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.
Claims7
A winglet airfoil venting system comprising:
- a winglet airfoil having upper and lower airfoil surfaces defining leading and trailing edges, and a planar trailing edge surface joining the trailing edges of the upper and lower airfoil surfaces;
- an internal channel adapted to being fluid-connected to an onboard aircraft system which in use requires air to be exhausted;
- and
- a series of venting apertures fluid-connected to the internal channel, the venting apertures being formed in and linearly aligned along at least a portion of the planar trailing edge surface of the winglet airfoil, wherein
- exhaust air from the onboard aircraft system is discharged rearwardly from the trailing edge surface of the winglet airfoil through the linearly aligned venting apertures.

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