This is a Universal Test Rig for conducting Performance Acceptance Tests (PAT) for all 5 actuators of a passenger aircraft landing gear. Designed and built by our in-house R&D team, the tests include Proof pressure and Static Test, Static load compression test, Static load tensile test, Dynamic leakage test, Antagonistic Test - Extension, Antagonistic Test - Retraction, Leakage Tests(including long duration testing), Dampening measurement for Aircraft Landing gear actuators etc.

This machine is capable of conducting 54 tests for all 5 actuators on a single Test Rig. It can apply pressures ranging from 0.5 bar to 1000 bar using the same power pack.

We follow an Engineer to Order(ETO) process and each machine will have its own unique features and capabilities. Hence, specifications like Max/Min length of actuator, Max External load at a certain pressure, max weight of actuator, Min/Max frequency of possible displacement, Highest testing pressure etc. varies with the End Customer requirements.

Following are some of the major tests that can be conducted on this system

  • Preliminary test
  • Proof pressure and Static Test
  • Static load compression test
  • Static load tensile test
  • Dynamic leakage test
  • Antagonistic Test - Extension
  • Antagonistic Test - Retraction
  • Speed measurement during Extension
  • Speed measurement during Retraction
  • Leakage tests
  • Dampening measurement
  • Cleanliness check
  • Delivery condition
  • Testing of Manifold assembly
  • Proof pressure test
  • Internal leakage Test
  • Long Duration Leakage Test
