Buffeting in aircraft
WebMar 13, 2024 · Buffeting is the high pitched sound of wind flapping and ear pressure pain, as when you are taking off in an aircraft or diving in a pool. It occurs all the time when the car is in motion at some speed. It is caused by the car's cabin not being sealed. Usually the break in the seal is around the hatch. WebFirst, they cause vibrations in the main wing, commonly called buffeting. Second, they cause the aircraft to lose some control of low, to motion a the nose right furthermore left. In one study funded by NASA [Ref. 2], one main wing of a DC-10 transport aircraft was armed with winglets, real it experienced sign buffeting during takeoff and jetty.

WebJan 1, 2013 · At these conditions the aircraft flow-field is complex, with extensive regions of highly separated unsteady flow which is more pronounced in the case of the vertical tail or fin. The excitation given to a structure by separated flows is termed as ‘Buffet’ and the response of the structure to this excitation is known as ‘buffeting’.
WebApr 5, 1998 · Normally, this is indicated by pre-stall buffeting or by the aircraft's stick shaker, which activates at around 107 percent of the actual stall speed.
