The leading-edge vortex of swift wing-shaped delta wings
Recent investigations on the aerodynamics of natural fliers have illuminated the significance of the leading-edge vortex (LEV) for lift generation in a variety of flight conditions. A well-documented example of an LEV is that generated by aircraft with highly swept, delta-shaped wings. While the wing aerodynamics of a manoeuvring aircraft, a bird gliding and a bird in flapping flight vary signi...
متن کاملLeading-edge Vortices Control on a Delta Wing by Micromachined Sensors and Actuators
Instead of using conventional flaps to generate torques, we explore the feasibility of applying micromachined sensors and actuators to control leading-edge vortices, and consequently, provide sufficient moments for flight control. By utilizing a “flexible skin” containing 64 micromachined shear stress sensors, instantaneous separation line on the leading edges can be detected. We applied microa...
متن کاملThe effect of aspect ratio on the leading-edge vortex over an insect-like flapping wing.
Insect wing shapes are diverse and a renowned source of inspiration for the new generation of autonomous flapping vehicles, yet the aerodynamic consequences of varying geometry is not well understood. One of the most defining and aerodynamically significant measures of wing shape is the aspect ratio, defined as the ratio of wing length (R) to mean wing chord (c). We investigated the impact of a...

متن کاملDirect measurement of delta wing vortex circulation using ultrasound
The circulation around a closed path encompassing the primary vortex of stationary delta wings is investigated through the use of ultrasound. Ultrasonic pulses were propagated clockwise and counterclockwise along a fixed, closed path which was positioned perpendicular to the delta wing root chord lines. Circulation in the plane of the closed path was then determined from the transit time differ...
