| Summary: | The article is devoted to the problem of ensuring the operability of rotary bearings of a gas turbine
engine (GTE) with an air-fuel lubrication system. The relevance of the article is due to the unexplored
processes occurring in the supports of the rotors of a GTE, in witch the lubrication and cooling of the
bearings is carried out by an air-fuel mixture. This makes it much more difficult to select the optimal
parameters of the air-fuel mixture and the operating modes of the engine, ensuring the operability of
its rotary bearings with the least loss of fuel and air pressure behind the compressor, which can lead to
a significant deterioration of the main parameters of the GTE. The solution to this problem requires
bench tests of the air-fuel lubrication system of the GTE under different operating conditions.
The purpose of this work is to develop a schematic diagram of the unit, which allows testing the GTE
rotary bearings lubricated with an air-fuel mixture under different operating conditions (operating
modes, parameters of an air-fuel mixture).
The paper identifies the parameters that affect the operability of lubricated with air-fuel mixture
bearings, a universal scheme of unit for autonomous test of an air-fuel lubrication system GTE is
proposed. The use of the data obtained from the results of these tests in the design of a promising
gas turbine engine with an air-fuel lubrication system will be possible to select the optimal parameters
of the air-fuel mixture and the operating modes of the developed engine, which will increase its
reliability, efficiency and resource |
