Investigation of Flapping Wings as an Alternative to Axial Flow Fans
Flapping wings appear to be an innovative approach as an alternative to axial flow fans. In this study, the flapping motion has been defined as a linear combination of pitching and plunging. Both pitch and plunge motions have been given as sinusoidal in time with a phase shift between them.

Twist Optimization of a Helicopter Rotor Blade Using Support Vector Regression
Solving the Reynolds Averaged Navier-Stokes (RANS) equations is essential for an accurate estimation of the aerodynamic loads on the helicopter rotor blades. This is highly time consuming process, especially, in the case of blade shape optimization in which several RANS solutions are obtained using Computational Fluid Dynamics (CFD) solvers. A recent approach to diminish the duration of computation is to employ metamodels like machine learning techniques.
