Leading-to-trailing edge theoretical design of a generic scramjet

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...

Two-dimensional Shock Sensitivity Analysis for Transonic Airfoils with Leading-Edge and Trailing-Edge Device Deflections

Divergent selection in trailing- versus leading-edge populations of Biscutella laevigata.

BACKGROUND AND AIMS Knowledge on how climate-induced range shifts might affect natural selection is crucial to understand the evolution of species ranges. METHODS Using historical demographic perspectives gathered from regional-scale phylogeography on the alpine herb Biscutella laevigata, indirect inferences on gene flow and signature of selection based on AFLP genotyping were compared betwee...

Bound attractant at the leading vs. the trailing edge determines chemotactic prowess.

We have analyzed chemotaxis of neutrophil-differentiated HL60 cells in microfluidic devices that create exponential gradients of the chemoattractant, f-Met-Leu-Phe (fMLP). Such gradients expose each cell to a difference in fMLP concentration (DeltaC) across its diameter that is directly proportional to the ambient concentration (C) at that cell's position in the gradient, so the ratio DeltaC/C ...

Continuous Robust Control for Two-Dimensional Airfoils with Leading- and Trailing-Edge Flaps

In this paper, a class of multi-input/multi-output aeroelastic systems with unstructured nonlinear uncertainty is considered. By using leadingand trailing-edge control surface actuations, a continuous robust controller is proposed to suppress the aeroelastic vibrations of a nonlinearwing-sectionmodelwith plunging andpitching degrees of freedom. Under amild restriction that the system uncertaint...
