Abstract

Flight tests of TR-60 in order to evaluate the control performance in helicopter, conversion and airplane mode were completed. In order to reduce the development risk and schedule, single channel out of the dual flight control computer of Smart UAV (TR-100) was used without the other modification. Therefore the operational flight program (OFP) had the minimum changes only on control laws. Even though similar flight control system was applied to the scaled tilt-rotor aircraft, named as TR-60, many unexpected anomalies occurred during flight test from hover to airplane mode mainly due to the different bandwidth between TR-100 and TR-60. This paper presented the details of flight test data and anomalies which occurred during flight test of TR-60 as well as the trouble shooting results.
