    Abstract: An apparatus includes a first shaft member including a first material and having a first shaft axis, a first distal end having a first diameter, and a first proximate end, and a second shaft member including a second material different from the first material, and having a second shaft axis, a second proximate end having a second diameter, and a second distal end. A joint permanently affixes the first distal end of the first shaft member to the second proximate end of the second shaft member such that the first shaft axis is aligned with the second shaft axis, where the first distal end substantially abuts the second proximate end, and wherein the first diameter is substantially identical to the second diameter. The second shaft member protrudes through a housing, the housing including a seal sealing against an outer diameter of the second shaft member.

    Abstract: A variable-speed gearbox for a tiltrotor with fixed engine and rotating proprotor includes an input shaft coupled to the respective fixed engine, an output shaft coupled to the respective proprotor; a high-speed clutch integrated into a high-speed gear train, the high-speed gear train having an input coupled to the input shaft and an output coupled to the output shaft; and a low-speed clutch integrated into a low-speed gear train, the low-speed gear train having an input coupled to the input shaft and an output coupled to the output shaft. The high-speed clutch and the low-speed clutch can be freewheeling clutches capable of disconnecting the output and the input of the respective gear train of the high and low-speed gear trains in an overrunning condition when the output rotates faster than the input of the respective gear train. The low-speed clutch can be permanently engaged. In accordance to some embodiments the variable-speed gearboxes may include an accessory drive.
