Major Progress and Achievements in 2013

R&D related to large wind turbine blades: In the center, five research directions have been developed particularly focusing on key design technologies associated with thick airfoil and flat-back wind turbine blades as well as modular wind turbine blades. These directions are: wind turbine blade airfoils suited for China’s wind resource characteristics; wind resource assessment and wind farm optimization based on China’s meteorological and geological features; inspection technologies and testing standards of wind turbine blades; 3D design methods and design methodology of large wind turbine blades; integrated utilization of wind and marine energy. These studies would provide scientific solutions for difficulties encountered during the development of next generation technologies for wind energy utilization.

Key technology for new type gas turbine engines: The key technology of a new type gas turbine engine was investigated to advance research on the principle prototype. During 2013, all revised designs for the compressor blades, the aerodynamic designs of the two type counter-rotating turbine, the structural design and strength verification check of the compressor and turbine disks, and the overall performance analysis of the two-type engine etc. have been finished. Partial load characteristics experiments of the new concept compressor have been also fulfilled. Experimental verification on the aerodynamic performance on design and off-design conditions was conducted at the short-duration compressor test facility. Based on the requirements of the air ram turbo engine, the design criteria of the stator aspect ratio and design method of the diffuser used between stages have been obtained in partial admission turbines. Based on a multi-variable control schedule, the optimization of thrust and specific impulse has also been achieved under the condition of all flight envelopes. A new type thermodynamic cycle, which adopted the project of supplemental oxygen in the main combustor for altitude condition, has been proposed to meet the increase in fuel caused by the precooling compressor. Meanwhile, analysis and optimization on the new cycle was also performed to get better engine performance.

In 2013, the center had 60 scientific publications, which included 8 papers indexed by SCI and 23 by EI. IET gave 10 oral presentations and reports introducing our work at international conferences. 18 patent proposals have been submitted and 8 patents have been authorized.
