目前,在对新设计和使用的战术导弹及其发射系统作飞行试验准备和对试验结果的估评中,都广泛地采用了仿真方法。依据所评价的用于飞行试验的导弹类型或飞行试验的阶段,又采用不同的仿真方法。对于试验发动机用的飞行器,往往采用简易动力学仿真方法,推力装置的性能和气动阻力,是所要验证的主要参数。对于试验无制导飞行器和试验控制系统的飞行器,则需要采用复杂的非线性仿真方法。试验无制导飞行器的目的,是验证发射系统的可行性;而试验控制系统的飞行器的目的,则是验证控制系统性能以及侧向气动力学;实弹飞行试验的目的,是验证控制系统精度。由于存在随机误差源,统计仿真分析用来预测控制精度。为预测控制系统和制导系统的性能,并使飞行器硬件被仿真环节所取代成为可能,则需要采用实时仿真。对飞行试验后的性能进行鉴定,是为说明试验值偏离飞行前预测的原因,并对模型作出改进。要使仿真预测和飞行试验结果之间吻合得很好,只有当模型和飞行条件一致的时候才有可能。
At present, simulation methods are widely used in flight test preparation and evaluation of test results for newly designed and used tactical missiles and their launch systems. Depending on the type of missile being evaluated for flight testing or the flight test phase, different simulation methods are used. For the experimental engine used aircraft, often used simple dynamic simulation method, thrust device performance and aerodynamic resistance, is to verify the main parameters. For aircraft that test unmanned aircraft and test-control systems, sophisticated non-linear simulation methods are required. The purpose of testing a non-guided aircraft is to verify the feasibility of a launch system. The purpose of a pilot-controlled aircraft is to verify control system performance and lateral aerodynamics. The purpose of a live-flight test is to verify the accuracy of the control system. Due to the existence of random error sources, statistical simulation analysis is used to predict the control accuracy. Real-time simulation is needed to predict the performance of the control and guidance systems and to make the aircraft hardware replaced by the simulation. The identification of the performance after the flight test is to explain why the test value deviates from the pre-flight forecast and to improve the model. The good agreement between simulation predictions and flight test results is only possible when the model is in agreement with the flight conditions.
