Leading-edge Vortices Control on a Delta Wing by Micromachined Sensors and Actuators
نویسندگان
چکیده
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 microactuators to manipulate the flow inside the boundary layer around the separation region, resulting in a large change in the three-axis moments. Surface pressure measurements and flow visualization on the upper side of the delta wing have been conducted to explore the physical mechanisms of torque generation and show how micro-actuators alter the vortex structure.

متن کاملExperimental Investigation of Asymmetry of Vortex Flow Over Single Delta Wings
It is generally believed that, on slender delta wings, there is a critical state at which strong asymmetric vortices are found along the leading edge on the lee-side of the delta wing. These asymmetric vortices can lead to high lateral forces even when slender delta wing is at the zero angle of yaw. Some experimental studies reported recently, cast considerable doubt as to the validity of the a...
