Systems and methods are provided for an irreversible clutch to prevent back-drive. The irreversible clutch may transfer torque and/or rotation received at a first end to a second end, but may not transfer torque and/or rotation received at the second end to the first end. The irreversible clutch may prevent unintended adjustment of one or more rudder pedals and/or a rudder pedal assembly.

1. An apparatus comprising: a position adjustment and control system comprising a rudder pedal position adjuster and configured to receive an adjustment command from a user and provide an adjuster output responsive to receiving the adjustment command; andan irreversible clutch comprising: an input end coupled to the position adjustment and control system and configured to receive the adjuster output, andan output end, wherein the irreversible clutch is configured to transfer the adjuster output received at the input end to the output end as a clutch output, and wherein the irreversible clutch is further configured to receive a back-drive input at the output end and prevent a transfer of the back-drive input received at the output end to the input end. 2. The apparatus of claim 1, further comprising: an adjustable rudder pedal assembly comprising a pedal, coupled to the output end of the irreversible clutch, and configured to receive the clutch output and, responsive to the clutch output, adjust a position of the pedal. 3. The apparatus of claim 2, further comprising an adjustment shaft disposed between the irreversible clutch and the adjustable rudder pedal assembly and comprising a first end coupled to the output end of the irreversible clutch and a second end coupled to the adjustable rudder pedal assembly and configured to transfer the clutch output to the adjustable rudder pedal assembly. 4. The apparatus of claim 3, wherein the adjustment shaft is a flexible shaft. 5. The apparatus of claim 2, wherein the adjustable rudder pedal assembly comprises a rudder pedal jackshaft, the rudder pedal jackshaft comprises an adjustment screw, and the position of the pedal is adjusted by rotating the adjustment screw responsive to receiving the clutch output. 6. The apparatus of claim 5, wherein the adjustable rudder pedal assembly further comprises a plurality of pedals and wherein receiving the back-drive input comprises rotation of the output end responsive to operation of the pedals. 7. The apparatus of claim 6, wherein the adjustable rudder pedal assembly comprises two pedals and the operation of the pedals comprises concurrent operation of the two pedals. 8. The apparatus of claim 1, wherein the irreversible clutch further comprises: a plurality of bearings, wherein the input end comprises a first input end configured to receive the adjuster output and a second input end comprising a plurality of input end teeth, and the output end comprises an outer area configured to couple to the plurality of bearings and a plurality of slots and/or cutouts configured to receive the plurality of input end teeth; anda clutch housing comprising an inner housing configured to receive the plurality of bearings. 9. The apparatus of claim 8, wherein the position adjustment and control system further comprises a controller configured to receive the adjustment command and provide a mechanical adjuster output to the rudder pedal position adjuster. 10. The apparatus of claim 8, further comprising: an intermediate connector comprising a plurality of intermediate teeth and a plurality of intermediate slots and/or cutouts configured to couple to the plurality of input end teeth, wherein the plurality of bearings are disposed between the plurality of intermediate teeth. 11. The apparatus of claim 8, wherein the input end and the output end are configured to rotate around a centerline, and the outer area is configured to be disposed closer to the centerline than a center of mass of at least one of the bearings. 12. The apparatus of claim 1, further comprising an adjustment shaft disposed between the position adjustment and control system and the irreversible clutch and comprising a first end coupled to the position adjustment and control system and a second end coupled to the input end of the irreversible clutch and configured to transfer the adjuster output to the input end. 13. The apparatus of claim 1, wherein the rudder pedal position adjuster comprises a crank configured to receive the adjustment command and operate an adjuster drive responsive to receiving the adjustment command and be switched between an unlocked position configured to receive the adjustment command and a locked position configured to prevent movement of the adjuster drive, wherein the position adjustment and control system is configured to rotate the adjuster drive to rotate the input end, and wherein the irreversible clutch is configured to transfer the adjuster output to the output end by rotating the output end. 14. An aircraft comprising the apparatus of claim 2, wherein the aircraft comprises: a fuselage;a wing; anda rudder, wherein a configuration of at least a portion of the rudder is controlled by the adjustable rudder pedal assembly. 15. A method of assembling the apparatus of claim 2, the method comprising: disposing the irreversible clutch between the rudder pedal position adjuster and the adjustable rudder pedal assembly;coupling the irreversible clutch to the rudder pedal position adjuster; andcoupling the irreversible clutch to the adjustable rudder pedal assembly. 16. A method of operating the apparatus of claim 1, the method comprising: operating an adjustable rudder pedal assembly;receiving the back-drive input with the output end of the irreversible clutch responsive to operation of the adjustable rudder pedal assembly; andnot transferring the back-drive input to the input end of the irreversible clutch. 17. The method of claim 16, wherein not transferring the back-drive input comprises: transferring torque with the output end;receiving the torque with a plurality of bearings;pushing the plurality of bearings into an inner wall of a housing; andpreventing, responsive to the pushing of the plurality of bearings, movement of the plurality of bearings. 18. The method of claim 16, wherein the adjustable rudder pedal assembly comprises a plurality of pedals and operating the adjustable rudder pedal assembly comprises concurrently operating the plurality of pedals. 19. The method of claim 16, further comprising: operating the rudder pedal position adjuster;providing the adjuster output responsive to operating the rudder pedal position adjuster; andtransferring the adjuster output with the irreversible clutch to adjust a position of a pedal of the adjustable rudder pedal assembly. 20. The method of claim 19, wherein transferring the adjuster output comprises: receiving the adjuster output with the input end of the irreversible clutch;outputting the clutch output with the output end of the irreversible clutch responsive to receiving the adjuster output with the input end; andreceiving the clutch output with the adjustable rudder pedal assembly.
