Hydraulics is a technology for very strong pressure generation as well as for automation. On Mars it is very useful, since it can be produced and maintained with simple means.

Use cases in automation

A hydraulic temperature control works without auxiliary power. The principle is based upon the thermodynamic change of volume due to changes in temperature. A vessel filled with hydraulic oil produces an increasing pressure when temperature is rising. The pressure is used to move a piston, connected to a valve.

Use cases for fluid power

  • The tools of digging machines are moved by hydraulic power.
  • Heavy hatches can be locked by hydraulics.
  • Brakes in cars are usually hydraulic.
