elliptical wing
1Elliptical wing — An elliptical wing is a wing planform shape, first seen on aircraft in the 1930s, which minimizes induced drag. Elliptical taper shortens the chord near the wingtips in such a way that all parts of the wing experience equivalent downwash, and… …

5Aspect ratio (wing) — In aerodynamics, the aspect ratio of a wing is defined as the square of the wing span divided by the wing area.:AR = {b^2 over S}where: b is the wing span, and: S is the wing area.Informally, a high aspect ratio indicates long, narrow wings,… …

7Lift-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… …
8Powered parachute — A powered parachute (motorized parachute, PPC, paraplane) is a parachute with motor and wheels. The aircraft s airspeed is typically about 25–35 mph (40–60 km/h). PPCs operate safely at heights ranging from a few feet off the ground (while ground …
