Electromagnetically-driven black box throwing mechanism

Abstract

The invention provides an electromagnetically-driven black box throwing mechanism, and the throwing mechanism comprises ejection assemblies, actuating assemblies and a base, wherein the ejection assemblies are arranged in the center of the base, the actuating assemblies are evenly distributed on the periphery of a black box, all the actuating assemblies are arranged on the side of the base, and the actuating assemblies are arranged on the periphery of the black box; the base is installed on the aircraft body, and the ejection assembly is connected with the bottom of the black box; when the aircraft flies safely, the actuating assembly tightly presses and locks the black box; when the aircraft breaks down, the actuating assembly operates and unlocks the black box, and the ejection assemblyacts to eject the black box to enable the black box to be separated from the aircraft body. The electromagnetically-driven black box throwing mechanism is installed on an aircraft body, the black boxis pressed in the safe flight process of an aircraft, and after the aircraft breaks down, the unlocking can be driven under the action of an instruction, and the black box is catapulted to be separated from the aircraft body in advance.

Description

technical field [0001] The invention belongs to the field of aviation technology, in particular to an electromagnetically driven black box throwing mechanism. Background technique [0002] The "black box" is used to record the flight parameters and voice information before the plane crash. After the plane crashes, the information recorded by the black box can be used to trace the cause of the accident. Now, in order to reduce the difficulty of searching, the black box can be thrown away. Separate from the aircraft body in advance, especially in the deep sea environment, to avoid sinking into the seabed with the aircraft. However, most of the existing throwing mechanisms are driven by explosives. Explosives not only have high storage requirements and safety risks, but also the environment Humidity is sensitive, which reduces reliability, and fire attack products have the disadvantages of detonating and polluting the environment. The invention provides an electromagnetically d...

Separate from the aircraft body in advance, especially in the deep sea environment, to avoid sinking into the seabed with the aircraft. However, most of the existing throwing mechanisms are driven by explosives. Explosives not only have high storage requirements and safety risks, but also the environment Humidity is sensitive, which reduces reliability, and fire attack products have the disadvantages of detonating and polluting the environment. The invention provides an electromagnetically driven throwing and separating mechanism, which has a simple structure and small installation space, and can achieve long storage life and safety. High performance, insensitive to ambient humidity and temperature, can improve the reliability of throwing
