Projects Overview

In 2023, there are more than 60 ongoing projects, and 15 new projects have been approved, including 1 general project funded by the National Natural Science Foundation of China, 3 youth projects funded by the National Natural Science Foundation of China, 1 key project for major projects on aero engine and gas turbines basic science center, 2 basic research projects for major projects on aero engine and gas turbines, 1 talent project funded by the Chinese Academy of Sciences Youth Promotion Association, 2 self-deployed projects by the research institute, and 4 commissioned projects  from enterprises. 8 projects have been completed and passed the acceptance inspection.

Project and Major Achievement

In terms of high-altitude, low-fuel-consumption light turbofan engines, a certain type of light turbofan engine has completed all flight tests when installed on a certain type of unmanned aerial vehicle, and has successfully passed the project acceptance; when installed on a certain type of unmanned aerial vehicle, it has completed full envelope performance flight tests and passed technical status identification; a certain type of light multi-electric turbofan engine has completed overall performance, bleed air, power supply, and intake distortion tests, and has the conditions for first flight after a 60-hour endurance test.

Key breakthroughs have been made in the development of single-shaft turbofan engines with high efficiency and low specific fuel consumption. A series of high-efficiency single-shaft turbofan engines have been developed, with the 300-kilogram-thrust level engine successfully completing its first flight when installed on a certain type of equipment, and the 180-kilogram-thrust level engine completing its first flight when installed on a certain reconnaissance and strike system. These achievements have been highlighted in the CAS director's report for the 2024 annual work conference. Furthermore, significant progress has been made in key technologies such as the swirl oxygenation and atomization nozzles in annular interstage combustion and the ignition conditions for high-altitude combustion chambers, as well as the development of smokeless and high energy preheating for rapid high-altitude starting of light turbojet engines. This technology has been successfully verified, and in conjunction with a certain type of equipment, rapid high-altitude starting has been achieved, resulting in a successful bid.

Regarding the “Chung-Hua” Thermal Physics Test Device, the high-altitude low-Reynolds number compression matching test cabin for key components of the air-breathing engine (Cabin 1), the wide-area combustion chamber and turbine gas-thermal coupling test system (Cabin 2), the wide-area air intake engine air system test cabin (Cabin 3), and detailed design of the gas supply and other systems have been completed, and the construction project has started.

In terms of basic research, one “LJ” special basic research project has passed the project acceptance, while two others are qualified for acceptance. Two basic reinforcement projects have successfully passed the milestone assessment. Two civil aircraft research projects have passed the acceptance, and the National Natural Science Foundation key project of China "Research on the internal flow mechanism and design method of ultra-high-load lowpressure turbine" has successfully passed the acceptance.
