Dynamics modeling method for flying qualities evaluation training

针对试飞员飞行品质评价训练的需要,提出了一种飞行动力学建模方法。首先以飞机动力学原理为基础,利用气动、飞行状态和质量特性等参数建立不同飞行品质特性的数学模型;然后,根据需要的飞行品质特性反推相应气动参数,建立飞行动力学模型。仿真结果表明,该方法实现了飞行品质特性连续变化的全量飞行模拟,可为模拟器提供关系匹配的数据,能够满足试飞员飞行品质评价训练需求。

In view of the needs of test pilot flight training qualities evaluations, a flight dynamics modelingmethod was presented. Firstly, based on the principle of aircraft dynamics, the mathematical model ofdifferent flying qualities characteristics were established with aerodynamics, flight state and mass propertyparameters. Then, according to the requirements of flying qualities characteristics, this paper inverselycalculated the corresponding aerodynamic parameters and set up the flight dynamics model. The simulation results show that the method realizes the total simulation of the continuous change of flying qualitiescharacteristics ; it can provide the matching relation data for the simulator and meet the needs of test pilotflight training qualities evaluations.
