Landing Gear Testing
Landing Gear Test
The task was to create a landing gear test bench that provides different types of tests: static and dynamic tests with simulated aerodynamic moment.
With regard to the dynamic tests, it was necessary to consider the mutual effects of multi-coupling loading.
For the long-term fatigue tests, an adaptive interconnected loading control algorithm was applied that adjusts to the changes occurring in the rig during the tests. Steady-state error < 1%; transient error < 4%.

Landing gear lock testing
The solution is designed for static and re-static testing of retracted position locks of landing gear. Reconfigurable holding frame allows in the shortest time to modify the rig for a wide range of similar test objects. The reinforced structure is resistant to temperature fluctuations in the range of -50 ... +60 °С that allows using it in climatic chamber. The paint coating is resistant to aggressive hydraulic working fluids, including Skydrol.
