METHOD AND SYSTEM FOR MEASURING TORQUE IN A TILTROTOR AIRCRAFT |
| 摘要 |
A method for calculating torque through a rotor mast of a propulsion system of a tiltrotor aircraft includes receiving the torque being applied through a quill shaft of the rotorcraft. The quill shaft is located between a fixed gearbox and a spindle gearbox, and the spindle gearbox is rotable about a conversion access. The torque through the rotor mast is determined by using the torque through the quill shaft and the efficiency loss value between the quill shaft and the rotor mast. |

1. A propulsion system for a tiltrotor aircraft, the propulsion system comprising:
an engine disposed at a fixed location relative to a wing member; a fixed gearbox; a spindle gearbox that is rotatable about a conversion axis; a rotor mast rotably coupled to the spindle gearbox; a quill shaft providing torque transfer between the fixed gearbox and the spindle gearbox; and a torque measuring system associated with the quill shaft comprising:
a computer system configured to calculate the torque value through the quill shaft. |
