Embodiment Construction

[0011] refer to figure 1 . In the following embodiments, after the silicone rubber is formulated into the bottom layer silicone rubber 4, it is injected into the storage unit casing 1, and the height of the injection bottom layer silicone rubber 4 is controlled at the bottom of the storage unit 2, and the storage unit casing 1 is put into the vacuum box 6 After evacuating the bottom silicone rubber 4 for 5 minutes, restore the pressure of the vacuum box 6 to atmospheric pressure, and let the storage unit shell 1 stand for 30 minutes to cure the bottom silicone rubber 4, and place the storage unit 2 on the cured bottom silicone rubber 4, make the storage unit 2 concentric with the storage unit housing 1, prepare the silicone rubber into a silicone rubber filling body 5, inject the silicone rubber filling body 5 into the storage unit housing 1 where the storage unit 2 is placed, and inject the silicone rubber filling The height of the body 5 is flush with the upper edge of the...

Abstract

The invention discloses a method for potting a flight parameter recorder storage unit with silicone rubber and is intended to provide a potting method that may prevent silicone rubber from producing bubbles during preparing, potting and curing. The invention is implemented through the following technical scheme: injecting silicone rubber into a storage unit shell (1), a height of injected bottom silicone rubber (4) being controlled to a bottom position of a storage unit (2) aerial area, placing in a vacuum box (6), and evacuating the bottom silicone rubber; placing a storage unit on the cured bottom silicone rubber; injecting silicone rubber filler (5) into the storage unit shell in which the storage unit is placed, a height of the injected silicone rubber filler being flush with an upper edge of the storage unit shell, placing the storage unit shell into the vacuum box, evacuating for 5 min, restoring a pressure of the vacuum box to atmospheric pressure, standing the storage unit shell for 30 min so that the silicone rubber filler cures, and fitting a cover plate (3) to the storage unit shell (1) to finish potting.

Description

technical field [0001] The invention relates to a potting method for a storage unit of an anti-shock flight parameter recorder. Especially the potting method of the storage unit of the flight parameter recorder which strengthens the impact resistance. Background technique [0002] The flight parameter recorder is a device for storing flight parameters on an aircraft, commonly known as a "black box". It is one of the special electronic recording devices installed on an aircraft. A device for investigation, maintenance and flight evaluation. Flight parameter recorders generally have the functions of impact resistance, extrusion resistance, fire resistance, corrosion resistance liquid immersion, and seawater immersion resistance. In most air crashes, the only means of survival of the black box is the Crash Survival Memory Unit (CSMU), which stores flight data and audio data. Typically, the black box chassis and other parts of the internals were torn apart. The CSMU is a lar...
