Peregrine Falcon’s Dive: Pullout Maneuver and Flight Control Through Wing Morphing
نویسندگان
چکیده
During the pullout maneuver, peregrine falcons were observed to adopt a succession of specific flight configurations that are thought offer an aerodynamic advantage over aerial prey. Analysis trajectory falcon in controlled environment shows it experiencing load factors up , and further predictions suggest this could be increased almost during high-speed pullout. This can attributed high maneuverability promoted by lift-generating vortical structures wing. Wind-tunnel experiments on life-sized models different together with high-fidelity computational fluid dynamics simulations (large-eddy simulations) show deploying hand wing creates extra vortex lift, which is similar combat aircraft delta wings. The forces position center calculated from flow around configurations. allowed for analysis longitudinal static stability early phase, confirming flying unstably pitch positive slope pitching moment trim angle attack about 5 deg, possibly maximize responsiveness. wings/primaries seen contribute augmented stability, acting as “elevons” would tailless blended-wing/body aircraft.

Curved flight paths and sideways vision in peregrine falcons (Falco peregrinus).
When diving at prey straight ahead from great distances at high speeds, a peregrine has a conflict between vision and aerodynamics: it must turn its head approximately 40 degrees to one side to see the prey with maximum visual acuity at the deep fovea of one eye, but the head in this position increases aerodynamic drag and slows the falcon down. The falcon could resolve this conflict by holding...
متن کاملEffectiveness of Call-broadcast Surveys to Detect Territorial Peregrine Falcons
—We developed and tested a 10-min call-broadcast survey protocol using conspecific vocalizations to assess Peregrine Falcon (Falco peregrinus) territory occupancy in the Mojave Desert of southern Nevada and northwestern Arizona from 2008–10. Response rate of peregrines, when adults were confirmed present immediately prior to broadcasting, averaged 83% during the breeding season and peaked at 10...
متن کاملMorphing Wing Technologies Research
The development of innovative adaptive structures on UAVs (and UUVs), such as morphing wings, can potentially reduce system complexity by eliminating control surfaces and their auxiliary equipment. This technology has the potential of allowing a UAV to adapt to different mission requirements or executing a particular mission more effectively. The first part of the paper deals with a review of m...
متن کاملBat wing sensors support flight control.
Bats are the only mammals capable of powered flight, and they perform impressive aerial maneuvers like tight turns, hovering, and perching upside down. The bat wing contains five digits, and its specialized membrane is covered with stiff, microscopically small, domed hairs. We provide here unique empirical evidence that the tactile receptors associated with these hairs are involved in sensorimo...
متن کاملControl System Design for a Morphing Wing Trailing Edge
Shape control of adaptive wings has the potential to enhance wing aerodynamic performance during cruise and high-speed off-design conditions. A possible way to attain this objective is to develop specific technologies for trailing edge morphing, aimed at variating the airfoil camber. In the framework of SARISTU project (EU-FP7), an innovative structural system incorporating a gapless deformable...
