Abstract: A comprehensive analysis method, which takes various factors into consideration, is proposed for the compatibility of the armed helicopter and air-to-ground missile (AGM). The influences of the rotor down-wash flow and the flight speed of helicopter on missile trajectory, the relative position relationship between missile trajectory and helicopter during missile launching, and the influence of engine jet flow on the helicopter are comprehensively analyzed. The proposed method perfects the analysis system for the compatibility of armed helicopter and AGM, providing technical support for the compatibility design and the selection of attacking conditions. The analysis results demonstrate that the increased flight speed of helicopter during attack, the reasonable initial ballistic design and the reduced engine jets can improve the compatibility of armed helicopter and AGMs. Simulated and real flight data have verified the effectiveness of the proposed method.
