The boost engine is an important component for the launch of the aircraft, and it is very important to ensure that the boost engine is accurately installed and positioned, and the installation time is short to avoid a series of problems caused by installation during the launch preparation process. During the installation process of the boost engine, mispositioning, eccentricity during the installation process, and thread necrosis may often occur. In order to solve such problems, especially in view of a series of problems that occur when a large aircraft is installed with a boost engine, it is urgent to research a boost engine auxiliary installation mechanism. SUMMARY

[0003] The technical problem solved by the application is to overcome the shortcomings of the prior art and provide a boost engine auxiliary installation mechanism, which greatly improves the installation efficiency and shortens the installation time while ensuring the installation precision of the boost engine.

[0004] The technical scheme of the application is a boost engine auxiliary installation mechanism, which comprises a left buckle mounting seat, a right buckle mounting seat, a left guide screw, a right guide screw and a positioning block.

[0005] The left buckle mounting seat and the right buckle mounting seat are symmetrical parts, and the left and right buckle mounting seats are connected by two screws on the butt joint surface and are nested into the groove on the tail end of the aircraft through the boss on the end surface, so that the left and right buckle mounting seats do not move along the heading direction and roll.

[0006] The left guide screw and the right guide screw each have a hole protruding out of the aircraft, and one end of each of the left guide screw and the right guide screw passes through the hole on the buckle mounting seat along the heading direction. The other end of each of the left guide screw and the right guide screw has a thread, passes through the positioning block connected to the boost transmitter, and a nut is screwed on the thread that passes through the positioning block. By tightening the nut, the boost engine is pushed towards the heading direction without angular deflection during the process, and finally connected to the tail end of the aircraft.

[0007] The two positioning blocks are arranged on the two sides of the boost engine and connected to the boost engine through fasteners. The positioning blocks correspond to the holes of the left and right buckle mounting seats on the front side and are used to pass through the guide screws from front to back.

[0008] The aircraft tail end is a frame beam skeleton structure, the inner side of the tail end cover is a frame with a groove, and the solid rocket engine tail nozzle is inserted through the groove; the left and right buckle mounting seats are installed on the inner side of the aircraft tail end cover, and are embedded into the groove on the inner side of the aircraft tail end cover through the rear end face bosses, so that the left and right buckle mounting seats are prevented from moving along the heading direction and rolling.

[0009] The left and right guide screws are provided with scales on one side, and are provided with threads on the side with the scales.

[0010] The left and right buckle mounting seats are provided with holes protruding out of the aircraft, and the holes are circular and have one side cut into an arc to form a plane, so that the guide screws are prevented from rotating and are positioned.

[0011] The left and right guide screws are provided with a cylindrical section on the side without threads, and the end of the cylindrical section is a large circular cylinder, and the two ends of the cylindrical section are planes; when the guide screws pass through the holes protruding out of the aircraft, the guide screws are in contact with the left and right buckle mounting seats on the large cylindrical end face and cannot move from front to back along the aircraft, and the planes in the holes cannot rotate, so that the guide screws are matched with the transmission during installation of the boost engine.

[0012] When the left and right guide screws pass through the left and right buckle mounting seats, the side with the scales faces outward, and the two sides are aligned, so that the engine is prevented from being installed at an angle.

[0013] The left and right buckle mounting seats are left-right butt joint structures, and the butt joint surface is provided with a circular groove in the middle to avoid the middle tail nozzle.

[0014] Compared with the prior art, the present application has the following advantages:

[0015] 1. The present application can realize coaxial installation of the boost engine and the aircraft and correct installation angle, and effectively prevents misalignment during installation, eccentricity during installation, and thread necrosis.

[0016] 2. The present application has simple and reliable structure, and is convenient and fast to install and disassemble, and the left and right guide screws are provided with scales, so that the engine can be checked for eccentricity or incorrect angle at any time.

[0017] 3. The present application can adapt to any shape and size of aircraft by changing the structure of the left buckle mounting seat and the positioning block, and has small occupied volume, simple structure, small influence, and high universality. BRIEF DESCRIPTION OF DRAWINGS
