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 a 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.
