  • Real Time Aircraft Stress Monitoring System
    Publication number: 20180099761
    Abstract: A method and apparatus for an aircraft monitoring system. The aircraft monitoring system comprises targets associated with the wing of the aircraft, a camera system and a monitor. The camera system is configured to generate images of the targets on the wing during operation of the aircraft. The monitor is configured to measure movement of the targets using images, enabling identifying wing movement.

  • Remotely controlled and thermally managed system for actuation of components in a wind tunnel model
    Patent number: 9677968
    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.
