Comparison of Linear Flexible Aircraft Model Structures on Large Flexible Tiltrotor Aircraft

Journal of Aircraft, 2023
Structural modes for large aircraft occur at low frequencies and must be accounted for in the flight dynamics modeling and control system design process. An analysis is performed on various linear representations of flexible aircraft with an application to the lateral/directional flexible dynamic response of the notional Large Civil Tiltrotor (LCTR2 ...

Dynamics of Flexible Aircraft

2023
Explore the connections among aeroelasticity, flight dynamics, and control with an up-to-date multidisciplinary approach. New insights into the interaction between these fields, which is a distinctive feature of many modern aircraft designed for very high aerodynamic efficiency, are fully illustrated in this one-of-a-kind book.

Aircraft Control Based on Flexible Aircraft Dynamics

Journal of Aircraft, 2017
In this paper, the control law design for flexible aircraft is discussed. First, the traditional procedure of decoupling rigid-body and aeroelastic dynamics with low-pass and notch filters is addressed, with focus on controller performance as well as the resulting stability margin issues.

Ground Vibration Testing on Very Flexible Aircraft

AIAA Scitech 2020 Forum, 2020
As aircraft become more flexible in an effort to improve efficiency to reduce fuel consumption and operating costs and improve endurance, structural nonlinearities become more apparent. As a consequence, testing practices that are well established and mature for traditional, relatively rigid aircraft need to be re-examined.
