Abstract: A method for forming composite components includes disposing composite laminate over a mandrel. The method further includes infusing the composite laminate with a resin. A gelation of the infused resin is caused by applying a first environmental condition to the composite laminate and mandrel. At least a portion of the mandrel is deformed by applying a second environmental condition to the composite laminate and mandrel. The method further includes forming a composite structure by curing the composite laminate infused with resin. The deformed mandrel is removed from the composite structure after forming the composite structure.

Abstract: An aircraft rotor assembly has a yoke defining a plurality of bearing pockets. Each bearing pocket houses an axisymmetric elastomeric spherical bearing at least partially therein. The axisymmetric elastomeric spherical bearings comprise flap, lead-lag, and pitch hinges for rotor blades coupled thereto. The rotor blades maintain a first in-lane frequency of less than 1/rev through the use of damper assemblies coupled between adjacent blades.
