Aircraft actuators and hydraulic units
Hydromash JSC performs development, manufacturing, testing and maintenance of a wide range of hydraulic and pneumatic units to be installed on aircraft and helicopters.
- Hydraulic/pneumatic actuators for systems with operating pressure up to 35 MPa (350 kgf/cm3):
-
- extension and retraction of landing gears of aircraft and helicopters
- aircraft takeoff and landing mechanics
- aircraft flight control
- opening and closing of aircraft section doors
- retraction and extension of other aircraft elements
Design variations of actuators:
- lockless
- lockless with braking at the end of rod stroke (using, if necessary, anti-g valves)
- with integrated mechanical lock in retracted and/or extended position of rod
- with integrated mechanical lock and drive of locked position signaling system
- with integrated mechanical lock and installed mechanism of locked position signaling system
- with integrated mechanical lock and braking at the end of rod stroke
- with installed hydraulic lock
- with installed emergency valve
- with installed hydraulic lock and emergency valve
- aircraft attachment fitting with swivel bearings, including self-lubricating bearings, as well as cardan joint attachment, including hydraulic fluid routing.
- Hydraulic units:
- steering dampers
Hydraulic units of valve type with mechanical drive and feedback, designed for distribution of hydraulic fluid between working sections of load-bearing actuators of steering units in steering mode, and for building hydraulic resistance during hydraulic fluid streaming from one actuator section to another in damping mode.
- hydraulic shimmy dampers
Designed for nose landing gear shimmy type vibration prevention
- non-flow dampers
- lifting dampers
- stabilizing dampers
- special dampers
Designed for aircraft flight control vibration prevention
- hydraulic compensators
- aircraft and helicopter hydraulic system units
- dashpots
- metering units.
Civil hydraulic actuators
Apart from aircraft specialization Hydromash JSC designs and manufactures hydraulic actuators used as load-bearing elements of hydraulic systems of various road-building equipment (excavators, loaders, tractors etc.), agricultural equipment, combined navigation vessels, mining equipment, special-purpose equipment etc.
Design of hydraulic actuators includes:
- different types of damping, which shuts outs overload of equipment elements
- modern high-quality durable seals, manufactured on the basis of polyester thermoplast and composites from the leading companies of Germany and Russia.
Quality of hydraulic actuators corresponds to the strictest requirements due to application of new technologies and materials, computer design and CNC machine manufacturing, testing equipment and highly efficient monitoring and inspection system.
Hydromash JSC performs serial production and favors orders for the following equipment:
- cylinders of dia. 65 - 220 mm;
- rods of dia. 50 - 160 mm, and length up to 2000 mm.
We seriously take into account market requirements and our customers' demands.
