Flight Dynamics Analytically-Derived Mathematical Model of Tiltrotor Aircraft: The development of an approachable tilt-rotor flight mechanics model, with clearly defined limitations, suitable for performance and piloted flight simulation

State-of-the-art tilt-rotor flight mechanics models appear to be inadequate in predicting the flight dynamics behavior across the entire flight envelope due to a lack of experimental data suggesting the need for more generic models. This paper presents a middle ground between model flexibility (genericity) and accuracy. For this purpose a...

Incremental nonlinear control applied to tiltrotor aircraft

Incremental nonlinear control is a promising control method that can be applied in controlling tasks that involve systems with highly nonlinear dynamics. Incremental nonlinear control is a feedback linearization method that requires less model knowledge than conventional Nonlinear Dynamic Inversion and is robust against model mismatches. This...

A Theoretical Approach for Analysing the Stability Characteristics of Tiltrotor Aircraft

Conceptual Design Optimization for Handling Qualities Applied to Tiltrotor Aircraft in Conversion Mode

A tiltrotor has the features of both a fixed-wing aircraft and a helicopter, thereby blending the vertical flight capabilities of helicopters with the speed, altitude, and range of fixed-wing aircraft. However, as an important aspect of piloted aircraft, the handling qualities of tiltrotor aircraft have not been studied extensively. This thesis...

Development of a quasi-linear parameter varying model for a tiltrotor aircraft

The research presented in this paper focuses on the development of a quasi-Linear Parameter Varying (qLPV) model for the XV-15 tiltrotor aircraft. The specific category of qLPV modeling technique, known as the model stitching technique, is employed to model the time-varying dynamics of XV-15 tiltrotor aircraft over the entire flight envelope....
