  • That's just a big Storm Trooper helmet.

  • Is that why the bottom flap is slow, because it isn't mounted on a plane yet? Why would that be?

  • @thibaulthalpern weight

    

  • @thibaulthalpern Because its hooked up to a less powerful test pump.

  • @thibaulthalpern the top flap is being pulled by gravity and the lower flap has to work against it

  • The first run is slow because they're bleeding the air out of the hydraulics. Otherwise is just slower than normal because a plane's hydraulic system is capable of much more flow than the test stand.

  • @thibaulthalpern it just because normally a plane generates much more hydraulic pressure to make the reverse thrusters move than they can generate on the ground

  • @thibaulthalpern its running on a test stand hydraulics. the aircraft hydraulics pump out a MUCH high GPM

  • He is sow slow because the reverser doesn´t have enought hydraulic pressure to be faster. In the aircraft each engine or electrical hydraulic pumps will supply 3000 psi. It will be fast closing and opening.

  • Sometimes the hydraulic actuators are of different size to make them fit in the engine cowling. Also because ground test uses a less powerfull hydraulic pump than the engine driven pumps you may get this effect.

  • Pull of gravity maybe?
