2. Surgery a piece of tissue partially connected to the body, either following an amputation or to be used as a graft

flap

[flap]
(aerospace engineering)
Any control surface, such as a speed brake, dive brake, or dive-recovery brake, used primarily to increase the lift or drag on an airplane, or to aid in recovery from a dive.
Any rudder attached to a rocket and acting either in the air or within the jet stream.

flap

flap
i. Auxiliary controls built into the wings and used to increase the camber. Flaps may be on the leading or the trailing edges. Trailing edge flaps reduce the stalling angle, whereas leading edge flaps increase the stalling angle when referred to the chord line of the original nonflapped airfoil. Flaps permit aircraft to fly at a lower speed, permitting better control on takeoff and a lower approach speed for landing. Flaps also increase drag, permitting aircraft to descend at a steeper angle. There are various kinds of flaps, such as splits, fowlers, zaps, and slotted.
ii. Short for cowl flaps. See cowl flap.
iii. The up-and-down movement of the tip of a helicopter rotor blade. See flapping.

flap

(storage, jargon)
To unload a DECtape (so it goes flap, flap, flap). Old-time hackers at MIT tell of the days when the disk was device 0 and microtapes were 1, 2, etc. and attempting to flap device 0 would instead start a motor banging inside a cabinet near the disk.

The term is used, by extension, for unloading any magnetic tape. See also macrotape. Modern cartridge tapes no longer actually flap, but the usage has remained.

The term could well be re-applied to DEC's TK50 cartridge tape drive, a spectacularly misengineered contraption which makes a loud flapping sound, almost like an old reel-type lawnmower, in one of its many tape-eating failure modes.

The burden of HN cancer is 21% of the cancers among men and 11% among women across Pakistan.5 Due to socioeconomic circumstances the presentation of Head and neck cancer is usually delayed and almost all (80%) the patients lose precious time (up to 3 years) between first presentation to clinician and final confirmation.6 This delayed presentation causes advancement in local disease which in turn causes larger defect size which usually require reconstruction via a free flap. There are multiple options to choose from when decidingabout the flap that can be used for reconstruction.
Cross finger flaps may be used to resurface defects on any number of segments of either the palmar or dorsal surfaces of a digit but may inflict significant morbidity of the donor site, require two procedures and delay rehabilitation [4].
They also fitted a young ostrich with artificial wings and found that running indeed caused the wings to flap, with longer and larger wings providing a greater lift force.

In the patients who were treated using a Limberg flap, the skin was deepened on the gluteus muscle where the flap was to be raised in the form of a continuation of the rhombus in lengths equal to the sides of the rhombus to encompass the subcutaneous tissue and gluteal muscle fascia for preparing a Limberg flap (Figure 1).
