低空航路线形设计要素对飞行器能耗的影响分析OA

To guide the design of energy-efficient low-altitude routes,this paper proposes a methodological framework for calculating the operating energy consumption of low-altitude routes during design phase.This framework accounts for the impact of low-altitude route design elements on aircraft operating speeds.Further-more,taking multi-rotor UAVs as an example,the framework was used to analyze the influence of design ele-ments and their combinations within route units on the operating energy consumption of UAVs.The results in-dicate that route length,horizontal curve radius,slope angle,vertical curve radius,and the tangent angles at the start and end points of the vertical curve are the primary design elements affecting energy consumption.Fi-nally,based on calculation results,operating energy consumption assessment formulas for low-altitude routes were regressed,with the design elements as independent variables.The regression formula demonstrates high fitting accuracy.
