Abstract
Loads from the propeller-gearbox-engine assembly are transferred to an airframe directly, without concentrated internal structure. In preferred embodiments this is accomplished using a lightweight, structurally efficient hub and gearbox that transfer their rotor loads directly to the nacelle OML (Out Mold Line) monocoque. By keeping the load path direct and at the largest diameter, the structure achieves higher stiffness and strength efficiency than conventional point loaded internal frames.
