3 DOF Helicopter
Advanced flight dynamics concepts by extending control to three axes (travel, yaw and pitch)
The 3 DOF Helicopter experiment provides a bench top model of a Tandem rotor helicopter. It can be used to understand and develop control laws for a vehicle that has dynamics representative of a dual rotor rigid body helicopter, or any device with similar dynamics.
