The Aluminium Fly Wheel measures 11.5cm in diameter with 2mm thickness, in a round silvery white aluminium disc, designed for science projects and Stirling engine builds requiring stronger rotational inertia than smaller flywheels. This aluminium flywheel is significantly larger than the 6.5cm variant covered separately — since rotational inertia scales with the square of the radius, this 11.5cm disc stores roughly three times the rotational energy of the smaller flywheel at the same 2mm thickness, making it the better choice where stronger flywheel effect is needed.
This aluminium fly wheel for stirling engine application is specifically sized for the larger flywheels that Stirling engines require — these low-torque heat engines depend on stored rotational momentum to carry the piston smoothly through dead-center points in the cycle where the engine itself produces no driving force, and an undersized flywheel causes the engine to stall at these points rather than completing the cycle.
This aluminium flywheel for projects does not list a specified center mounting hole — builders planning to fit this flywheel onto an engine or motor shaft should confirm the bore size or drill the center hole themselves to match their specific shaft diameter before assembly.
