隨著現今嵌入式控制器的性能提升以及感測器的成本降低,有越來越多人投身於四旋翼飛行器的控制器開發。但卻沒有看到關於性能參數分析的文獻。在此篇論文中,將探討四旋翼飛行器的性能參數。首先利用動量法,來分析螺旋槳的空氣動力學現象,根據這個結果來進行不同情況下的性能參數分析,包括推力需求,功率需求,滯空時間,爬升率,下降率,航程,航距。基於這個研究,可以設計出更合乎需求的四旋翼飛行器。 The progress of embedded controller performance and drop of sensors cost, encourage the development of quadrotor UAVs. But, no publication on the research of performance parameters of quadrotors is found. In the thesis, the performance parameters are studied. The momentum method is used to study the aerodynamic performance of rotors. Based on the results, the quadrotor performance parameters studied are thrust required, power required, climb rate, decent rate, range and endurance. The research assures the design of quadrotor UAV which satisfies requirements.
