Q] is unit normal vector on the flapping hydrofoil surface, [Q.
The perturbation velocities V (x, y, z, t) on the flapping hydrofoil surface are evaluated by differentiating the velocity potential on the flapping hydrofoil surface.
By Bernoulli's theorem the pressure on the flapping hydrofoil surface can be expressed as [12]
The hydrodynamic characteristics are obtained by integrating the pressure on the flapping hydrofoil surface.
We tried to gain insight into the flapping aerodynamics by using computational models and identifying the aerodynamic forces necessary to drive these very small flying machines," said Alexeev.
In addition, the simulations identified one flapping regime that enabled maximum lift and another that revealed maximum efficiency.
The efficiency was maximized at a flapping frequency 30 percent higher than the frequency for maximized lift.
Moreover, he predicts, "there are going to be some breakthroughs here in understanding the aerodynamics of flapping wings and very small rotary blades," advances that could change the character of Earth's own flying fleets.
However, "running gas through a flapping wing is something absolutely new," Michelson says.

If most of these tracks are 'everything that is wrong with the game, why do top NGRC trainers still come to pinch the flapping money
