Issued:2008-08-19
Filed:2005-05-31
Application No:11140762
Examined by:Swiatek; Rob

A gearbox of a high speed compound rotary-wing aircraft includes a main module, an input module and a translational thrust module. The input module receives power from the engines to drive a dual, contra-rotating, coaxial main rotor system and a translational thrust system which provides significant translational thrust generally parallel to an aircraft longitudinal axis. Each of a multiple of engine drives the input module such that power is distributed to the main module and the translational thrust module. The gearbox provides a lightweight solution, since each module need only transmit a required fraction of available engines power.
