The conventional flywheel is often used for (1) energy storage (2) pulse absorption, and its internal characteristics are fixed so that ernergy absorption and release always manifest themselves as a speed increase during energy storage and a speed decrease during energy release. The present invention relates to the priciples and structure of variable-inertia flywheels which enable the control and adjustment of the relationship between energy storage and release, and speed; when flywheel is used speed rate change can be minimized due to moment change, and due to dynamic energy is in direct proportion to the square of inertia mass times speed, where if flywheel speed is defined as (2 -Rn) then dynamic energy stored in the flywheel is: <MATH> where, E: energy, ft lbf or J m: flywheel mass, lbm or kg gc: converting factor = 32.2 lbm FT/(lbf S<2>> = 1.0 kg/(N S<2>) R: gyration radius, ft or m n: rotation per second (r/min)/60 <IMAGE> |
