Abstract: Within examples, remotely controlled and thermally managed systems for actuation of components in a wind tunnel model are described. A wind tunnel test environment may provide ambient to cryogenic temperature conditions to reproduce aerodynamic flight Reynolds number conditions. Example systems comprise a modular test assembly mounted on a test component, and the test component includes at least one movable surface and is configured for placement in the wind tunnel. An actuator is included within the modular test assembly and coupled to the at least one movable surface of the test component, and a temperature sensor is included to provide temperature of an exterior of the modular test assembly. In addition, a controller is in communication with the actuator and the temperature sensor, and is configured to remotely cause the actuator to move the at least one movable surface through a range of motion.

Abstract: Improved miniature trailing edge effectors for aerodynamic control are provided. Three types of devices having aerodynamic housings integrated to the trailing edge of an aerodynamic shape are presented, which vary in details of how the control surface can move. A bucket type device has a control surface which is the back part of a C-shaped member having two arms connected by the back section. The C-shaped section is attached to a housing at the ends of the arms, and is rotatable about an axis parallel to the wing trailing edge to provide up, down and neutral states. A flip-up type device has a control surface which rotates about an axis parallel to the wing trailing edge to provide up, down, neutral and brake states. A rotating type device has a control surface which rotates about an axis parallel to the chord line to provide up, down and neutral states.
