China 650 kg thrust class turbofan engine with independent intellectual property rights available
CNS, Beijing, July 1 (reporters Zhang Tao and Zhang Su)-1st from the China Aerospace Science and industry Corporation that, developed by the Aerospace Division of hospitals-31 China's first independent intellectual property rights of 650 kg thrust class turbofan engine. The engine for future civilian drones and small jets to provide reliable power.
The development team, this is the first volume of 650 kg thrust level, dual-rotor Turbo-fan engines, with independent intellectual property rights, apply to long endurance, a wide range of civilian small aircraft.
It is reported that the engine design uses a high efficiency front swept fan, axial flow + combination of oblique flow compressor, high and low pressure turbine expansion channel integration design, electric fuel lubricating oil pump, generator built a number of key technologies, and advanced electrical, control and health management system, has the characteristics of high performance, compact, and has reached the domestic leading level in small engines.
Design team after more than 10 years, has completed the engine's design, manufacture, production, as well as a large number of components, the whole test, the performance meets the design requirements and machine durability test is carried out in the near future and ATF tests to verify the correctness of the design.
Analysis of the industry, in recent years, with the rapid development of commercial UAV technology, high-end unmanned reveal market potential is emerging, demand for commercial UAV engine more eager. The engine has attracted from the maritime police, agriculture, processing, unmanned aerial vehicle companies, government departments and other areas of concern.
