Airspace engine protective cover

Abstract

The invention discloses an airspace engine protective cover. The airspace engine protective cover comprises a protective cover body; a lug of the protective cover body is movably connected with an internal hexagonal screw; a shaft elastic retainer ring, a spring and a flat gasket are arranged between the internal hexagonal screw and the lug in sequence from top to bottom; the upper end of the spring and the shaft elastic retainer ring are connected through welding; the lower end of the spring and the flat gasket are connected through welding; and the outer side of the shaft elastic retainer ring is connected with the lug through a steel wire or a thin spring. One end of the steel wire or the thin spring is connected with one side of the shaft elastic retainer ring through welding, and the other end is connected with the lug through welding. The protective cover adopts an integral structure of a fastening piece and the protective cover body to solve the problem of missing or falling of the fastening piece in the disassembly process of a traditional engine protective cover; and the operation step of dismounting the engine protective cover is simplified.

Description

technical field [0001] The invention relates to the field of spacecraft components, in particular to a protective cover for an aerospace engine. Background technique [0002] At present, during the general assembly and general inspection of the spacecraft engine on the ground, it is necessary to repeatedly disassemble and assemble the engine protective cover. During the disassembly and assembly of the traditional engine protective cover, it is faced with the disassembly and assembly of fasteners. In the actual operation process, fastening often occurs. In the case of missing or falling parts, serious cases will cause damage to the equipment on the spacecraft. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a protective cover for an aerospace engine, which is a protective cover integrated with the fastener and the protective cover body, which avoids the situation that the fastener is missed or dropp...
