The Symphony SA-160 was designed with two unusual vortex generators on its wing to ensure aileron effectiveness through the stall. A vortex generator (VG) is an aerodynamic device, consisting of a small vane usually attached to a lifting surface (or airfoil, such as an aircraft wing) [1] or a rotor blade of a wind turbine. [2]
When the speed is reduced and the aircraft approaches stall, the local flow at the leading edge is diverted outwards; this spanwise component of velocity around the vortilon creates a vortex streamed around the top surface, which energises the boundary layer. [6] A more turbulent boundary layer, in turn, delays the local flow separation.
A Quickie Q2, with vortex generators on the canard. The Quickie Aircraft Corporation was founded in Mojave, California, in 1978 to market the Quickie homebuilt aircraft (models Quickie, Quickie Q2, and Quickie Q200 aircraft). The original single-seater Quickie was designed by Burt Rutan and company founders Gene Sheehan and Tom Jewett.
On aircraft with swept wings, wing tip stall also produces an undesirable nose-up pitching moment which hampers recovery from the stall. Washout may be accomplished by other means e.g. modified aerofoil section, vortex generators, leading edge wing fences, notches, or stall strips. This is referred to as aerodynamic washout.
Fisher Flying Products is a Canadian aircraft manufacturer that produces kits for a wide line of light aircraft. The company's kits all feature wooden construction with aircraft fabric covering. Many of the designs are reproductions of classic aircraft, such as the company's 80% Fisher R-80 Tiger Moth that is based upon the de Havilland Tiger Moth.
A plasma actuator induces a local flow speed perturbation, which will be developed downstream to a vortex sheet. As a result, plasma actuators can behave as vortex generators. The difference between this and traditional vortex generation is that there are no mechanical moving parts or any drilling holes on aerodynamic surfaces, demonstrating an ...
An experimental, homemade aircraft crashed about 70 miles (111 kilometers) southwest of Phoenix, killing one person and seriously injuring another, authorities said. The aircraft went down at ...
AkroTech Aviation, Inc. was an American aircraft manufacturer based in Scappoose, Oregon. The company specialized in the design and manufacture of kits for aerobatic aircraft. The company went out of business after 1998. [1] [2] The company's two designs, the single-seat Giles G-200 and the two-seat G-202 were built from composites.
