Title:
INFLATABLE AIRFOIL DEVICE
Document Type and Number:
WIPO Patent Application WO2002024525
Kind Code:
A3
Abstract:
An airfoil device (10) for attachment to the wing (14) of an aircraft (12). The airfoil device (10) has a chamber (30) which is inflatable to provide a lift-enhancing airfoil geometry to the wing (14) and other chambers (32) which are inflatable to provide deicing forces to remove ice accumulation on the wing (14). When installed on the wing (14), the airfoil device (10) closely conforms to the wing's airfoil geometry (e.g., low camber, sharp leading edge) when the lift-enhancing chamber (30) and the deicing chambers (32) are in a deflated condition. The lift-enhancing chamber (30) can be inflated during take-off and landing to provide a high chamber and less sharp airfoil geometry. If ice accumulates on the wing (14) during high speed flight, the deicing chambers (32) can be repeatedly inflated/deflated for ice removal purposes.
