[0002] At present, the method of using high-pressure medium to expand and push the load usually places the load in the launch tube, and introduces the high-pressure medium in the rear high-pressure chamber into the low-pressure chamber, using the launch tube as a low-pressure chamber, and the high-pressure medium pushes the load in the launch tube, such as Figure 1 This method has a simple and direct structure and is a relatively easy-to-implement method of ejection load.

[0003] For some loads that are large or cannot be placed in the launch tube, it is not easy to use the above conventional ejection method, and the demand for ejection of large and special-shaped loads is becoming more and more urgent. The ejection method in which the load is placed outside the launch tube is currently the slotted cylinder ejection method that can be found. A slit is opened on the cylinder, and the cylinder is sealed during the movement of the load through a series of complex mechanisms. It is used in the takeoff of aircraft carriers launched by steam catapults. However, the technical threshold of this through-slot slot method is very high. It is quite difficult to keep the ejection cylinder with an opening sealed during operation. Rubber seals, motion mechanisms, service life, etc. are all difficult issues. At present, only the United States has built a slotted cylinder steam catapult for actual combat. Summary of the invention
