| description | Compared with similar helicopters, the autogyro has its unique advantages and has been widely applied in the civilian field. In order to provide theoretical reference for unmanned flight control of autogyro, the features, advantages and exiting problems of autogyro are analyzed thoroughly. Based on the variable speed of main rotor, propeller and airframe, the flight dynamic model of autogyro is built. The ELA-07AGRO is taken as an sample of autogyro, which is modeled and trimmed; and its stability is analyzed. Besides, the manipulation variables, Euler angles and flight modes are extracted from the flight test data and compared with the results of the calculation. The comparisons show that in the regular speed range, the longitudinal control of the sample autogyro needs to be pushed forward monotonously; the lateral control needs to be mildly pushed left monotonously; the rudder is turn to left; the throttle first decrease and then increase. As for the stability of flight modes, the spiral and Dutch-roll model is slowly divergent, and in the long/short period, phugoid, rotorspeed and roll subsidence modes are stable. It can be concluded that the sample autogyro has good stability. |
