    Abstract
  • The nonlinear flight dynamics model of tiltrotor aircraft was developed by considering the influence of rotor wake on wing, horizontal stabilizer and vertical stabilizer. Taking the tiltrotor XV15 for an instance, by simplifying the hovering model, trim result of hovering was easily calculated. Then, based on the hovering solution, using forward velocity and nacelle conversion angle as continuation parameters, trim calculations of helicopter mode, conversion mode and airplane mode were accomplished by numerical continuation method. Stability was also analyzed based on the trim results. Calculated results showed that, numerical continuation method can calculate the trim solution without being limited by the initial value; the continuation method can calculate the trim solution in the whole conversion envelope and provide a global analysis.
