Faster-than-realtime inverse simulation method for tiltrotor handling qualities investigation
نویسندگان
چکیده
The tiltrotor aircraft has unique flight dynamics characteristics because of the extensive aerodynamic interference and control strategy. Inverse simulation offers an opportunity to study a vehicle's performance during manoeuvring flights. In this paper, improved inverse method is developed with Automatic Differentiation (AD) approach embedded in code based on verified model aircraft. AD algorithm would accelerate computational rate process make it achieve faster-than-realtime capability. Then, XV-15 tiltrotor's inputs states encountered pop-up manoeuvre are investigated using AD-augmented method, real-time capability also evaluated. results indicate that proposed guarantees both accuracy calculation performance. Lastly, manoeuvrability assessed by executing different settings. envelope involving velocity nacelle incidence angle calculated safety region manoeuvre.
