Application of high speed slip ring pilot in aero engine

An aero engine is a highly complex and sophisticated thermomechanical engine that provides the power required for aircraft to fly. As the heart of the aircraft, it is known as the "flower of industry", which directly affects the performance, reliability and economy of the aircraft, and is an important embodiment of a country's scientific and technological, industrial and national defense strength. At present, only a few countries in the world can independently develop high-performance aero engines, such as the United States, Russia, the United Kingdom, and France, and the technical threshold is very high.

Compared with the comprehensive technology of aero engines, conductive slip rings are insignificant, but they also play a vital role in the whole equipment, it is at the core of the equipment, and it is the core component that helps the equipment transmit energy and signals. The aircraft belongs to the high-speed flight environment, and the air entering the combustion chamber is pressurized by the stamping action during high-speed flight. It requires conductive slip rings to be able to rotate at high speeds in a high-temperature environment. SPR-ing Optoelectronics has successfully developed a 90,000-rpm high-speed conductive slip ring, which can be used in aero engines.
At present, China is far from the international level in the area of aviation development, and the engine on the fighter plane has not been able to be localized. Why is China's aero engine technology backward? In other words, such a small size fan and turbine in turn have to bear a force of 12.5 tons at all times, and the turbofan engine has to propel the aircraft to fly at twice the speed of sound, and each component has to withstand the extremely harsh high temperature and high pressure test. However, the "industrial crown" of turbofan engines has a variety of new theories, new materials, and new processes, and it is difficult to "know what it is", and it can be said that it cannot be simply copied. Even, in the absence of an operating manual, it is difficult to properly disassemble the turbofan engine. Therefore, the small part of the conductive slip ring alone is facing this serious challenge. What we have to do now is overcome a series of technical challenges. Create a core technology that truly belongs to you. To make further contributions to the country and society as a whole.
