Comparison between Gimballed and Hingeless Tiltrotor Whirl Flutter Stability with Multibody Dynamics Analyses

Proceedings of the Vertical Flight Society 80th Annual Forum
The tiltrotor whirl flutter stability of a gimballed hub and a hingeless hub are investigated using multibody dynamics simulations. A semi-span wind tunnel tiltrotor model are developed using the multibody dynamics code: Dymore.

AEROMECHANICS MODELLING OF TILTROTOR AIRCRAFT

2019
A numerical investigation into the effects of aerodynamic interaction modelling for tiltrotor aircraft is undertaken. The study compares a baseline case, with no interaction accounted for, with those that include the download on the wing and the rotor and wing wakes at the empennage against literature models.

Collective Bounce Problems on Tiltrotors

2016
The basic mechanism of the collective bounce phenomenon on tiltrotors is discussed. This phenomenon may arise if the pilot’s biomechanics interact with the airframe elastic modes, in particular with the 1st Symmetric Wing Bending (SWB) mode. A simplified aeroelastic tiltrotor model, able to capture the aircraft heave motion and the low–frequency out-of

Hybrid Locomotive Behaviors for an Amphibious Fixed-Wing / VTOL Tiltrotor UAV

International Conference on Unmanned Aircraft Systems
The theory and implementation of a set of alternate auxiliary locomotion modes are presented for an amphibious fixed-wing VTOL UAV. In real-world conditions and unstructured environments, the ability for the vehicle to employ alternative modes of ...
