Problems solved by technology

[0002] When the missile is ejected, the pressure in the initial chamber below the missile increases, and the flexible base that transmits the ejection load effectively transfers part of the ejection load to the ground through its own large deformation capacity under the pressure of the gas, but due to the gap between the base and the ground There are gaps of different sizes, and the existing launch base will cause too much load that cannot be transmitted to the ground during ejection. This part of the additional load of ejection acts on the launch platform, which is a key factor affecting the launch safety of the launch platform and has a negative impact on the launch safety. influences

Embodiment Construction

[0015] Such as figure 1 , 2 As shown, the flexible base of the present invention that transmits the ejection load includes a base plate 11 and a side wall 12, the thickness of the base plate 11 and the side wall 12 is 16mm, and the base plate 11 and the side wall 12 form a barrel shape, such as image 3 As shown, the longitudinal section of the side wall 12 is S-shaped, and the bottom plate 11 and the side wall 12 are all made of twelve layers of nylon / nitrile rubber adhesive tapes. The nitrile rubber sheet is calendered, and the laying angles of twelve layers of nylon / nitrile rubber cloth are 0°, 90°, 45°, -45°, 30°, -30°, 60°, - 60°, 15°, -15°, 75°, 75°, and a layer of nitrile rubber sheet is bonded outside the uppermost layer of adhesive tape and the lowermost layer of adhesive tape.

[0016] The radius of the upper semicircle 121 on the side wall 12 is 26mm, and the radius of the lower semicircle 122 is 41mm.

[0017] Such as Figure 4 As shown, the flexible base for t...

Abstract

The invention provides a flexible base transmitting ejection loads. The flexible base comprises a bottom plate and a side wall. The bottom plate and the side wall form a barrel shape. The longitudinal section of the side wall is of an S shape. The flexible base transmitting the ejection loads has high self-deformation ability, and can meet the requirements for different ground unevenness, and control the ejection loads within the safety range.

Description

technical field [0001] The invention relates to a missile launching device, in particular to a launching base. Background technique [0002] When the missile is ejected, the pressure in the initial chamber below the missile increases, and the flexible base that transmits the ejection load effectively transfers part of the ejection load to the ground through its own large deformation capacity under the pressure of the gas, but due to the gap between the base and the ground There are gaps of different sizes, and the existing launch base will cause too much load that cannot be transmitted to the ground during ejection. This part of the additional load of ejection acts on the launch platform, which is a key factor affecting the launch safety of the launch platform and has a negative impact on the launch safety. influences. Contents of the invention [0003] The object of the present invention is to provide a flexible base for transmitting the ejection load, which has a large ...
