Flight Mechanics Modeling of the New Configuration Tilt-rotor

Blog Article

The flight mechanical model of tilt-rotor UAV is the basis of designing flight control rate and analyzing flight characteristics.Based on the engineering reality, the nonlinear flight mechanics model of a new configuration tilt-rotor UAV is set up.Features and advantages of the new type rotor-craft are analyzed compared with the daddario ej10 traditional tilt-rotor.The flight dynamics models of helicopter mode, conversion mode and airplane mode are developed.

Based on the flight mechanics model, taking helicopter mode for example, trim and stability are analyzed for different flight speed.The calculate results show that, this configuration tilting rotor has good lateral and directional stability in cath kidston forget me not helicopter mode.The lateral and longitudinal coupling of helicopter hover mode is nearly little.
