Abstract

The invention provides an electromagnetically driven black box throwing mechanism, which includes an ejection assembly, an actuation assembly and a base, the ejection assembly is arranged at the center of the base, and at least two groups of the actuation assemblies are evenly distributed Around the black box, all actuating components are arranged on the side of the base, the base is installed on the aircraft body, and the ejection component is connected to the bottom of the black box. When the aircraft is flying safely, the actuating components press Tightly lock the black box. When the plane crashes, the actuating component operates to unlock the black box. At the same time, the ejection component moves to eject the black box to separate the black box from the aircraft body. An electromagnetically driven black box throwing mechanism according to the present invention is installed on the aircraft body to press the black box tightly during the safe flight of the aircraft. Perform ejection to separate it 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...
