采用计算流体力学的有限体积法和神经网络方法，对矢量喷管的统一数学模型进行了研究，并得到了一种以神经网络描述形式的数学模型。该模型为矢量喷管控制规律和带有推力矢量的飞行／推进系统综合控制的研究提供了一定基础。
By using the finite volume method and neural network method of computational fluid dynamics (CFD), a unified mathematical model of vector nozzle is studied and a mathematical model based on neural network is obtained. The model provides a basis for the research on vector nozzle control law and the integrated control of flight / propulsion system with thrust vector.
