A cabin reverse rocket plugging structure

Abstract

This utility model discloses a thrust reverser rocket plug structure for the execution compartment, including a plug shell, flat washers, spring washers, and screws. The mounting and positioning surface of the plug shell and the execution compartment is an elliptical plane, and the exposed surface is a cylindrical surface. Multiple countersunk holes for installing fastening screws are distributed along the edge of the shell. Each countersunk hole has a fixed bottom thickness and multiple radial through grooves evenly distributed around its central through hole. When installing the thrust reverser rocket plug on the execution compartment, first place the elliptical plane of the plug shell onto the corresponding mounting surface of the execution compartment, then insert the flat washer and spring washer into each countersunk hole in sequence, and finally tighten the connecting screws. This plug structure can simultaneously meet the requirements of the execution compartment for installing the thrust reverser rocket, ensuring that the thrust reverser rocket plug shell can reliably open during rocket operation and reliably seal under high-altitude, low-pressure conditions.

Description

Technical Field

[0001] This utility model belongs to the field of projectile and rocket technology, specifically relating to a propulsion chamber reverse rocket plug structure. Background Technology

[0002] Currently, in engineering practice, the execution compartment of the retrorockets requires that the retrorockets cover shell be able to be reliably opened when the retrorockets are working, and also be able to reliably seal under high-altitude low-pressure conditions. To this end, a retrorockets cover structure is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a structure for blocking the thrust reverser rocket in the execution module.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] This utility model discloses a thrust reverser rocket plug structure for an execution compartment, comprising a plug shell, flat washers, spring washers, and screws. The mounting and positioning surface of the plug shell and the execution compartment is an elliptical plane, and the exposed surface is a cylindrical surface. Multiple countersunk holes for installing fastening screws are distributed along the edge of the shell. Each countersunk hole has a fixed bottom thickness and multiple radial through grooves evenly distributed around its central through hole. When installing the thrust reverser rocket plug on the execution compartment, first place the elliptical plane of the plug shell onto the corresponding mounting surface of the execution compartment, then sequentially insert the flat washer and spring washer into each countersunk hole, and finally tighten the connecting screws.

[0006] Work process

[0007] When installing the thrust reverser rocket plug on the execution compartment, first place the elliptical plane of the plug shell onto the corresponding mounting surface of the execution compartment. Then, place flat washers and spring washers into each countersunk hole in sequence, and finally tighten the connecting screws. The plug material, the thickness of the bottom of the countersunk hole, and the width and number of through slots must be determined according to actual usage requirements.

[0008] Beneficial effects

[0009] The plug structure of this utility model can simultaneously meet the requirements of the retrorocket's execution compartment. The retrorocket plug shell can reliably open when the retrorocket is working and reliably seal under high-altitude low-pressure conditions, providing a feasible engineering application technical solution.

[0012] Example

[0013] This utility model discloses a thrust reverser rocket plug structure for the execution compartment, such as... Figure 1 As shown, the assembly includes a plug housing 1, a flat washer 2, a spring washer 3, and screws 4. The mounting surface of the plug housing 1 and the execution compartment is an elliptical plane, and the exposed surface is a cylindrical surface. Multiple countersunk holes for installing fastening screws are distributed along the edge of the housing. Each countersunk hole has a fixed bottom thickness and multiple radial through slots are evenly distributed around its central through hole. When installing the retrorockets plug on the execution compartment, first place the elliptical plane of the plug housing 1 onto the corresponding mounting surface of the execution compartment. Then, insert the flat washer 2 and the spring washer 3 into each countersunk hole in sequence, and finally tighten the connecting screws 4.

[0014] Work process

[0015] When installing the thrust reverser rocket plug on the execution compartment, first place the elliptical plane of the plug housing 1 onto the corresponding mounting surface of the execution compartment. Then, insert the flat washer 2 and spring washer 3 into each countersunk hole in sequence, and finally tighten the connecting screw 4. The plug material, the thickness of the bottom of the countersunk hole, and the width and number of the through grooves should be determined according to the actual usage requirements.
