Design of a Ride Quality Augmentation System for Future Business Jets

Business jets manufacturers normally compete based on the options and amenities they offer to comfort their potential passengers. We expect future business jets to have long-range capabilities together with abilities to take-off and land in shortest possible time and being able to enter a formation flight. When it comes to passenger comfort, features like bathing and physical exercise are very pleasing. This work concentrates on the latter part; as we show a well-designed Stability Augmentation System (SAS) could support passengers to take showers and exercise while having no harness. Such features, obviously, could not be available in all phases of flight and the major challenge is, therefore, to develop a SAS that works throughout the whole cruising phase of the mission. In this work, we demonstrate how a Ride-Quality- System (RQS) has been developed for DeBiz-2017 aircraft. The aircraft has been designed based on AIAA 2017 design competition rules. Dryden turbulence model has been employed to evaluate the aircraft RQS. Further investigations might be necessary to make the RQS as robust as possible.
