Lift Enhancement of Delta Wing with Trailing Edge Jet

Morphing Trailing Edge Flap for High Lift Wing

This paper presents the study conducted to design and analyze a morphing trailing edge flap structure for a large aircraft wing. The rear part of the trailing edge flap was modified to be integrated with a set of internal actuation mechanisms distributed along the span of the flap. Additional changes to the conventional flap structure were implemented, such as an open sliding trailing edge and ...

Aerodynamic Shape Optimization of an Adaptive Morphing Trailing Edge Wing

Adaptive morphing trailing edge wings have the potential to reduce the fuel burn of transport aircraft. In this paper, we quantify the aerodynamic performance benefits of a morphing trailing using aerodynamic design optimization. The aerodynamic model solves the Reynolds-averaged Navier– Stokes equations with a Spalart–Allmaras turbulence model. A gradient-based optimization algorithm is used i...

Control System Design for a Morphing Wing Trailing Edge

Shape control of adaptive wings has the potential to enhance wing aerodynamic performance during cruise and high-speed off-design conditions. A possible way to attain this objective is to develop specific technologies for trailing edge morphing, aimed at variating the airfoil camber. In the framework of SARISTU project (EU-FP7), an innovative structural system incorporating a gapless deformable...
