Abstract
Airfoil venting systems are provided which include an airfoil (e.g., a winglet or an aircraft wing) having leading and trailing edges and an internal channel adapted to being fluid-connected to an on-board aircraft system which in use requires air to be exhausted. A series of venting apertures are positioned on at least a portion of the trailing edge of the airfoil and fluid-connected to the internal channel whereby air from the on-board aircraft system can be exhausted therethrough.
Claims11
An airfoil venting system comprising:
- an airfoil having leading and trailing edges,
- an internal channel adapted to being fluid-connected to an onboard aircraft system which in use requires air to be exhausted;
- and
- an aligned series of venting apertures formed in at least a portion of the trailing edge of the airfoil and fluid-connected to the internal channel, wherein
- exhaust air from the onboard aircraft system is discharged rearwardly from the trailing edge of the airfoil through the venting apertures.

An aircraft comprising:
- an onboard aircraft system which in use requires air to be exhausted;
- an airfoil having leading and trailing edges;
- and
- a venting system to vent exhaust air from the onboard aircraft system from the trailing edge of the airfoil, wherein the venting system comprises:
- (i) an channel internally provided in the airfoil which is fluid-connected to the onboard aircraft system to receive exhaust air therefrom;
- and
- (ii) an aligned series of venting apertures formed in at least a portion of the trailing edge of the airfoil and fluid-connected to the channel, wherein
- exhaust air from the onboard aircraft system is discharged rearwardly from the trailing edge of the airfoil through the venting apertures.
