Abstract

The invention relates to a fragile cover locking structure suitable for a high-pressure gas ejection test device, and belongs to the technical field of launching. The fragile cover locking structure suitable for the high-pressure gas ejection test device is simple in structure and reliable in work, a fragile cover body which flies out can be effectively locked, and a fragile cover body structure is prevented from impacting or even damaging an object to be ejected; and a windward side of a locking rod is subjected to low-resistance designing, the fragile cover body is effectively locked, and meanwhile, smooth flow of high-pressure gas in the locking structure is not hindered.

Description

technical field [0001] The invention belongs to the technical field of launch, and in particular relates to a stop structure for a fragile cover suitable for a high-pressure gas ejection test device. Background technique [0002] In the high-pressure gas ejection test device, after the high-pressure gas storage chamber is inflated by an external air source, the pressure of the high-pressure gas storage chamber increases, and when a certain pressure value is reached, the fragile cover between the high-pressure gas storage chamber and the low-pressure chamber is automatically broken. The high-pressure gas is released into the low-pressure chamber, and the moving object moves under the action of the high-pressure gas, so as to achieve the purpose of giving the ejected object a certain speed. After the fragile cover is broken, its body structure will move upward at high speed under the action of high-pressure gas, which may hit the ejected object or even cause damage to the ejec...
