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.
Anti-stall (aeroplane controls), a flight envelope protection system designed to prevent an aircraft for stalling, for example by pushing the nose down; Anti-stall strakes, leading-edge slots or extensions, and stall strips; in fluid and aerodynamics, extensions that generates a vortex on a wing surface to postpone aerodynamic stall
Aircraft wing leading-edge extensions – annotated. A leading-edge extension (LEX) is a small extension to an aircraft wing surface, forward of the leading edge. The primary reason for adding an extension is to improve the airflow at high angles of attack and low airspeeds, to improve handling and delay the stall. A dog tooth can also improve ...
A Boeing Co software fix for the grounded 737 MAX will prevent repeated operation of an anti-stall system at the centre of safety concerns and deactivate it altogether if two sensors disagree too ...
By increasing the momentum of the boundary layer, airflow separation and the resulting stall may be delayed. An anti-stall strake is a leading edge extension that generates a vortex on the wing upper surface to postpone the stall. A stick pusher is a mechanical device that prevents the pilot from stalling an aircraft. It pushes the elevator ...
The Joint Authorities Technical Review (JATR) was commissioned by the FAA in April to look into the agency's oversight and approval of the so-called MCAS anti-stall system.
A stick pusher is a device installed in some fixed-wing aircraft to prevent the aircraft from entering an aerodynamic stall. Some large fixed-wing aircraft display poor post-stall handling characteristics or are vulnerable to deep stall.
Strake: a small surface, typically longer than it is wide and mounted on the fuselage. Strakes may be located at various positions in order to improve aerodynamic behaviour. Leading edge root extensions (LERX) are also sometimes referred to as wing strakes. Chine: sharp-edged profile running along the fuselage. When used aerodynamically it is ...
