Are they in the same aerodynamic regime? Or, can a humble roach be a source of inspiration?

"Identification of major forces is critical to understanding insect flight. The first attempts to understand flapping wings assumed a quasi-steady state... The calculated lift was too small by a factor of three, so researchers realized that must be unsteady phenomena providing aerodynamic forces. ... Through computational fluid dynamics, some researchers argue that there is no rotational effect. They claim that the high forces are caused by an interaction with the wake shed by the previous stroke.

One of the most important phenomena that occurs during insect flight is leading edge suction... At high angles of attack, the flow separates over the leading edge but reattaches before reaching the trailing edge. Within this bubble of separated flow is a vortex. Because the angle of attack is so high, there is a lot of momentum transferred downward into the flow. These two features create a large amount of lift force as well as some additional drag. The important feature, however, is the lift. Because the flow has separated, yet it still provides large amounts of lift, this phenomenon is called “delayed stall.” This effect was observed in flapping insect flight, and it was proven to be capable of providing enough lift to account for the deficiency in the quasi-steady state models.
All of the effects on a flapping wing can be reduced to three major sources of aerodynamic phenomena: the leading edge vortex, the steady-state aerodynamic forces on the wing, and the wing’s contact with its wake from previous strokes."
Anyway, I plan to follow with some structures for birds that I find have some promise... I suppose somebody must have tried to take a look before. Do you have any links for bionics and F1? You've got me totally wrong, miqi: I was thinking about the McLaren wing... (go, Alonso!)miqi23 wrote:... the Renault front wing isnt flapping!
