Abstract: A fan blade support assembly for an aircraft is generally disclosed. The fan blade support assembly includes a fan assembly having a plurality of fan blades, a power shaft extending between the fan assembly and an engine of the aircraft, and a housing assembly positioned around the power shaft. The housing assembly includes a convergent housing and a sealing shroud. The convergent housing includes a cap, a base, and a middle portion extending therebetween. The base defines a first diameter, and the cap defines a second diameter less than the first diameter. The sealing shroud is positioned between the convergent housing and the power shaft. A gap is defined between the sealing shroud and the power shaft.

Abstract: An axially hyperstatic system softener for a transmission comprising a static component and a rotatable component mounted to each other by a double ball bearing having an outer race and an inner race includes first and second biasing elements in a rigid sleeve with the outer race disposed between the first and second biasing elements. The rotatable component includes two shafts splined together with the static component mounted to one of the shafts by the bearing double ball bearing. A shim between one of the biasing elements and the sleeve enables tuning the softener.
