downwash — i. Fluid flow moving at a deflected angle after deflection by helicopter rotors and measured parallel to the disc. ii. Fluid flow deflected at an angle more perpendicular to the motion of the airfoil, measured in the plane parallel to the plane… … Aviation dictionary
transverse flow effect — The unequal drag in the fore and aft parts of the rotor disc, which results in vibrations in most helicopters at speeds between 10 and 20 knots. In forward flight, air passing through the rear portion of the rotor disc has a greater downwash… … Aviation dictionary

Longitudinal static stability — is important in determining whether an aircraft will be able to fly as intended. Static stability As any vehicle moves it will be subjected to minor changes in the forces that act on it, and in its speed. * If such a change causes further changes … Wikipedia
Vortex — A vortex (pl. vortices ) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the… … Wikipedia
Lift-induced drag — In aerodynamics, lift induced drag, induced drag, vortex drag, or sometimes drag due to lift, is a drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting… … Wikipedia
