摘　　要：超音速战斗机的动力学建模仿真十分复杂,源于其研究对象/模型结构的复杂性,及某些模型验证的难度很大,如大迎角气动力学和高超音速空气动力学等,另外还需要建立风、海洋、地景和地形等的自然环境模型等。为此,建立了通用超音速战斗机运动/动力数学模型和气动力/重力模型,用于计算飞行参数和旋转四元数。面向对象技术较符合人类思维方式、程序可重用性高、易于维护的优点,实践证明了面向对象这种设计思想与方法是先进和有效的,在数学模型的基础上,按照面向对象的技术方法提出了的通用战斗机动力学仿真组件。该组件可以精确、全面地反映战斗机的实际飞行的动力学运行特性,并且具有较强的通用性。实例仿真结果表明,该组件适用于工程化领域超音速战斗机飞行仿真软件开发。Simulation of supersonic fighter is very complicated, which is due to the complexity of the object / model structure, and the difficulty of verification of some models, such as high angle aerodynamics and hypersonic aerodynamics. The need to establish the wind, sea, landscape and terrain and other natural environment model. To this end, a generalized supersonic fighter motion / dynamic mathematical model and an aerodynamic / gravity model were developed for the calculation of flight parameters and rotational quaternions. Object - oriented technology is more in line with the human way of thinking, the program reusable high, easy to maintain the advantages of practice has proved that the object - oriented design ideas and methods are advanced and effective, on the basis of mathematical models, in accordance with object -Proposed the general fighter dynamics simulation components. The component can accurately and comprehensively reflect the dynamic performance of the actual flight of the fighter, and has a strong versatility. The simulation results show that this module is suitable for the flight simulation software development of supersonic fighter in engineering field.
