Some problems about air air missiles launched by helicopter are studied using neural networks. Firstly, the principle of fire control system about air air missiles launched by helicopter is presented. Secondly, since the armed helicopter model is complex and has less stability, a fuzzy neural network controller (FNNC) is designed. Thirdly, the launch envelop's real time calculation is studied using BP neural networks. Finally, the whole process of designed system is simulated. Result shows that the design requirements are met. In the design of neural network, optimizing algorithm of DFP is used and reference value for real time application in aerial combat is provided.
