Hub-mounted actuators for blade pitch collective control [PDF]
, 1985 Blade collective pitch control is provided for a rotor system by rotary actuators located between adjacent blades. Each actuator is connected to the leading edge of one adjacent blade and the trailing edge of the other adjacent ...

FORTRAN program for calculating leading and trailing-edge geometry of turbomachine blades [PDF]
A FORTRAN IV program which calculates leading- and trailing-edge circle radii, tangency angles on the leading- and trailing-edge circles, and stagger angles of turbomachinery blade sections using only spline points defining the blade surfaces is ...

Entropy, 2018 A trailing-edge flap control strategy for mitigating rotor power fluctuations of a 5 MW offshore floating wind turbine is developed under turbulent wind inflow. The wind shear must be considered because of the large rotor diameter. The trailing-edge flap

Estimation of deviation angle for axial-flow compressor blade sections using inviscid-flow solutions [PDF]
Development of a method of estimating deviation angles by analytical procedures was begun. Solutions for inviscid, irrotational flow in the blade-to-blade plane were obtained with a finite-difference calculation method.

Film cooling of turbine blade trailing edges
, 2016 In modern gas turbine engines, film cooling is extensively used to cool the components exposed to the hot mainstream gas path. In implementing film cooling on modern gas turbine engines, the trailing edge film poses a particularly challenging design problem.

Wind turbine noise modeling: prediction of amplitude modulation and influence of atmospheric conditions [PDF]
, 2014 International audienceAeroacoustic noise from a wind turbine is mainly caused by the interaction between the wind turbine blade and the air flow. For a modern wind turbine, trailing edge noise is often the dominant noise source. In this paper, a detailed
