What you will learn in this article What brownouts and whiteouts are, and why they are phenomena unique to helicopters The ...

UK researchers believe they have discovered a “powerful new approach” to demonstrate safety risks posed by hovering helicopters and other vertical take-off vehicles by using video simulations to ...

Additional lift can be created only by increasing the downwash of air behind the wing. Aerodynamicists are aware of this and try to get as much air above the wing as possible because all of it will ...

Wingtip vortices, formed by pressure differentials at the wingtips, create lift-induced drag (downwash) that affects both the generating aircraft and those following it. Ground effect reduces ...

Lift generation is a complex, dynamic process best understood by combining Bernoulli's principle (low pressure above the wing) and Newton's Third Law (downward deflection of air), as neither theory ...

If you've ever watched a helicopter lift off the ground, you've probably noticed that they always pitch forward, tossing their nose toward the ground. This isn't by accident — in fact, it's crucial to ...
