Strake (aeronautics) : ウィキペディア英語版 | Strake (aeronautics)
In aviation, a strake is an aerodynamic surface generally mounted on the fuselage of an aircraft to improve the flight characteristics either by controlling the airflow (acting as large vortex generators) or by simple stabilising effect. In general a strake is longer than it is wide, in contrast to a winglet or a moustache. Leading edge root extensions (LERX) are also sometimes referred to as wing strakes. ==Nose strakes== On both supersonic and subsonic types, smaller strakes are sometimes applied to the forward fuselage to control the fuselage flow at high angles of attack ; for example the Concorde SST has small nose strakes "to get a better directional stability".〔André Peyrat-Armandy, ''Les avions de transport modernes et futurs'', Teknea, 1997, p. 229〕
