Abstract

This paper gives a general review of the development of GRP/composite blades in China, together with their application and advantages.

This paper mainly discusses structural design of 32-m diameter GRP/composite blade for 200-kW wind turbine. Description of the main formulae of aerodynamic loads and centrifugal forces is given. The strength and stiffness of the GRP/composite blade can be calculated and tailored according to the load characteristics. The main amount of fibreglass should be laid in the axial direction of the blade.

The rotating blade is subjected to periodic loads. Because fatigue is serious in large blades, we calculate the structural response by using Friedmann’s aeroelastic modelling.

Blades are a key part of a rotor and their performances have a great influence on the performances of the rotor machine. GRP/composite will be very satisfactory for the aerodynamic and structural requirements of the blade.
