Booster installing and supporting structure with assembling compensating function

Abstract

The invention discloses a booster installing and supporting structure with an assembling compensating function. A first supporting block, a second supporting block, a third supporting block and an elastic device are included. The interiors of the three supporting blocks are integrated and connected through slide rails; the first supporting block and the second supporting block are in bevel contact, and the second supporting block and the third supporting block are in horizontal plane contact. In use, the supporting structures are uniformly distributed in the peripheral direction and adhere tothe inner wall face of a combustion chamber. After a booster is pushed in, the first supporting block retracts in the circle center direction along the slide rail bevel so that the head of the boostercan be tightly held. When the supporting structure bears the radial load, due to friction self locking, the structure is in a stable tight holding state all the time. The remaining travel of a springcan compensate for the axial heat expansion of the booster. The booster installing and supporting structure with the assembling compensating function has the assembling compensating capacity and thethermal expansion compensating capacity, and when a liquid stamping engine plug-in type booster has a diameter deviation and also needs to meet the reloading requirement, the booster installing and supporting structure can serve as the installing and supporting structure of the booster.

Description

technical field [0001] The invention belongs to the technical field of liquid ramjet engines, and is mainly used for the installation and support of plug-in boosters in the combustion chamber of liquid ramjet engines. The plug-in booster is installed and fixed in the liquid ramjet engine for assembly gap compensation, and has a compensation function to adapt to a certain axial thermal expansion. Background technique [0002] A certain type of product uses a solid rocket motor as the booster stage power device, and a certain stage of the solid rocket motor (hereinafter referred to as the booster) is inserted into the combustion chamber of the liquid ramjet engine. Exit from the combustion chamber of the engine to realize the separation from the whole machine product. When the whole product is assembled, the booster uses a special installation vehicle to adjust the axis to align with the axis of the ramjet and push it into the ramjet. Meet the thrust output requirements. ...

AI Technical Summary

Problems solved by technology

[0003] The traditional fixed support structure is generally a fixed support block. The internal support structure of each ramjet combustion chamber can only adapt to the shortcomings of one booster installation, and the support structure needs to be assembled and ground according to the diameter of the booster before installation. To adapt to the gap between the booster and the support structure due to diameter differences after the booster is replaced
