In the research field of wind energy, the research on applied basic scientific issues, such as wind turbine blades, large floating wind turbine, and wind energy heat utilization, have been carried out.
In wind turbine blades, multi-objective optimization and decision-making methodology, the development of aerodynamic parameterization, structural parameterization and blade performance calculation and other core modules were established. A new type of stall risk assessment criteria and fatigue characteristics assessment criteria were constructed, and the multiobjective optimization was developed. The design and external testing of the 151-meter ultra-long flexible blades were completed, and passed the on-site witness.
In terms of floating wind turbine, a new dynamic aerodynamic similarity theory and a wind tunnel experimental model design method based on multi-objective genetic algorithm were proposed, laying an important foundation for the development of high-fidelity wind tunnel model experiments and the exploration of multi-body and multi-field coupling
mechanism. An experimental platform for AI in-the-loop testing of floating wind pool was set up, which can realize the motion data capturing. The training of the AI module and the loading of the rotor thrust were completed.
In the area of wind energy heat utilization, the design of wind energy, solar energy and storage system was completed. The performance test platform of the Photovoltaic-Thermal Integrated System was built. A new control logic for the wind-to-heat unit, which increased the power by 1.16%, the projected annual heat production by 1.07%, and the wind energy utilization hours by 1.68%, was developed.
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 processing of various engine components was completed, and preparations for assembly and ground testing are under way. On this basis, the engine low-cost optimization design was carried out to realize the key project of high thrust-to-weight ratio turbojet engine.
For the development of a new-principle wide-speed-range engine, the engine ground operation debugging and ignition test were carried out, and the engine was successfully ignited to reach 100% of the designed speed and about 60% of the designed thrust.
Regarding the construction of the engine test platform, the modification of the direct-connected high-altitude simulation test function of the aerodynamic test platform was organized, and the debugging of the pressure, temperature and flow parameters of the gas supply at the test condition points was completed.
