RISImpact of Gurney Flaplike Strips on the Aerodynamic and Vortex Flow Characteristic of a Reverse Delta Wing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The impact of Gurney flaplike strips, of different geometric configurations and heights, on the aerodynamic characteristics and the tip vortices generated by a reverse delta wing (RDW) was investigated via forcebalance ...
Wingtip Vortex Control Via Tip Mounted Half Delta Wings of Different Geometric Configurations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The control of the tip vortex, generated by a rectangular NACA 0012 wing, via tipmounted halfdelta wings (HDWs), of different slendernesses خ›, root chords cr, and deflections خ´, was investigated experimentally at ...
Effect of Ground Boundary Condition on Near-Field Wingtip Vortex Flow and Lift-Induced Drag
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ground proximity is known to induce an outboard movement and suppression of the wingtip vortices, leading to a reduced lift-induced drag. Depending on the ground boundary condition, a large scatter exists in the published ...
Surface Pressures Developed on an Airfoil Undergoing Heaving and Pitching Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The surface pressure distributions and flow patterns developed on and around a NACA 0012 airfoil undergoing heaving and pitching were investigated at Re = 3.6 أ— 104. Despite extensive investigations conducted by ...
Aerodynamics and Vortex Flowfield of a Slender Delta Wing With Apex Flap and Tip Flap
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of apex flap and tip flap, deflected both independently and jointly, on the vortex flow and lift generation of a 65 deg-sweep delta wing was investigated experimentally. The drooped apex flap produced a higher ...
