124Tailless aircraft — A tailless aircraft (often tail less) traditionally has all its horizontal control surfaces on its main wing surface. It has no horizontal stabilizer either tailplane or canard foreplane (nor does it have a second wing in tandem arrangement). A… …
125Oswald efficiency number — The Oswald efficiency, similar to the span efficiency, is a correction factor that represents the change in drag with lift of a three dimensional wing or airplane, as compared with an ideal wing having the same aspect ratio and an elliptical lift …
126Stall (flight) — For other uses, see stall. In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is… …
