【Abstract】 With rapid development of neural network (NN) technol og y in recent years, the model for the ramjet missile′s aerodynamic parameter and engine′s thrust and specific impulse are successfully built. Therefore, the de fect of the regressive fitting and interpolation method are overcome. A new tool is presented for the missile popular parameter optimal design and subsystem des ign, and problems in the NN training are analyzed. The improved practical method is given.更多还原
