Objective
Objectives
The overall objective is to develop a low noise blade specifically for operation on variable speed, pitch regulated wind turbines. The specific objectives of the project are :
- to undertake a thorough investigation of blade design for variable speed wind turbines with specific emphasis being placed on techniques to reduce aerodynamic noise emission from the rotor
- to obtain comprehensive noise measurements from a variable speed wind turbine
- to optimise the blade geometry and specify the required aerofoil characteristics necessary for a low noise blade.
- to develop aerofoil and blade designs to achieve the required aerodynamic noise and performance characteristics.
Technical Approach
Noise measurements will be made by Renewable Energy Systems (RES) on Markham's 45m variable speed wind turbine (VS45) using DAT recordings and synchronous measurements of wind speed, wind direction, power, tip speed, pitch angle, blade bending moments and yaw. RES will then analyse the noise measurements to "fine-tune" the noise prediction code and establish the sensitivity of noise emission to blade geometry, aerofoil details and operating conditions to enable the definition of optimum blade characteristics for a low noise variable speed turbine. The Aeronautical Research Institute of Sweden (FFA) will then select or design the blade and aerofoil geometry to fulfil the design requirements subject to structural constraints determined by Aerpac B/V in parallel with price/performance considerations while emphasising the noise aspects. The final design will be reviewed to assess the cost and performance of the new blades in relation to the cost of energy for a variable speed wind turbine, and also assess the effect on the cost of energy for a number of typical wind farm sites.
Expected Achievements and Exploitation
The outputs of this project are :
- the measured noise data from the Markham VS45
- the results of the parametric and sensitivity studies carried out to identify the features for the blade and aerofoil
- technical details of the proposed aerofoils
- a design report ready for certification
- a drawing set ready for use in blade manufacturing
