  1. Whereas many taildraggers can afford to use non - retracting gear with minimal impact on performance, planes with nosewheels almost always require retraction mechanisms to reduce drag

    另一方面，固定式后三點起落架耐沖擊性能較強。而前三點起落架，需要收放式以減小飛行時的阻力。
  2. The planeness and integrality of the flier - plate were ensured effectively by exerting restrictive pressure, controlling heating and cooling rate, lowering welding temperature or reducing welding time as much as possible, etc. theoretical model of creating quasi - isentropic compression via 93w - ofc - tc4 - a1 - mb2 system flier - plate with graded wave impedance was established, and numerical simulation of the impact process was then carried out

    採取施加外部機械力、控制升降溫速率以及盡量降低焊接溫度或減少焊接時間（防止脆性金屬間化合物的過度增長）等措施，確保了焊接接頭的平整性和界面結構的完整性。建立起梯度飛片擊靶的理論模型，對93w - ofc - tc _ 4 - al - mb _ 2系波阻抗梯度飛片的擊靶過程進行了數值模擬計算。
  3. The gear are usually relatively lightweight, and the two main gear can also be easily encased in streamlined fairings to produce low drag in flight

    后三點起落架通常重量都比較輕。兩支主輪子可以配置整流置用來減小飛行中的阻力。
  4. The horizontal and vertical momentum loss caused by the shock of heavy rain in low - level wind shear of thunderstorms on the airframe and wing are analyzed, the water film thickness on the airframe and wings estimated, and the flight resistance resulted from raindrops - striking caused by the roughness of airplane when the heavy rain shocks the airplane is discussed

    摘要分析了雷暴低空風切變中大雨滴沖擊飛機的機身和機翼而引起的水平和垂直動量損失，估算了大雨累計在機身和機翼上的水膜厚度，並討論了因遇到大雨雨滴沖撞而粗糙化的機體所產生的阻力。
  5. Based on the mechanism of slipstream interaction, described in this thesis is firstly the interaction of the propeller slipstream with the wing 、 fuselage and horizontal tail. subsequently, the changes in lift 、 drag and pitching moment are derived, giving an engineering model for the prediction of the increments in the aerodynamic characteristics caused by the interference between the propeller slipstream and the other parts of aircraft. this method offers a powerful means to the calculation of the aerodynamic interaction between the propeller and the aircraft, providing reliable data for the design of and aerodynamic calculation on propeller - powered aircraft

    本文以滑流干擾的機理為出發點，研究了螺旋槳滑流與飛機機翼、機身、平尾組合體之間的相互影響，推導出滑流引起的飛機升力、阻力和俯仰力矩的變化，給出了滑流干擾對機體氣動特性影響的工程估算方法，為研究螺旋槳與飛機部件之間的相互干擾提供了有力的工具，為以螺旋槳發動機為動力的飛機的設計和氣動計算提供可靠的依據。
  6. Air in the middle ear can usually escape without problems but as the aircraft descends and the pressure is increased, the relatively lower pressure in the tube tends to keep it collapsed and result in negative pressure in the middle ear, causing discomfort or pain

    一般情況下，中耳內的空氣可以毫無阻礙地泄出。但當飛機下降氣壓加大時，在耳咽管中的較低氣壓將導致它關閉，並在中耳內產生壓力而引起不適或疼痛。
