电动飞机飞行品质快速评估与验证

Rapid Evaluation and Verification of Flight Qualities of Electric Aircraft

为验证飞行器初步研制阶段使用DATCOM气动估算软件快速估计飞机飞行品质的准确性,以RX1E-A电动飞机为样例,首先使用DATCOM气动估算软件快速计算该机气动参数,并基于该参数评估该机飞行品质。然后使用RX1E-A飞机缩比验证机在风洞试验所得气动数据再次评估该机飞行品质,并结合该机实际飞行试验数据,对基于DATCOM快速评估的RX1E-A电动飞机飞行品质数据进行验证。结果表明基于DATCOM气动估算软件快速评估出的飞机飞行品质与基于风洞试验数据评估飞行品质以及实际飞机飞行试验所得结果相比部分参数虽有一定偏差,但大部分参数偏差较小。因此采用DATCOM气动估算软件在飞机初步设计阶段对其飞行品质进行快速评估是具有一定实用价值的,也为后期开展飞机飞行控制律研究提供参考数据。

In order to verify the accuracy of using DATCOM aerodynamic estimation software to quickly estimate the flying qualities of the aircraft in the initial development stage of the aircraft,taking the RX1E-A Electric aircraft as an example,we first used DATCOM aerodynamic estimation software to quickly calculate the aerodynamic parameters of the aircraft,and evaluate the Flying qualities of the aircraft based on these parameters.Then,we evaluated the flight quality of RXIE-A electric aircraft again using the aerodynamic data obtained from the wind tunnel test of RXIE-A aircraft scale verification aircraft.The quickly evaluated method based on DATCOM was verified in combination with the actual flight test data of the aircraft and the data from wind tunnel test data.The results show that the aircraft flight quality quickly evaluated based on DATCOM aerodynamic estimation sofware has a certain deviation from the flight quality evaluated based on wind tunnel test data and the results of actual aircraft flight test,but most of the parameters have a small deviation.Therefore,using DATCOM aerodynamic estimation software to quickly evaluate its flight quality in the preliminary design stage of the aircraft is of certain practical value,and also provides reference data for the later research on aircraft flight control law.
