Aiming at the difficulty and long cycle of R＆D in mathematical modeling and aerodynamic parameters analysis during the process of loitering munition＇s preliminary design and verification, the speediness prototype and integrated modeling method based on X-Plane is proposed. The loitering munition＇s characteristics is analyzed. Meanwhile, the operation mechanisms of various simulation methods are summarized. The principle of X-Plane is also analyzed. Speediness prototype is realized through modeling, which is independent of the mathematical model and aerodynamic parameters. The airfoil and blade design are improved and special controls are implemented, such as mixing, parachute and folding wing. The aircraft design and controller performance are verified by the software in loop （SIL） simulation. Research result indicates that early speediness prototype design and verification of various aircrafts can be realized via the proposed method. It has the advantages of short development cycle and good visual effect. Moreover, it can be significant reference for researchers of aircraft design and control algorithm.
