| 摘 要： | 简要分析总结了螺旋桨式活塞发动机功率特性的相关理论及经验公式，以此为基础，研究了滑移现象和机身对螺旋桨效率的影响问题，提出了一种新的计算螺旋桨式无人机可用功率的方法。结果表明：螺旋桨式无人机若飞行高度保持一定，可用功率、螺旋桨效率与巡航速度成正比；若巡航速度保持一定，可用功率、螺旋桨效率与飞行高度成反比。

| Abstract: | The theory and experimental formulas about power character of propeller-driven piston engine have been briefly interviewed and analyzed. Then, the impact of drift and fuselage on propeller efficiency is investigated. At last, a new method is proposed to calculate the available power of propeller-driven small UAV. The results have shown that if the flight altitude keeps constant, the available power and propeller efficiency are in direct proportion to cruising speed, while if the cruising speed keeps constant, they are in inverse proportion to flight altitude. |
