Abstract:

This paper presents a time-domain approach for identification of longitudinal dynamics of single rotor model helicopter. A frequency sweep excitation input signal is applied for hover flying mode using widely used for space state linearized model. A fully automated programmed flight test method provides high quality flight data for system identification using the computer controlled flight simulator X-plane©. The flight test data were recorded, analyzed and reduced using the SIDPAC (System Identification Programs for Air Craft) toolbox for MATLAB resulting in an aerodynamic model of single rotor helicopter. Finally, the identified model of helicopter is validated on Raptor 30-class model helicopter at hovering showing the reliability of the proposed approach.
