The invention provides a trajectory capture test
system for simultaneous separation
simulation of double external stores, and belongs to the field of high-speed wind tunnel test technology and
aircraft flight mechanics. The trajectory capture test
system comprises a half-arm
attack angle mechanism installed on a wind tunnel test section, and an aerial
carrier model is fixedly connected with the half-arm
attack angle mechanism through an aerial carrier supporting rod; a
missile-loaded base is connected with the wall surface of the wind tunnel test section through a vertical movement mechanism, parallel bottom plates are connected with the
missile-loaded base through rotating shafts, three-degree-of-freedom parallel mechanisms are installed on the parallel bottom plates respectively, the other ends of the three-degree-of-freedom parallel mechanisms are connected with a movable platform, and a rolling driving mechanism is arranged in the movable platform; and the movable platform is connected with
missile-loaded balances and missile-loaded models through missile-loaded support rods. According to the invention, the two missile-loaded balances are used for respectively measuring the
aerodynamic force and torque applied to the missile-loaded models, the motion
modes of the two missile-loaded models are inversely solved, the motion of each driving device is controlled, the multi-degree-of-freedom position and attitude change of the two missile-loaded models is realized in a wind tunnel test section, and the
simulation of the motion trajectory of the double-external store model is realized.
