Design And Performance Analysis For Advanced Air-to-air Missile

In this paper, the aerodynamic, power system (Integral solid du(?)ted rocket) and simple trajectory models were established based on the "meteor" missile. The models can provide technical support for development of the corresponding types of missiles, it also can shorten design cycle time and increase design efficiency.The research focused on the following aspects:1. Improving the performance analytical model of one dimensional solid rocket ramjet engine, validating the feasibility of the models through comparison, computing the power system parameters and analyzing the performance of solid rocket ramjet engine;2. Establishing the mathematical model of aerodynamic computation by using engineering prediction method, especially the accessional drag model of inlet;3. Establishing the trajectory computation model in the horizontal plane, carrying out the trajectory simulation of head-on, pursues, and escaping maneuver. confirming the missile and the computation module performance;The calculation results proved that the aerodynamic model, the power model, the trajectory model and their analysis results in the paper are reasonable. Finally, through comparing of the results and "meteor" data, analyzed the reason of errors, showed the direction for development. It would be of great reference value for development of air-to-air missile propelled by integral solid ducted rocket.
