A research excitation flight system was recently flight tested at NASA's Drine Flight Research Facility. A NASA F-16 XLR craft served as a test bed. This excited is unique because it is a self-contained lightweight excitation system which can easily be strapped onto a variety of aircraft. It is intended to be used in flight flight testing to help improve data quality and flight test efficiency. The system consists of a fixed vein with a rotating slotted cylinder at the trailing edge. The slotted cylinder rotates and the flow is ultimately deflected upward and downward. This results in a periodic lift force which is imparted to the aircraft at twice the cylinder's rotational frequency. The exciter vein is controlled by the pilot in the back seat of the X-16 XLR craft who sets the parameters for the test. Data is telemetry to the spectral analysis facility where it is monitored in real time. Here, response from the wing tips are monitored to find frequency and damping trends as functions of Mach number and dynamic pressure. The wing can be seen responding to the exciter vein's input, souping from 5 to 35 hertz. Data is analyzed on the computer showing the aircraft's natural frequencies. Test points were taken between Mach 0.6 and Mach 1.7 at an altitude of 30,000 feet. The variables in the different frequency sweeps were linear all-agrithmic sweeps, brain time length, brain force amplitude, and dwelling on a certain frequency. This exciter system has shown it can provide high quality data and improve flight test efficiency with minimal interface to aircraft systems. Future testing will continue to provide insight into using this system as a safer, more effective flight flutter testing system for today's flight research.
