In the subsonic, transonic and supersonic wind tunnels, the launching test technology of the buried separators in folding rudder separator is studied. In view of the two different folding modes of the Separator rudder surface, two testing techniques are developed for the horizontal folding and vertical folding of the rudder surface, which can ensure the self locking function before and after the rudder surface is unfolded. The folding and unfolding state is not affected by the start impact of the wind tunnel and the turbulence. At the same time, the position of the rudder surface is expanded to achieve the real launch and expansion of the simulated separator. The developed dual angle of view, high brightness optical path system and six degree of freedom image analysis system can obtain the full trajectory image and aerodynamic parameters of the projectile embedded in the aircraft. The test technology can independently adjust the ejection speed and angular velocity of the release material, and can study the influence of different separation conditions on the separation safety. The non-expansion test technology of the rudder surface has completed the wind tunnel test verification under the condition of supersonic velocity and multi-body interference and complex aerodynamic force, which meets the demand of the launch and wind tunnel test research.
