An assembly (20) for an aerial vehicle includes an airframe (24) and a fluid circuit (128). The airframe (24) includes a body (110) and an airfoil (112) projecting out from the body (110). The airfoil (112) includes a first surface (122) and a first aperture (168) in the first surface (122). The fluid circuit (128) is configured to bleed gas from a gas turbine engine (22) mounted to the airframe (24) to provide control gas. The fluid circuit (128) is configured to selectively direct the control gas to the first aperture (168).
