Landing Gear Testing
A rig provides a simulation of the aerodynamic moment, due to three axial loading. The test helps to obtain the following parameters:
- a load applied to the object and measured by force sensors,
- strain-gauge measurement at 30 points,
- temperature measurement in the axes of a landing gear rotation.
The layout of this rig allows quick adjusting the rig to other types of landing gear.
Loading accuracy < 4%

Hydraulic Manifold Test Rig
The test rig is designed for testing hydraulic manifolds according to the algorithm specified in the technical documentation of the item. The test carries out durability tests, check of internal and external leakproof, measurement of characteristics of hydraulic manifold channels (flow, pressure, relationship between pressure drop and flow rate).
Hydraulic Valve Testing
The rig provides different modes of hydraulic equipment test (hydraulic directional valves, servo equipment, pressure control valves and release valves).
Design of the rig allows easy changing of the hydraulic scheme to meet the task. User-friendly interface of the software performes all the necessary measurements in both manual and automatic modes.
Test Control Panel
The equipment contains a real-time controller and an industrial computer. All management operations are performed on the real-time operating system. At the same time, the flexibility of the PC software makes it possible to adapt the interface to the requirements of the tasks. The system is designed considering the possibilities of manual control and testing, while the safety parameters are constantly monitored by the real-time controller.
Nozzle Test Rig
Designed to investigate the fluid flow in the nozzle interblade channels. In the tank-receiver a vacuum is created and air is sucked through the inlet device in and flows over the blades. Multiple perforation of the nozzle surface allows checking the pressure at the necessary points. The data are processed and displayed in a tabular and graphical form for analysis.

The control system of the shaker (hydraulic and electrodynamic) performs the random vibration test to simulate the impact of seismic effects. Hydraulic shakers provide low-frequency vibration and large force. There are vertical and horizontal vibration rigs and multi-axis platforms. Multi-axis shaker is a movable platform of the hexapod type with hydraulic actuators This is a system of 6 degrees of freedom, working on the principle of parallel kinematics. The multi-axis platform allows loading the object with the help of acceleration as a feedback.

Motion Control System
Сontrol system is a reliable platform based on FPGA with Time Sensitive Network technology that allows building distributed systems synchronizing dynamic signals. This technology allows unifying the test database and obtain current information on the status of testing and of equipment diagnostics. An important advantage of the modular structure is the ability to move away from laying electrical harness towards placing main units of test equipment in a convenient layout. Used classical and adaptive controllers allow performing harmonic and random load signals with high accuracy.
