자유진동기법을 이용한 공대지 미사일의 동안정성에 관한 연구
A Study on the Dynamic Stability of Air-to-Ground Missile Using the Free Vibration Technique
초록
A dynamic stability test was performed to determine dynamic stability derivatives for the pure pitching motion of air-to-ground missile model in the low speed wind tunnel. The free vibration technique was employed to acquire oscillation characteristics of the model for damping coefficients. Damping coefficients are obtained by the method of logarithmic decrement. Results show good damping effects and stability capability at Mach numbers 0.1 and 0.2, with the angle of attack ranging from -15 to +20 degrees.
