Abstract

The invention discloses a program control box. The program control box comprises a shaft, a switch box, two box covers, a rotor assembly, a screw cap and a shaft sleeve, wherein three pairs of static constant sheets are arranged on the box covers; insulators are arranged inside the box covers; the rotor assembly comprises a rotor, movable contact blocks arranged on the rotor, and insulating blocks arranged among the movable contact blocks; the movable contact blocks are contacted with a pair of corresponding static contact sheets. The program control box can be arranged in a plane seat ejection life-saving system. Through axial transmission, a switch of a plane ejection seat is controlled to be switched off through the static contact sheets and the movable contact blocks, thereby realizing rapid switching among different working states. The program control box has superior technical performance, is light in weight and small in size, has high air tightness, is not influenced by the height change, and can be used at the temperature between 55 DEG C below zero and 70 DEG C.

Description

technical field [0001] The invention relates to supporting products for aircraft, and in particular provides a program control box for controlling aircraft seats to realize ejection. Background technique [0002] In the existing aircraft seat ejection life-saving system, the ejection of the aircraft seat is often affected by external conditions, malfunctions or cannot complete the action in a very short time, resulting in ejection failure, making it impossible for the pilot to escape. Contents of the invention [0003] The object of the present invention is to provide a program control box which can effectively solve the above problems. When a serious accident occurs to the aircraft, the pilot can switch the seat contact electric signal by starting the control box to realize the ejection of the seat to escape. [0004] The technical solution of the present invention is: a program control box, including: shaft 1, switch box 2, two box covers 3, rotor assembly 4, nut 5, sha...
