Ornithological animals have always benefited from folding their wings during upstroke. So, a Swedish-Swiss research team has constructed a robotic wing that can flap like a bird.
Briefs: Transportation
This simple, elegant invention can control flow separation resulting from the high flap deflections required by simple-hinged flap systems making such flaps a viable option for aircraft designers.
Briefs: Mechanical & Fluid Systems
This trailing edge flap device reduces noise without compromising cruise efficiency or landing lift and stall characteristics.
Briefs: Aerospace
This technique lowers airstream noise generated at the side edges of deployed flaps, elevons, or slats.
Briefs: Motion Control
In the early years of manned flight, wing warping was used for lateral control of an aircraft. This technique consisted of a system of pulleys and cables used to twist the trailing edges of the wings in opposite...
