  • Barrel cam rudder pedal system
    Patent number: 9581226
    Abstract: A barrel cam rudder pedal system is provided. The system includes an outer housing with a chassis assembly carried by the outer housing. A barrel cam arrangement is rotationally mounted within an interior space of the chassis assembly. A pair of pedal assemblies is mechanically coupled to the barrel cam arrangement such that linear movement of either of the pair of pedal assemblies results in a rotation of the barrel cam arrangement about a central longitudinal axis defined by the barrel cam arrangement.
    Type: Grant

  • Line replaceable, fly-by-wire control column and control wheel assemblies with a centrally connected line replaceable disconnect and autopilot assembly
    Patent number: 9352824
    Abstract: A yoke for controlling the attitude of an aircraft is provided. The yoke includes a chassis, a pitch hub, a roll hub, a support column, a control wheel and a connection arrangement. The pitch hub rotatably mounts to the chassis. The roll hub rotatably mounts to the chassis for motion being generally parallel to the pitch hub. The support column attaches to the pitch hub for rotational motion with the pitch hub relative to the chassis. The control wheel pivotally attaches to the support column for rotational motion about a control wheel pivot axis being generally perpendicular to the pitch and roll hubs. The connection arrangement couples the control wheel to the roll hub and is configured to rotate the roll hub about the roll axis when the control wheel is rotated about the control wheel pivot axis. A system including interconnected yokes is also provided.
