Engineering Estimation and Numerical Simulation of Aerodynamic Characteristics of a Mirco Missile
Microminiaturization is an important direction in the development of air-to-air missiles,and the United States has made some progress in missile miniaturization.The study on aerodynamic characteristics is of great signifi-cance to the control system and trajectory design of micro missiles.The aerodynamic coefficients of a micro missile were simulated by engineering and numerical methods,and the accuracy of the simulation results was analyzed based on the wind tunnel experimental data.The results show that both methods can get the results consistent with the wind tunnel data.The numerical method,with the maximum relative error of 12.42%,is able to get better accuracy com-pared to engineering method(the relative error is less than 27.31%).However,in the initial conceptual design stage of micro-missile,the calculation efficiency of engineering method is higher.
