Mechanically redundant rocket fairing air conditioning connector auto-ejection device

The automatic disconnection device for the air conditioning connector of the rocket fairing, which is mechanically redundant, uses electric push rods and electric locking separation mechanisms to achieve automatic separation of the air conditioning inlet duct and connector from the fairing. This solves the problem of cumbersome manual operation and improves the efficiency and reliability of the rocket launch process.

Abstract

The application relates to the field of aerospace technology, in particular to a mechanical-redundant rocket fairing air conditioner connector automatic shedding device, which comprises an electric push rod, an electric push rod connecting assembly, a steel wire rope, an electric push rod support frame, an electrical locking and separating mechanism and a connector main body; the fixed rod of the electric push rod is supported to the upper end of the electric push rod support frame, the lower end of the electric push rod support is fixed to a launching frame, the front end of the movable rod of the electric push rod is fixed to the rear end of the steel wire rope, the front end of the steel wire rope is fixed to the rear end of the electric push rod connecting assembly, and the front end of the electric push rod connecting assembly is connected to the rear end of the connector main body; the electrical locking and separating mechanism is arranged on the connector main body, the front end of the electrical locking and separating mechanism extends into a plug-in hole of a rocket-mounted flange, and the front end of the electrical locking and separating mechanism can be retracted backward to be separated from the plug-in hole of the rocket-mounted flange. The application can separate the air conditioner air inlet pipe and the connector from the fairing simply and does not easily delay the launching process.
