摘要： A method (600) for forming composite components includes disposing (610) composite laminate over a mandrel. The method further includes infusing (620) the composite laminate with a resin. A gelation of the infused resin is caused by applying (630) a first environmental condition to the composite laminate and mandrel. At least a portion of the mandrel is deformed by applying (640) a second environmental condition to the composite laminate and mandrel. The method further includes forming (650) a composite structure by curing the composite laminate infused with resin. The deformed mandrel is removed (660) from the composite structure after forming the composite structure.

摘要： A ducted fan for a helicopter includes a transverse duct and a counter-torque device supported within the duct. The counter-torque device includes a rotor rotatably mounted within the duct and a stator fixedly mounted within the duct downstream from the rotor. The rotor includes a rotor hub having a rotor axis, and rotor blades extending from the hub. The Rotor blades have a modulated angular distribution about the rotor axis. The stator includes a stator hub, and a plurality of stator vanes distributed around the stator hub. The stator vanes are angularly modulated around the stator hub.
