A cold emitter sealing cover

Abstract

The invention discloses a cold launcher sealing cover installed on a flange of an emitting barrel opening of a cold launcher. At least two bearing platforms are arranged on the outer side face of an opening of a ball-coronary-shaped barrel cover. One bearing platform is a hinge connector which is located at the lowest end of the ball-coronary-shaped barrel cover. The other bearing platforms are connectors. The connectors are used for detachably installing the ball-coronary-shaped barrel cover to the flange. The hinge connectors are used for hinging the ball-coronary-shaped barrel cover to the flange. The cold launcher sealing cover is designed in a ball coronary shape and hinged to the launcher barrel flange, and can be freely opened after constraint is removed without bursting, thereby being reused; in addition, high-wave-transmissivity glass reinforced plastic inner and outer skin is adopted for the sealing cover, so that the sealing cover has the good wave transmissivity; the space between the inner skin and the outer skin is filled with polyurethane foam, so that the sealing cover has the good heat preservation performance, and the wave transmissivity of the sealing cover is not affected.

Description

technical field [0001] The invention relates to the technical field of cold launch, in particular to a sealing structure for a cold launcher. Background technique [0002] The cold launcher sealing cover is the key equipment of the cylindrical cold launching device. It forms a closed space together with the launching tube to protect the missile during the process of mobile transportation, standby and launch preparation. It plays the role of rainproof, sealing, and heat preservation. The cover, among which the telemetry sealing cover used for the telemetry test is also required to have good wave-transmitting performance. [0003] The telemetry sealing cover often needs to be used multiple times in the development and testing of the weapon system. It is required to have sufficient rigidity under the design load and to be easy to connect and lock. It is required to have low thermal conductivity under the long-term standby condition before entering the launch process. coefficie...

AI Technical Summary

Problems solved by technology

[0004] At present, domestic sealing caps are mainly fragile caps, which are broken by missiles during the occurrence process and then launched. They are used once in the launch test and cannot be reused. Because the sealing cap needs to have fragile properties, it generally needs to be placed on the outside of it. Add a metal protective cover to prevent the fragile cover from being broken and opened under non-design conditions

This type of fragile cover is inconvenient to use, cannot be reused, and does not have wave-transmitting performance, so it cannot guarantee that the internal signal of the transmitting device can be accurately locked, and the heat preservation performance is also poor
