Abstract Blade design is split into aerodynamic and structural design. The challenge is to design rotor blades for different applications (stall/active stall/pitch regulated wind turbines and/or constant/variable speed) which are optimised in weight and aerodynamic performance.

Shock-free turbomachinery blade design
AIAA Journal, 1985A computational method for designing shock-free, quasi-three-dimensional, transonic, turbomachinery blades is described. Shock-free designs are found by implementing Sobieczky's fictitious gas principle in the analysis of a baseline shape, resulting in an elliptic solution that is incorrect in the supersonic domain.

Computational Design of Turbomachine Blades
Journal of Aircraft, 1980Based upon Wu's general three-dimensional turbomachine flow theory, a set of computer programs was established to measure flow along the relative stream surfaces S1 and S2, employing nonorthogonal curvilinear coordinates and nonorthogonal velocity components.

Flow deflection in turbomachines is established by stator and rotor blades with prescribed geometry that includes inlet and exit camber angles, stagger angle, camber line, and thickness distribution. The blade geometry is adjusted to the stage velocity diagram which is designed for specific turbine or compressor flow applications.

Multidisciplinary turbomachinery blade design optimization
38th Aerospace Sciences Meeting and Exhibit, 2000The development of an optimization environment for multidisciplinary turbomachinery blade design is presented. The optimization environment simplifies the use of various optimization and evaluation methods. An advanced blade parameterization scheme is developed, in order to perform particular blade modifications with a limited number of optimization ...

Design of heterogeneous turbine blade
Computer-Aided Design, 2003Abstract Constantly rising operating pressure and temperature in turbine drivers push the material capabilities of turbine blades to the limit. The recent development of heterogeneous objects by layered manufacturing offers new potentials for the turbine blades.

Aeroacoustic design of a 6-bladed propeller
Aerospace Science and Technology, 1997Abstract By reducing the diameter of a transonic propeller at constant rotational speed a significant noise reduction can be achieved. The number of blades is increased to retain the thrust. For a given design quality a loss in efficiency due to the increased propeller loading can be expected.

Arbitrary Blade Section Design Based on Viscous Considerations. Blade Optimization
Journal of Fluids Engineering, 1996A blade design and optimization procedure is presented in this work, which is based on viscous flow considerations. This procedure concerns the design of optimum rotating arbitrary compressible high subsonic compressor and turbine blade shapes. It takes into account the effects of wall curvature and Coriolis force on turbulence, while it allows the ...

Blade Design with Passive Flow Control Technologies
2020This chapter focuses on the application of passive flow control technologies to wind turbine blades. The motivation of using these technologies is always an enhancement of the wind turbine performance (increase of power production, load reduction, noise reduction, etc.) in comparison to the standard blade.
