Ground Support Equipment
The test rigs are designed to test the main and reserve hydraulic systems of an airplane/helicopter under airfield conditions. They have two independent hydraulic circuits. The test rig is mobile, equipped with a set of nodes, controls and measuring instruments, it can perform refuelling of the system.

Characteristics of airplane design:
  • Primary line working pressure 35 MPa
  • Flow rate 125 l/min per circuit
  • Working fluid Skydrol
  • Power 90 kW
  • Working fluid fineness 3 microns
  • Voltage - 3x380V
  • Air cooling
  • Operating temperature range - 0 ... 50 ° C
Characteristics of helicopter design:
  • Pressure 8 MPa
  • Flow rate 40 l/min per circuit
  • Working fluid FH51
  • Gas - nitrogen 
  • Tank 40 liters
  • Charging pressure 3 MPa
The test rig can be designed according to a simplified scheme directly connected to the airplane reservoir, without refuelling. 

  • 2 independent pressure circuits
  • Pressure 15 MPa
  • Working fluid FH51
  • Supply 40 l/min per circuit
  • Manual ergonomic control
