In view of the influence of the folding wing deployment mechanism design on the deployment process, the mathematical model of the wing deployment-deployment mechanism is established. Through the comparison of ADAMS software simulation and gun-launched test, the rotational speed module or torsional spring torque module can be used alone in the design of the deployment mechanism, if the angular velocity of the wing deployment is too large, the friction torque module can be considered to increase, and the aerodynamic torque module needs to cooperate with other modules. The test results show that the design can provide a theoretical reference for the design of the same type of folding wing deployment mechanism.
