Abstract: An airborne vehicle having a body section; a main wing extending from the body section configured to generate aerodynamic lift, the main wing having one or more main wing control surfaces; and a tail assembly extending from the body section aft of the main wing. The tail assembly having a first tail member and a second tail member substantially parallel to each other. The first tail member having one or more control surfaces and the second tail member having one or more flap surfaces selectively deployable between a retracted position and an extended position. The flap surfaces being configured to increase a surface area and/or camber of the second tail member in the extended position.

Abstract: An exemplary flow control assembly includes, among other things, shutters each having at least one aperture. The shutters are configured to move back and forth between a first position and a second position to influence a flow through the at least one aperture. A flow control method includes, among other things, moving a shutters back and forth between a first position and a second position. The first position permits more flow through at least one aperture within each of the shutters than the second position.
