Aerodynamic Optimization of Morphing Airfoil by PCA and Optimization-Guided Data Augmentation

Aerospace
An aircraft that has been carefully optimized for a single flight condition will tend to perform poorly at other flight conditions. For aircraft such as long-haul airliners, this is not necessarily a problem, since the cruise condition so heavily ...

Numerical and experimental investigation of airfoil derived from peregrine FALCON

Measurement: Sensors
In this work, the Peregrine falcon's airfoil is derived and is analysed numerically and experimentally in a non-flapping, non-morphing case. The airfoil is analysed numerically using a Steady State RANS k-ω SST model at different Reynolds numbers with ...

Design and flow simulation of a morphing airfoil

To increase the efficiency of lifting surfaces, such as wings, tails, propeller or wind turbine blades, the concept of morphing (changeable) geometry is gaining popularity and being more and more investigated [1]. With the advances in materials, flexible structures, new production techniques and improved simulations, it is possible to design optimal ...

Lifting-Line Predictions for the Ideal Twist Effectiveness of Spanwise Continuous and Discrete Control Surfaces

Applied Sciences
Modern materials and manufacturing technologies have allowed the construction of morphing wings that are able to continuously vary certain airfoil parameters such as twist, camber, or control surface deflection as a function of span. This work presents a

A Numerical Study on Smart Material Selection for Flapped and Twisted Morphing Wing Configurations

Journal of Aerospace Technology and Management, 2014
The developments of innovative adaptive structures on Unmanned Aerial Vehicles (UAVs), such as morphing wings, can potentially reduce system complexities by eliminating control surfaces and their auxiliary equipment. This technology has the potential of
