the passive feature parameter in the airplane
由於傳統方法等在提取機載雷達輻射源信號特徵的時候存在著一定的不足，本文提出把近似熵和范數熵作為飛機目標識別的無源特徵參數，給出了提取相應特徵熵的演算法，實現對機載雷達輻射源信號的識別，通過和機載雷達類型的匹配，實現對目標的識別。
