A test fixture was designed to apply this load to the speed brake through use of hydraulic cylinders. The design was used to generate component drawings prior to fabricating the fixture in MERC’s prototype shop. The system features fully integrated controls for automated testing of the speed brakes. The system is currently employed by the Air Force for screening speed brakes. Speed Brake Test System Prototype Speed Brake Test System Model MERC was tasked by the U.S. Air Force to develop a proof test for the F-15 Speed Brake. Existing non-destructive inspection focused on ultrasonic methods for identification of voids or disbonds in the composite part. For this project, a load-based test was desired to prove speed brake performance.
