Aerodynamic Parameter Identification Based on Dual-Accelerometer

To obtain pivotal aerodynamic parameters when studying missiles, a new method of aerodynamic parameter identification with dual-accelerometer is proposed, its hardware configur-ation and the detailed process are presented. This method can identify the weathercock frequ-ency, angle of attack, over loading, lift coefficient, etc. Actual flight test showed that it could obtain some important aerodynamic parameters according to the use with dual-accelerometer.
