Title :Aerodynamic optimization design and analysis of wind turbine blade based on inverse design method 

Abstract:Nowadays, wind power is paid more and more attention because of its high efficiency and clean。 In our country, wind energy reserves are abundant, so the research of wind turbine is of high value。 Blade is the core component of the wind turbine and its aerodynamic shape directly affects the efficiency of wind turbine power generation。 Therefore, the design and optimization of the aerodynamic shape of the wind turbine is the key to the study of wind turbines。 

This paper mainly studies an inverse method for aerodynamic design of wind turbine blades based on PROPID program, which is pided into five chapters: 

The first chapter mainly introduces the research status of aerodynamic design of wind turbine blades, as well as the research content and methods of this paper; 

In the second chapter, the basic principle of pneumatic design of wind turbine is summarized; 

In the third chapter, the method of using the PROPID program and the method of designing the wind turbine blade using PROPID software are described; 

In the fourth chapter, the design and optimization of the 1。5MW based wind turbine is designed, and its aerodynamic performance is analyzed; 

In the fifth chapter, the design results of this article are summarized, and some suggestions for future design and research are made。
