Slidable divergent trailing edge device
First Claim

1. An apparatus comprising:
- a wing, the wing including;
an upper surface;
a lower surface opposite the upper surface;
a trailing edge;
a compartment defined between the upper surface and the lower surface near the trailing edge; and
an opening for the compartment defined in the lower surface, the opening spaced apart from the trailing edge such that a portion of the lower surface is disposed between the opening and the trailing edge; and
a divergent trailing edge (DTE) panel slidably disposed within the compartment, the DTE panel slideable between (1) a stowed position in which the DTE panel is disposed within the compartment and (2) a deployed position in which the DTE panel extends through the opening and below the portion of the lower surface between the opening and the trailing edge, the DTE panel increasing lift over drag of the wing when in the deployed position.

Abstract
A wing includes a trailing edge, and a divergent trailing edge device slideable along an aft surface of the trailing edge between a stowed position and a fully deployed position. The trailing edge device is located entirely within the trailing edge when stowed, and it increases lift over drag of the wing when deployed.

15. An aircraft comprising:
-
a wing including a moveable flight control surface having a trailing edge, a compartment defined between an upper surface and a lower surface of the moveable flight control surface, an opening for the compartment defined in the lower surface and spaced apart from the trailing edge such that a portion of the lower surface is disposed between the opening and the trailing edge; a divergent trailing edge (DTE) panel disposed within the compartment, the DTE panel slideable between (1) a stowed position in which the DTE panel is disposed within the compartment and (2) a deployed position in which the DTE panel extends from the compartment and is disposed below the moveable flight control surface; and an actuator to control the DTE panel independently of the moveable flight control surface. - View Dependent Claims (16)

17. A method comprising:
sliding a divergent trailing edge (DTE) panel through a compartment defined in an aircraft wing and through an opening in a lower surface of the wing to reduce lift over drag (L/D) of the wing, the compartment defined between an upper surface and the lower surface of the wing, the opening defined in the lower surface and spaced apart from a trailing edge of the wing such that a portion of the lower surface is disposed between the opening and the trailing edge. - View Dependent Claims (18, 19)
