Aerodynamic Analysis of Variable Camber-Morphing Airfoils with Substantial Camber Deflections

Energies
In recent years, morphing wings have become not only a concept, but an aerodynamic solution for the aviation industry to take a step forward toward future technologies. However, continuously morphing airfoils became an interesting answer to provide green

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 ...

Morphing of ‘flying’ shapes for autonomous underwater and aerial vehicles

, 2009
Autonomous vehicles are energy poor and should be designed to minimise the power required to propel them throughout their mission. The University of Southampton’s School of Engineering Sciences is actively involved in the development of improved designs ...

Feasibility and principle analyses of morphing airfoil used to control flight attitude [PDF]

, 2012
Morphing airfoil technology can enable an aircraft to adapt its shape to enhance mission performance and replace the traditional flap, ailerons, elevator and rudders to optimize flight attitude control efficiency.

Airfoil noise reduction using morphing trailing edge

, 2014
A novel airfoil noise reduction technique, based on morphing structures, has been introduced and investigated. In order to achieve high aerodynamic performance and reduce the noise, a new morphing flap concept based on a bending stiffness tailored ...
