powered aircraft meaning in English
动力航空器
Examples
- Only in slow - moving , lightweight flying machines , including model planes and pedal - powered aircraft ( such as the english channel - crossing gossamer albatross of 1979 ) , has the use of wing warping continued
只有在速度慢、重量轻的飞行器上还看得到其踪迹，如模型飞机和人力飞机（如1979年横越英吉利海峡的薄纱信天翁号） 。 - During flight of a solar powered aircraft , latitude and direction are changing at all times , therefore the optimal latitude and the optimal direction at different period is developed
太阳能飞机在飞行时，飞行纬度和太阳方位角都在随时发生变化，所以本文着重讨论了每个时段使太阳能飞机获得最大辐射量的纬度和方向(太阳方位角) 。 - 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
本文以滑流干扰的机理为出发点,研究了螺旋桨滑流与飞机机翼、机身、平尾组合体之间的相互影响,推导出滑流引起的飞机升力、阻力和俯仰力矩的变化,给出了滑流干扰对机体气动特性影响的工程估算方法,为研究螺旋桨与飞机部件之间的相互干扰提供了有力的工具,为以螺旋桨发动机为动力的飞机的设计和气动计算提供可靠的依据。
