Dust Supply for GTE
This system allows supplying a predetermined amount of bulk material that is sprayed in the delivery pipe. Control of the mass of the bulk material is carried out by measuring the portion before supplying the product. This stand is prepared for use in harsh climatic conditions, control and measuring cabinets are protected by IP67, as well as equipped with a microclimate system for the best operation of equipment. 16 -1160 g/min error 1 %
Hydraulic Manifold Test Rig
The total capacity of the pumping unit is 95.5 kW. A separate high-pressure line (from 10 to 400 bar with a maximum flow rate of not more than 4.7 l / min). The main line (up to 210 bar at a flow rate of not more than 180 l/min, up to 350 bar at a flow rate not exceeding 110 l/min). Line of pilot pressure with the possibility of pressure regulation (manually) from 10 to 350 bar. A separate cooling and filtration circuit.
Hydraulic Valve Testing
The test rig is designed for testing hydraulic distribution units according to the algorithm specified in the technical documentation of the unit with control of the tightness of the channels of the distribution block. The stand provides carrying out of resource tests, check of internal and external tightness, measurement of characteristics of manifold channels (expense, pressure, expense-difference characteristics).
Test Control Panel
The complex 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 cases. The system is designed taking into account the possibilities of manual control and testing, while the safety parameters are constantly monitored by the real-time controller.
Turbine Blade Channel Test Rig
Designed to investigate the flow of fluid in the nozzle interlop channel. In the tank-receiver, a vacuum is created and through the inlet device air is sucked in and flows around the blades. Multiple perforation on the walls of the blade crown allows checking the pressure at the necessary points. The data are processed on the instrumentation and are displayed in a tabular and graphical form for analysis. Investigation of the flow of interblade channels 128 channels
Tests of the Dampers
The rig is designed to perform reciprocating motion at a specified speed up to a distance of 25 mm from the neutral position and the rotation of the level. Measuring ranges: Distance, mm 0..50; Speed, mm/s 0..130; Effort, kgf 0..1000
The control system of the shaker (hydraulic and electrodynamic) provides the ability to test the random vibration, in case of multiple excitation when the impact of seismic effects. Hydraulic shakers provide low-frequency region of large buoyancy force and large displacement. There are vertical and horizontal vibration stands and multi-axis platforms. Multi-axis shaker – the movable platform, the hexapod type, with hydraulic actuators is six -coordinate system micropositioning, working on the principle of parallel kinematics. The Stewart platform allows loading the object’s acceleration as feedback, and move for a different kind of training and simulation motion. New design of slip table Controllers for hydraulic and electro-dynamic shakers Frequency up 500 Hz

Motion Control System
Architecture of control systems is a reliable platform FPGA technology Time Sensitive Network that allows building distributed systems with synchronization dynamic signals. This technology allows unifying the test database and have current information on the status of testing and diagnostics equipment. An important advantage of the modular structure is the ability to move from laying electrical harnesses and positioning main units of test equipment in a convenient layout. Used classical and adaptive controllers allow you to play harmonic and random signals of loads with high accuracy.
