Ball Screw Actuator Test Stand Model D39150
This test stand is designed for carrying out test procedures on aircraft ball screw actuators. The fixture on the left is for backlash testing while the fixture and console on the right are used for operational testing. A hydraulic motor and servo valve drive the input to the actuator, while a cylinder and servo valve apply either tensile or compressive load. A separate power pack is located behind the main test fixture.
