An ornithopter (from Greek ornis, ornith- "bird" and pteron "wing") is an aircraft that flies by flapping its wings. Designers sought to imitate the flapping-wing flight of birds, bats, and insects. Though machines may differ in form, they are usually built on the same scale as flying animals. Larger, crewed … See more Some early crewed flight attempts may have been intended to achieve flapping-wing flight, but probably only a glide was actually achieved. They include the purported flights of the 11th-century Catholic See more Practical applications capitalize on the resemblance to birds or insects. Colorado Parks and Wildlife has used these machines to help save the endangered Gunnison sage grouse. An artificial hawk under the control of an operator causes the grouse to … See more As demonstrated by birds, flapping wings offer potential advantages in maneuverability and energy savings compared with … See more • Cyclogyro • Gyroplane • Helicopter • Human-powered aircraft • Insectothopter • Micro air vehicle See more Crewed ornithopters fall into two general categories: Those powered by the muscular effort of the pilot (human-powered ornithopters), and those powered by an engine. Around 1894, Otto Lilienthal, an aviation pioneer, became … See more Hobbyists can build and fly their own ornithopters. These range from light-weight models powered by rubber bands, to larger models with radio control. The rubber-band-powered model can be fairly simple in design and construction. Hobbyists See more Ornithopters have been depicted in fiction several times, including Frank Herbert's Dune series, where they are the primary form of transportation in the desert setting.

A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. WebAug 16, 2024 · Flaps help to either increase or decrease the camber, or surface area, of the airplane wing.
