Abstract:
This paper presents the flight-testing method for system identification used during the LUA autonomous helicopter development and the computed on-axis dynamic model derived from the flight test data. The applied flight-testing method achieved excellent results with very low cross-control correlation, which was verified by comparing the SISO and MISO frequency response. A simple, yet accurate, on-axis dynamic model was derived for the hover condition using the higher-order hybrid model formulation, demonstrating that the vehicle response is dominated by the coupled rotor/fuselage dynamics. A short analysis of the LUA and similar size helicopters dynamic modes is completed, finding that their responses are dominated by the rotor dynamics, which might be a common trait among small-scale helicopters due to design choices in low-weight aircraft.
