AI Technical Summary

Problems solved by technology

Even if these components are installed on the rotor system for balance, it will bring new problems: after the rotor system is balanced, it needs to be disassembled to assemble the whole turbojet engine
Once the rotor system has been disassembled, there is no guarantee that the rotor system will be reassembled in the same balance as it was when it was tested
It can be seen that the traditional balance method is difficult to ensure the balance of the rotor system

Description

technical field [0001] The invention relates to the field of a micro-turbojet engine, in particular to a detection system and method for the overall dynamic balance of a micro-turbojet engine. Background technique [0002] The micro-turbojet engine is an emerging field of propulsion and energy system research, which has the advantages of small size, light weight, high thrust-to-weight ratio, and low cost. Compared with conventional aero turbine engines, the thrust-to-weight ratio of microturbine engines has greater development space and application prospects. At present, it is widely used in small aircraft such as cruise missiles, unmanned aerial vehicles, etc., as its power propulsion device. In addition, micro-turbojet engines also have broad prospects in important fields such as meteorological monitoring and forest warning. With the continuous development of science and technology and the deepening of people's research on micro-turbojet engines, micro-turbojet engines w...
