ABSTRACT:
A vibration isolation system for a passenger carrying helicopter with which the crew seats in the cockpit area and the floor in the passenger area are decoupled from the airframe thereby isolating the seats and floor from the airframe vibrations. In addition, the fuel tanks of the helicopter are isolated from the airframe so that a force feedback from the fuel tank to the airframe resulting from the changing fuel quantity is effectively eliminated. The system employs nodal isolators which both isolate (decouple) and support the particular structural mass in question.
