Engine-out control system for STOL aircraft - activates flight control surfaces to utilise upper surface blown flaps during take-off or landing manoeuvres with one engine inoperative |
摘要 |
<p>The system for a STOL aircraft monitors internal engine pressure of each engine to detect such engine failure and deploys the upper surface blown flaps, conventional flaps and spoilers used as direct lift control devices to provide a relatively uniform lift distribution across the aircraft wing and hence lower induced drag. When the aircraft executes a STOL takeoff procedure with an engine that does not provide the proper thrust level the upper surface blown flap located aft of thath engine is automatically extended to a position that matches the position of those conventional flaps located outboard of the inoperative engine. Closable spanwise slots in the extended upper surface blown flap are opened to cause the upper surface blown flap to effectively function as a conventional slotted flap.</p> |
