Anti-roll thrust system for hydrogen powered vehicles
A thruster system is provided for a vehicle that can be used to reduce the roll propensity of a motor vehicle. The system utilizes a control system and multiple sets of thrusters which are strategically placed upon the vehicle. The control system is provided for detecting a potential roll condition and activates selected ones of the thrusters to produce a necessary thrust force for counteracting roll forces. The thrusters are connected to an on-board pressurized gas source that generates the anti-roll thrust force.
