The laboratory currently has 121 employees, including 15 professors, 21 associate professors/senior engineers; 65 graduates and 4 postdoctoral researchers.

Projects and Major Achievements

Regarding the lightweight turbofan engine, a certain engine has completed the prototype certification and has been installed on a high-speed unmanned aerial vehicle for multiple flight tests, achieving small-scale engine delivery. The engine has also undergone component and system improvements, and has completed high-altitude acceleration and deceleration, intake distortion, and high-altitude fuel return tests, improving the engine's reliability during highaltitude operation. The engine has been installed on a series of unmanned aerial vehicles and has completed multiple scientific research flight missions.
 
 In the field of lightweight turbine engines, key technologies for single-shaft turbine engines have been developed, resulting in the creation of a highefficiency cost ratio single-shaft turbine engine. The engine's reliability and high-altitude performance have been tested and verified. Additionally, research has been conducted on the development of lightweight turbine engines with high unit thrust for supersonic unmanned aerial vehicles, and the engine's endurance and high-altitude performance have been tested. Breakthroughs have been made in key technologies such as annular spaced center swirling oxygen-enriched atomization nozzles and anchored high-altitude combustion chamber ignition conditions, and high-altitude rapid start-up technology tests have been successfully completed.
 
In terms of basic research, the "Gas Turbines and Aero Engines" special basic research project which we led passed the second milestone evaluation; the basic strengthening project has also successfully passed its node evaluation. Additionally, the civil aircraft research project has been successfully accepted.
 
As for the "Chung-Hua" thermal physics test device, the preliminary design and budget review of the key components of the suction-type engine thermal physics test device have been completed, and approval has been obtained from the Chinese Academy of Sciences and the National Development and Reform Commission. The bidding and procurement of the gas supply system and the gas extraction system have been completed, and the detailed design of the test cabin and the civil engineering design of the 101 central control and data center have been carried out, laying the foundation for the subsequent implementation of the project.
 
In 2022, there are 65 ongoing projects, and 17 new projects have been approved, including 4 key projects in the field of basic science for aero engine and gas turbines, 2 general projects funded by the National Natural Science Foundation, 1 youth project funded by the National Natural Science Foundation, 5 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, 1 self-deployed project by the research institute, and 3 commissioned projects from enterprises. Six projects have been completed and passed the acceptance inspection.
