A rotor system is disclosed for a reactive drive rotary wing aircraft. Apparatus and methods are disclosed for maintaining the rigidity of the rotor and eliminating play between flight controls and the rotor by mounting swashplate actuators to a flange rigidly secured to the mast. Methods are disclosed for modulating the temperature of oil pumped over one or more of the mast bearing, swashplate bearing, and spindle bearing. The temperature of air passively or actively drawn through rotor may also be modulated to maintain bearing temperature within a pred...


1. A rotor system comprising: a mast mounted to an airframe and defining a rotor axis;a hub rotatably mounted to the mast and rotatable with respect to the mast only about the rotor axis, the hub defining a hub cavity; anda plurality of blades mounted to the hub, blade of the plurality of blades defining a duct in fluid communication with the hub cavity, the blade duct being defined by a blade spar of the each blade, the blade spar extending through the hub and into the hub cavity and having a pitch horn secured thereto and positioned within the hub cavi...
