Covert-inspired flaps for lift enhancement and stall mitigation

Bioinspiration & Biomimetics, 2021
Even though unmanned aerial vehicles (UAVs) are taking on more expansive roles in military and commercial applications, their adaptability and agility are still inferior to that of their biological counterparts like birds, especially at low and moderate Reynolds numbers.

Lift Enhancement for Upper Surface Blowing Airplanes

31st AIAA Applied Aerodynamics Conference, 2013
Various flow control techniques are applied to airplane configurations that utilize Upper Surface Blowing (USB) in order to enhance their takeoff and landing capabilities. These techniques include geometrical changes to the lifting surfaces and the engine nozzle.

Lift enhancement of a butterfly-like flapping wing vehicle by reinforcement learning algorithm

Bioinspiration & Biomimetics, 2023
In order to enhance the take-off lift of a butterfly-like flapping wing vehicle (FWV), we implemented an integrated experimental platform and applied a reinforcement learning algorithm. The vehicle, which has a wingspan of 81 cm and is mounted on a stand

Lift Enhancement of Supersonic Thin Airfoil at Low Speed by Co-Flow Jet Active Flow Control

AIAA AVIATION 2021 FORUM, 2021
This paper numerically studies a lift enhancement approach for a supersonic thin airfoil with t/c of 3.2% using Co-Flow Jet (CFJ) active flow control at Mach number of 0.1.

Lift-enhancing tabs on swept, three-dimensional high-lift systems

14th Applied Aerodynamics Conference, 1996
A three-dimensional high-lift system was computationally simulated to investigate the effectiveness of lift-enhancing tabs on swept wings. The computations were performed by solving the incompressible Navier-Stokes equations on structured, overset grids, and the effects of turbulence were simulated using the one-equation Baldwin-Barth model.

Random Roughness Enhances Lift in Supersonic Flow

Physical Review Letters, 2007
We study the scattering of shock waves by a rough wedge using second-order perturbation analysis and stochastic simulations employed synergistically to cover a large range in correlation length A and amplitude epsilon of the profile roughness (with length d).
