There are 58 undergoing projects in 2023, including 14 new projects.
In the research field of wind energy, the research on applied basic scientificissues, such as wind turbine blades, large floating wind turbine, and wind energy heat utilization, has been carried out.
In the aspect of blade design and test method, 2 MW blade prototype design and demonstration operation were carried out, with an aerodynamic efficiency coefficient greater than or equal to 0.49. Compared with commercial blades of the same capacity and length, the designed annual power generation increased by more than or equal to 2.0%; weight decreased by more than or equal to 5.0%, and the root design ultimate load decreased by more than or equal to 3.5%. A wind turbine blade load assessment method based on high-precision CFD simulation were developed. A high-precision simulation method based on γ-Re θ transition model and wall roughness height correction was established, and accurate prediction of wind turbine airfoil and blade performance under different operating conditions and surface roughness was achieved.
In the aspect of floating wind turbine, a numerical simulation platform based on the actuation line method was developed, achieving highprecision simulation of floating wind turbines. Research on floating wind turbine experimental models were conducted to guide the integrated designper formance prediction and load assessment of floating wind turbineequipment. The unsteady aerodynamic performance and flow field structure of floating wind power under surging and pitching motion were studied, revealing the mechanisms of dynamic stall and dynamic wake under complex motions.
In the aspect of wind energy thermal utilization, an aerodynamic inverse problem design program for wind turbine blades- aero_opt was developed to reveal the heating capacity with different tip speed ratios and the variation law of COP with wind speed. A 2 MW wind-to-heat unit project demonstration was established, and the overall operation experiment was completed, achieving the expected technical indicators.
In the aspect of advanced propulsion systems, research and development have been carried out with the goal of developing new principles for high thrust-to-weight ratio engine and wide-speed-range engine, and key technology research and verification work has been conducted.
With regards to the development of a new principle high thrust-to-weight ratio engine, the design work including overall structural layout of the engine, air system and platform installation system have completed.
For the development of a new-principle wide-speed-range engine, engine assembly and system integration of the first engine have been finished; the joint debugging of the electrical system, the oil system, the supply system, the data acquisition system and the control system was also completed, and the first engine succeeded to ignite and reached 73% of the design speed. Regarding the construction of the engine test platform, the free-jet highaltitude platform has passed system test.
