20110277587 | Variable inertia flywheel - The variable inertia flywheel is a wheel on an axle with a toroidal hollow tubular rim that is completely filled with a fluid. The tubular rim contains one of more one-way valves that allow the fluid to pass in the opposite direction of rotation. When torque is applied to the axle the wheel accelerates but the fluid lags in acceleration. The wheel has two components of inertia, the solid material of wheel and the fluid. The fluid lag lowers the effective moment of inertia of the total system compared to a solid flywheel of the same mass. After a period of time the fluid acquires the same speed as the wheel. The one way valves close on deceleration. The wheel now operates as a solid flywheel of the same total mass to deliver energy to the load. | 11-17-2011 |
