72Aircraft flight mechanics — In aeronautics, aircraft flight mechanics is the study of the forces that act on an aircraft in flight, and the way the aircraft responds to those forces. [Clancy, L.J. Aerodynamics . Section 14.1] Aircraft flight mechanics are relevant to… …
73Foil (fluid mechanics) — A foil is a surface designed to maximize lift (force generated perpendicular to the fluid flow) while minimizing drag (force generated in the direction of the fluid flow) in a given range of conditions. Foils may be designed to operate in any… …
74Wing configuration — For aircraft configurations in general, including fuselage, tail and powerplant configuration, see Aircraft. For rotary winged aircraft types, see Rotorcraft. For direct lift and compound or hybrid types, see Powered lift. Fixed wing aircraft,… …
75Ground effect in aircraft — Aircraft may be affected by a number of ground effects, aerodynamic effects due to a flying body s proximity to the ground.One of the most important of these effects is the Wing In Ground effect, which refers to the reduction in drag experienced… …

77Downforce — Three different styles of front wings from three different Formula One eras, all designed to produce downforce at the front end of the respective race cars. Top to bottom: Ferrari 312 (1979), Lotus 79 (1978), McLaren MP4 10 (1995) Downforce is a… …
78Slip (aerodynamic) — A slip is an aerodynamic state where an aircraft is moving sideways as well as forward relative to the oncoming airflow. In other words, for a conventional aircraft, the nose will not be pointing directly into the relative wind . Flying in a slip …
79Spin (flight) — In aviation, a spin is an aggravated stall resulting in rotation about the center of gravity wherein the aircraft follows a downward corkscrew path. Spins can be entered unintentionally or intentionally, from any flight attitude and from… …
80Luminiferous aether — The luminiferous aether: it was hypothesised that the Earth moves through a medium of aether that carries light In the late 19th century, luminiferous aether or ether, meaning light bearing aether, was the term used to describe a medium for the… …
