Hydraulic actuators and pumps
Graviman,
There are several manufacturers of aircraft hydraulic actuators, depending upon what type you want. Hydraulic actuation systems can have linear or rotary outputs. They can be mechanically or electrically controlled. The hydraulic pressure can be generated by a remote EMAD or AMAD mounted mechanically driven pump, or by an electrically driven pump within a closed loop hydraulic circuit that is part of the actuator. You will also need to specify the operating characteristics, such as duty cycles, frequencies, actuation forces/travel/inertias, fault tolerance, etc.
It will be fairly easy to find an aircraft quality pump. Try Vickers (UK), Parker Hannifin, Bosch Rexroth, or Eaton. Finding an aircraft quality actuator will be more difficult, since these are usually made to order. Try Moog, Hamilton Sunstrand, Eaton, Claverham (UK), or Parker.
Hope that helps.
