A hatch for a cabin rocket

Abstract

The utility model discloses an execution cabin counter -thrust rocket plug, including plug shell, flat washer, spring washer and screw, the installation location surface of plug shell and execution cabin is an oval plane, and the exposed surface is a cylindrical surface, and there are multiple countersunk slot holes for installing fastening screw at the edge of shell, and the thickness of bottom slot hole is certain. When installing counter -thrust rocket plug on execution cabin, first, place oval plane of plug shell to corresponding installation surface of execution cabin, then put flat washer, spring washer in each countersunk slot hole in turn, and finally, tighten connecting screw. The plug of the utility model can meet the requirement of the execution cabin of installing counter -thrust rocket that the counter -thrust rocket plug shell can be reliably opened when counter -thrust rocket works and can be reliably sealed under high altitude low pressure condition.

Description

Technical Field

[0001] This invention belongs to the field of projectile and rocket technology, specifically relating to a thrust reverser rocket plug for the execution compartment. 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 thrust reverser rocket plug for 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 for an execution compartment, comprising a plug housing, flat washers, spring washers, and screws. The mounting and positioning surface of the plug housing 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, with a fixed thickness at the bottom of the holes. When installing the thrust reverser rocket plug on the execution compartment, first place the elliptical plane of the plug housing 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 and the thickness of the bottom of the countersunk holes need to be determined according to actual usage requirements.

[0008] Beneficial effects

[0009] The plug 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. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of the retro-rocket plug of this utility model. Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0012] Example

[0013] This utility model provides a thrust reverser rocket plug 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 a screw 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, and the bottom hole thickness is constant. 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 sequentially insert the flat washer 2 and the spring washer 3 into each countersunk hole, and finally tighten the connecting screw 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, place the flat washer 2 and spring washer 3 into each countersunk hole in sequence, and finally tighten the connecting screw 4. The plug material and the thickness of the bottom of the countersunk hole need to be determined according to the actual usage requirements.
