Design and Performance Prediction of Swashplateless Helicopter Rotor with Trailing Edge Flaps and Tabs
Title of dissertation: DESIGN AND PERFORMANCE PREDICTION OF SWASHPLATELESS HELICOPTER ROTOR WITH TRAILING EDGE FLAPS AND TABS Jaye Falls, Doctor of Philosophy, 2010 Dissertation directed by: Professor Inderjit Chopra Department of Aerospace Engineering This work studies the design of trailing edge controls for swashplateless helicopter primary control, and examines the impact of those controls ...
متن کاملA Comparison of Smart Rotor Control Approaches Using Trailing Edge Flaps and Individual Pitch Control
Modern wind turbines have been steadily increasing in size, and have now become very large, with recent models boasting rotor diameters greater than 120 m. Reducing the loads experienced by the wind turbine rotor blades is one means of lowering the cost of energy of wind turbines. Wind turbines are subjected to significant and rapid fluctuating loads, which arise from a variety of sources inclu...

متن کاملAn investigation of unsteady 3D effects on trailing edge flaps
The present study investigates the impact of unsteady and viscous three-dimensional aerodynamic effects on a wind turbine blade with trailing edge flap by means of CFD. Harmonic oscillations are simulated on the DTU 10 MW rotor with a flap of 10% chord extent ranging from 70% to 80% blade radius. The deflection frequency is varied in the range between 1p and 6p. To quantify 3D effects, rotor si...
متن کاملMulti-body Aeroelastic Analysis of Smart Rotor Blades, Actuated by Means of Embedded Piezo-electric Devices
The paper describes an unusual C beam discretization based on the finite volumes concept. The formulation is developed in the linear (linearised) case first; eventually a non-linear multi-body approach to the same problem, based on previous works [9], is presented. The formulation is generalised to the piezo-electric beam in both cases, with reference to work [10]. Some applications are outline...
