Icing can significantly change the geometric parameters of wind turbine blades, which in turn, reduce aerodynamic characteristics airfoil. In-depth research is conducted this study to identify reasons for decline power equipment performance through icing process. An accurate experimental test method proposed a natural environment that examines growth and distribution ice formation over airfoil ...

Since the taper ratio of most wings is not equal to 1, beam-disk trailing edge deflection mechanism originally designed for rectangular wing fully applicable non-equal chord wing. Moreover, it only expected that shape can achieve excellent aerodynamic performance under different flight conditions, but one also needs consider whether flexible skin this deformation. This paper used honeycomb comp...

A morphing wing concept allowing for coupled twist-camber shape adaptation is proposed. The design based on an optimized thickness distribution both spanwise and chordwise to be able morph the sections into targeted airfoil shapes. Simultaneously, twist affected by actuation. provides a higher degree of control lift which can used roll control, drag minimization, active load alleviation. Static...

Abstract The aerodynamical optimal design (OD) of the shape of flying configurations (FCs) can be improved by refinements of its start software used for the optimization and of the optimization strategy itself. The author has two times enlarged the classical variational method. The first one consists in the inviscid global OD of the FC’s shape (the optimization of the camber, twist, thickness a...

A diversity of efficient solutions for flapping flight have evolved in nature; however, it is often difficult to isolate the key characteristics of efficient flapping flight from biological constraints. Rather than base micro aerial vehicle (MAV) design on natural flyers alone, we propose a multi-fidelity computational approach for analysis and design. At the lowest fidelity level, we use a wak...
