IMPROVING EFFICIENCY REQUIRES INCREASING THE GAS TURBINE ROTOR SPEED. THE EXISTING TRANSMISSION CAN NOT PROVIDE THEM.

PRODUCT OF PROJECT

PROBLEM

THE PRODUCT OF THE PROJECT IS A HYBRID GAS-STATIC BEARINGS CONTROLLED WITH JET CONTROL SYSTEM. THE LACK OF PHYSICAL CONTACT BETWEEN THE SHAFT AND THE BEARING DUE TO GAS LUBRICATION SYSTEM PROVIDES AN ENDLESS RESOURCE AT ANY SPEED.

SOLUTION

GAS-STATIC BEARING

GAS-DYNAMIC BEARING

CAPACITY DEPENDS ON THE FLOW RATE OF GAS

ACS PROVIDES RESISTANCE TO STRESS

THE HIGH STIFFNESS OF THE LUBRICATING LAYER

ABSOLUTE FIRE SAFETY

LOW BEARING

CAPACITY

FIRE RISK

LOW STRESS RESISTANCE

Has successfully completed a number of large-scale technology projects for industrial plants, author of 47 scientific publications, many of them on the project subject.

HISTORY OF COLLECTIVETHE MAIN COLLECTIVE EXPERIENCE IS THE DEVELOPMENT OF UNITS OF GAS

TURBINE ENGINES FOR DIFFERENT PURPOSES, AS WELL AS AUTOMATIC CONTROL SYSTEMS BASED ON THE ELEMENTS OF JET AND HYDRAULIC AUTOMATION. ON ACCOUNT OF PROFESSIONAL STAFF - DOZENS OF PRODUCTION SYSTEMS USING PNEUMATIC SPRAY UNITS, BEARINGS AND FRICTION BEARINGS. THESE SYSTEMS HAVE TENS OF MILLIONS OF HOURS OF OPERATION.

OIL-FREE TRANSMISSION

PRODUCT TECHNOLOGY

THE PRINCIPLE OF GAS-STATIC BEARINGS – PRESSURIZED GAS IS SUPPLIED THROUGH A SPECIALLY PROFILED HOLES IN PADS, THEREBY CREATING A LUBRICATING LAYER, WHEREIN THE SHAFT ROTATES. JET CONTROL SYSTEM SUPPRESSES THE EXTERNAL LOADS AND VIBRATIONS.
