design of a ride quality augmentation system for future business jets

business jets manufacturers normally compete based on options and amenities they offer to comfort their potential passengers and crew. we expect future business jet to have long-range capabilities together with capabilities for short takeoff and landing; ability for formation flights and features like bathing. this work concentrates on the latter as we show a well-designed stability augmentation system (sas) could support passengers to take showers while having no harness. preliminary investigations suggest that potential business jet passengers enjoy being able to take showers in the last 60 minutes of flight; that is before landing. however, the biggest challenge is to develop a sas that works with the same quality throughout the whole cruising leg of the mission. in this work, the aircraft under investigation is debiz-2017 which is designed based on aiaa 2017 design competition rules; and the main contribution of this work is rcs design of it. dryden turbulence model has been employed to evaluate the aircraft ride quality system. further investigations might be necessary for other classes of turbulence.
