Missile wing expanding wind tunnel test device for box-type vertical launching

Abstract

The invention provides a missile wing expanding wind tunnel test device for box-type vertical launching. The missile wing expanding wind tunnel test device comprises a drive control component, a winch, a steel cable, a guide component, a thrust bearing component, a buffer, a model adapter, a missile model and a simulation launching box. The drive control component and the winch are arranged on the outside of the top wall of a wind tunnel test period. One end of the steel cable fixedly winds the winch, and the other end of the steel cable is connected with the model adapter. The thrust bearing component is fixed on the inner wall of the top wall of the wind tunnel test period through an upper bearing cover. The buffer is arranged on a lower bearing cover. The simulation launching box is mounted on the lower wall of the wind tunnel test period. The bottom of the missile model is provided with the model adapter. The guide component comprises a linear guide rail and a slide block. Two ends of the linear guide rail are respectively fixed on the upper bearing cover and the simulation launching box. The slide block is fixed on the simulation adapter. The missile wing expanding wind tunnel test device is simple in structure, quick to respond, high in reliability and widely applied to the missile wing expanding wind tunnel test for box-type vertical launching.

Description

technical field [0001] The invention relates to a box-type vertical launch missile wing expansion wind tunnel test device, which is applied to the box-type vertical launch missile wing expansion wind tunnel test. Background technique [0002] At present, many air defense missiles and ship-borne missiles are launched vertically in a box. This launching method can not only achieve a 360-degree all-round strike, but also reduce the space occupied by the missiles, increase the number of bombs, and facilitate transfer transportation and daily maintenance. . The wings of many box-launched missiles are folded in the launch box. When the missile is launched, the folded wings are quickly unfolded the moment the missile leaves the launch tube. According to the needs of model development, the test unit has carried out many experiments on the deployment of folding wings, mainly observing the state of folding wings at the moment of deployment, measuring the angular velocity and angular ...

AI Technical Summary

Problems solved by technology

Bottom booster ejection can only simulate the speed and acceleration of the missile out of the box by using a high-speed cylinder. The high-speed cylinder needs to be built to connect the air source, and its response speed is slow, the use and maintenance costs are high, and the technology is difficult

Equipment such as hoists can be used for dragging, but similar equipment on the market can hardly meet the requirements of speed and acceleration, so it is necessary to design electromechanical equipment to provide power
