Description

Technical Field

[0001] The utility model relates to the technical field of aviation engine assembly, in particular to an auxiliary mounting bracket for an aviation engine tail nozzle. Background Art

[0002] The tail nozzle is an important working component in an aircraft engine. It is located at the very end of the engine. Its main function is to continue to expand the high-temperature combustion gas after the turbine to do work, convert the remaining heat energy in the combustion gas into kinetic energy, and eject the combustion gas backwards at high speed, thereby generating forward thrust and providing power to the aircraft.

[0003] At present, the installation of aircraft engine tail nozzles mainly uses the hoisting method. During the entire installation process, a crane or other appropriate equipment is needed to lift the tail nozzle from the ground or other locations, and the lifting point must be located in the structural strength area of ​​the tail nozzle. If the tail nozzle hoisting location is not selected appropriately, it is very likely to bring safety hazards to workers.

[0004] In addition, when hoisting the tail nozzle to the engine, accurate docking of the connection point is crucial. When the connection point is not accurately docked, the assembly method using the hoisting method cannot quickly adjust the connection point of the tail nozzle; this will not only increase production costs, but also lead to unstable assembly quality levels, which will have an adverse impact on the actual engine assembly production.

[0005] Therefore, a technology is urgently needed to solve the technical problems existing in the above-mentioned existing assembly technology. Utility Model Content
