Three-Dimensional Flight Envelope for V/STOL Aircraft with Multiple Flight Modes
Aerospace, 2022 Vertical or short take-off and landing (V/STOL) aircraft generally have three flight modes, namely, vertical take-off and landing (VTOL), conversion, and cruise, according to the variable angle of propulsion direction to the fuselage axis.

Whirl Flutter Suppression of Tiltrotor Aircraft Using Actively Controlled Aileron
Aerospace, 2022 Whirl flutter of a tiltrotor aircraft is a complex aeroelastic phenomenon and it can result in catastrophic consequences. The deflection of an aileron mounted on a wing has the potential to solve this fatal problem.
