Abstract:
An active balancer for dynamically balancing a rotating machine is provided. The active balancer has a balancer body (25) which rotates with the rotating machine and at least one controllable position counter weight (26) having a real-time adjustable position relative to the balancer body and the rotating machine in order to produce an actively adjustable controllable counter weight balance for dynamically balancing the rotating machine. The active balancer includes a spring (28) with the balancer body mounted to the rotating machine through the spring wherein the balancer body mass resonates on the spring with a torsional vibration canceling frequency which cancels a torsional vibration of the rotating machine.
Abstract:
Helicopter reduced vibration axial support struts and aircraft suspension system are disclosed with at least one vibration controlling fluid containing strut. The powered struts include an outer rigid housing containing an inner rigid member and first and second variable volume fluid chambers. Fluid pressure differentials are created between the first and second variable volume fluid chambers to control motion between the strut ends. The powered fluid containing struts, support isolators, suspension systems, and methods of operation provide reduced helicopter aircraft vibrations.
