A test device for evaluating the impact of the release of the penetration device on the sub-guided cabin

Abstract

The invention provides a feasible testing device for evaluating the influence of release of a penetration device on a take-off cabin. The testing device comprises a lifting appliance, a releasing mechanism, a control system and a sensor system. The control system controls the releasing mechanism to release the take-off cabin at an assigned height and controls the penetration device to fly away from the take-off cabin at a time sequence. The sensor system can collect the state parameters of the take-off cabin. The lifting appliance is of an H-shaped cross beam structure, the upper ends of the four corners are connected with an external carrier through lifting lugs, the lower ends of the four corners are connected with elastic ropes respectively, the middle of the lifting appliance is connected with a set of rigid ropes through a releasing mechanism, and the other ends of the rigid ropes are connected with the top end of the take-off cabin. The side wall of the take-off cabin is connected with the tail ends of the elastic ropes at the lower ends of the four corners of the H-shaped cross beam structure through the rigid ropes. According to the testing device, the mode that the elasticropes and the rigid ropes are connected in series is adopted, the rigid ropes are used for determining the free falling height of the take-off cabin, the elastic ropes are used for slowing down the falling tendency of the take-off cabin and collecting the take-off cabin, and the purpose of evaluating the influence of release of the penetration device on the take-off cabin can be achieved.

Description

technical field [0001] The invention relates to the technical field of ground verification tests of solid rocket motors, in particular to a test device for evaluating the influence of the release of a penetration device on a sub-guided cabin. Background technique [0002] During the flight of the missile, due to being tracked by the intercepting missile, the main engine is usually turned off and the penetration device is released to ensure the safety of the missile itself. In the process of releasing the penetration device, the flame generated by the penetration device may affect other parts of the sub-guidance compartment when it flies out of the sub-guidance compartment, so tests are needed to assess its safety. [0003] According to the design requirements, during the test process, it is necessary to be able to release the penetration device in the sub-guidance compartment in the specified direction, specified height and specified timing during the free-fall process of th...
