Diving-Flight Aerodynamics of a Peregrine Falcon - PMC
Parameters like maximum diving velocity, flight path angle and shape of both body and wing for this particular situation of the flight path were prerequisites to investigate a life-sized model of a peregrine in a wind tunnel at the correct flow conditions and angle of attack.
Aerodynamics of the Cupped Wings during Peregrine Falcon’s Diving Flight
The region of interest shows three flight phases: (1) acceleration/diving phase, (2) transient phase with roughly constant speed and (3) deceleration phase. Maximum velocity during the dive was 22.5 m/s at flight phase (2).
Aerodynamics of the Cupped Wings during Peregrine Falcon’s Diving Flight
This study discusses the aerodynamics of the falcon falco peregrinus in dive flight conditions. In nature on its diving flight the peregrine falcon can reach velocities as high as 300 km/h...

2014年2月5日 · Using these data we built a life-size model of F. peregrinus and used it to measure the drag and lift forces in a wind-tunnel. We compared these forces acting on the model with the data obtained...
Diving-Flight Aerodynamics of a Peregrine Falcon (Falco peregrinus)
Although the nose-diving flight of peregrines has been investigated numerous times, exact measurements of acceleration forces, drag forces, flight path angles and the corresponding aerodynamics of the flow around the body have not been determined.

Illustration of major phases in the springboard dive (Walker, …
Forward running approach dives consist of at least three steps forward, a hurdle which is a higher final step, and a takeoff into the air (Fig. 1). The takeoff propels the diver up and away from...

Figure 13. Polar diagram of the falcon model for a velocity of 22.5 m s21. The angles of attack a varied from 215u to +37u. The increase of the pole line (black dashed line) of the open wing shape is m = 1.93 for the best gliding angle of ag = 21u.
Vortices enable the complex aerobatics of peregrine falcons
2018年4月5日 · During stoop, peregine falcon (Falco peregrinus), can dive at 39 ms −1 1 to 51 ms −1 2, making it the world’s fastest animal. Diving from high altitude is necessary to build-up such speeds.
