ABSTRACT:
A dampening system for a miniature high-speed turbojet engine provides single or multiple resilient mounting which includes a seal with an at least partially encapsulated spring for forward and aft bearings which mount a rotor shaft. The self-induced first engine order of the rotating rotor shaft is transmitted through the forward and aft bearing and is then absorbed in the resilient mountings. Dependable seal and vibration reduction is thereby provided irrespective of long term storage.
