Design-Oriented Aerodynamic Analysis for Supersonic Laminar Flow Wings
The computation of boundary layer properties and laminar-to-turbulent transition location is a very complex problem, generally not undertaken in the context of aircraft design. Yet if an aircraft is to exploit the advantages of laminar flow and proper trade-offs between inviscid drag, structural weight, and skin friction are to be made, this is just what must be done. This paper summarizes a de...
متن کاملUnsteady-State Aerodynamic Performance of MEMS Wings
The unsteady-state aerodynamic performance results of various MEMS-fabricated titanium-alloy wing designs are presented. These wing are tested in a high-quality low-speed wind tunnel with velocity uniformity of 0.5%.. For the first time, we have identified the importance of spanwise stiffness effect in generating the leading edge vortices. These vortices, generated around each wing, cause a low...
متن کاملAerodynamic effects of flexibility in flapping wings.
Recent work on the aerodynamics of flapping flight reveals fundamental differences in the mechanisms of aerodynamic force generation between fixed and flapping wings. When fixed wings translate at high angles of attack, they periodically generate and shed leading and trailing edge vortices as reflected in their fluctuating aerodynamic force traces and associated flow visualization. In contrast,...
متن کاملAerodynamic characteristics of the wings and body of a dragonfly
The aerodynamic characteristics of the wings and body of a dragonfly and of artificial wing models were studied by conducting two types of wind-tunnel tests and a number of free-flight tests of gliders made using dragonfly wings. The results were consistent between these different tests. The effects of camber, thickness, sharpness of the leading edge and surface roughness on the aerodynamic cha...
متن کاملEffects of Flexibility on the Aerodynamic Performance of Flapping Wings
Effects of chordwise, spanwise, and isotropic flexibility on the force generation and propulsive efficiency of flapping wings are elucidated. For a moving body immersed in viscous fluid, different types of forces, as a function of the Reynolds number, reduced frequency (k), and Strouhal number (St), acting on the moving body are identified based on a scaling argument. In particular, at the Reyn...
