The Adaptive Digital Automated Pilotage Technology (ADAPTTM) flight control software package aims to take advantage of redundant controls to improve safety, survivability, and performance for advanced rotorcraft. Vehicle Maneuver Optimization (VMO) is one component of the ADAPTTM architecture. VMO uses feedforward control to increase aircraft maneuverability. The VMO algorithm takes advantage of the control null space of over-actuated aircraft to optimize their quasi-steady trim. In this study, the system is applied to a coaxial compound helicopter and evaluated in piloted simulations at the NASA Ames Vertical Motion Simulator and at the Penn State Rotorcraft Simulator. Handling Qualities Ratings indicated that VMO enhanced handling qualities in aggressive MTEs involving turns, as seen in a Break Turn MTE and a customized Maximum Performance Turn MTE. Simulation results also showed that VMO achieved significant power reductions in these maneuvers. VMO was found to degrade handling qualities for some other MTEs, notably in some of the precision tracking MTEs and the High Speed Accel/Decel MTE. While VMO is not intended for use in precision tracking tasks, some improvements are warranted so that VMO can be used to maximize performance in accelerations without degradation in handling qualities. The benefits of VMO in turn maneuvers, both in terms of performance and handling qualities, are achievable in conjunction with both the inner- and outer-loop control laws of the coaxial compound helicopter.
