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 ...

Effect of Graphene Addition on Shape Memory Behavior of Epoxy Resins [PDF]

, 2011
Shape memory polymers (SMPs) and composites are a special class of smart materials known for their ability to change size and shape upon exposure to an external stimulus (e.g. light, heat, pH, or magnetic field).

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 ...

Modeling and control of a morphing airfoil structure

, 2020
The aeroelastic modeling and robust control design for a morphing airfoil concept is presented. A finite dimensional linear time invariant aeroelastic model was developed for a multi-input, multi-output morphing airfoil structure. The shape of the airfoil (NACA airfoil series 2415) was controlled by actuators distributed along the top airfoil surface ...
