A mathematical model of a tilt-wing aircraft for piloted simulation [PDF]
A mathematical model of a tilt-wing aircraft that was used in a piloted, six-degree-of-freedom flight simulation application is described. Two types of control systems developed for the math model are discussed: a conventional, programmed-flap wing-tilt ...

Fast control allocation algorithm for tilt-rotor VTOL aircraft
Control algorithms initially developed for tilt-wing vertical take-off and landing (VTOL) aircraft are adapted to the tilt-rotor design. The main difference between the two types of planes is the more complicated interaction between propellers and wings in the tilt-rotor design.

Flight Flutter Testing of Rotary Wing Aircraft Using a Control System Oscillation Technique [PDF]
A flight flutter testing technique is described in which the rotor controls are oscillated by series actuators to excite the rotor and airframe modes of interest, which are then allowed to decay.
