They do that in other places.

As I heard the tale, on the Standard Missile, they don't recirculate the hydraulic fluid, they just spit out as the missile flies. It's a wonderful engineering solution.

And on the Falcon 9, the hydrocarbon fuel is used as hydraulic fluid, then just dumped back into the fuel tank.

  • And the SR-71 uses its fuel as coolant.
