Shafts in order of strength: Wood, Stone, Steel, Diamond, Bedrock

Shafts are used to transmit power.

Rotarycraft Handbook DescriptionEdit

"The most basic power-transmission device is the shaft.  Nothing fancy, just carries the power from one place to another, with no changes to either the torque or the speed.  Pay attention, though, to the direction to avoid headaches.  Different materials of shaft have different strengths and thus different limits on maximum torque and speed." 

Shaft StrengthEdit

This table shows, at full power, if an engine will overload a shaft.

Wood Shaft Stone Shaft Steel Shaft Diamond Shaft Bedrock Shaft
DC Electric Engine No No No No No
Wind Turbine No No No No No
Steam Engine No No No No No
Gasoline Engine No No No No No
AC Electric Engine Yes No No No No
Performance Engine Yes No No No No
Hydrokinetic Engine Yes Yes Yes No No
Microturbine Yes Yes Yes No No
Gas Turbine Yes Yes Yes No No

Shaft LimitsEdit

Wood Shaft

278 Nm at 3,577 rad/s

Stone Shaft

958 Nm at 11,561 rad/s
Steel Shaft 5560 Nm at 57,005 rad/s
Diamond Shaft 69508 Nm at 4,121,484 rad/s
Bedrock Shaft < None >

Tips & TricksEdit

  • While the hydrokinetic engine can overload the torque of everything below diamond, a few gearboxes can allow for the use of a steel or even possibly a stone shaft.  Likewise for speed in the microturbine and gas turbine. (This is no longer true, see: Gearbox)
  • Wood shafts are flammable.
  • Wood shafts are very vulnerable to explosions; bedrock ones are impervious.
