Embodiment Construction
[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0020] In addition, it should be noted that the orientation terms such as left, right, up, down, top, and bottom in the embodiments of the present invention are only relative concepts or refer to the normal use status of th...

The invention relates to the technical field of aircraft systems, and discloses an interstage separation device of aircraft. The interstage separation device comprises a separation cabin body, a cartridge bag assembly and a connecting rod, wherein the separation cabin body is arranged between an aircraft body and an aircraft engine, the cartridge bag assembly is arranged between the aircraft body and the separation cabin body, the connecting rod passes through the separation cabin body in a sealing mode, and the connecting rod comprises a front end part which is connected with the aircraft body, a tail end part which is connected with the separation cabin body and a necking part which is integrally arranged between the front end part and the tail end part and is used for being pulled off during separation. According to the interstage separation device of the aircraft, the aircraft body and the separation cabin body are respectively connected to the front end part and the tail end part of the connecting rod, so that the aircraft body, the separation cabin body and the aircraft engine are stably connected; the necking part which is used for being pulled off during separation is arranged between the front end part and the tail end part of the connecting rod, so that the necking part is pulled off under the thrust of gas generated when the cartridge bag assembly is ignited, and the interstage reliable separation of the aircraft is realized; the device has the advantages of less influence on the aircraft and adjustability of separation impulse.
Description
technical field [0001] The invention relates to the technical field of aircraft systems, in particular to an aircraft interstage separation device. Background technique [0002] For the aircraft system, in order to launch the effective carrier to the predetermined target, it is necessary to unlock and separate the stages and cabins that have completed the scheduled work. The separation and unlocking process is directly related to the success or failure of the aircraft to complete the flight mission. Therefore, the interstage separation device of the aircraft is a key component of the aircraft. The interstage separation device of the aircraft needs to complete two different functions in actual work, that is, to ensure the reliable connection of the two separation parts before separation, to ensure the reliable separation of the two separation parts during separation, and to ensure the separation process. After being neutralized or separated, there will be no harm affecting e...
