The operating model is intended for studying
the design of engine systems, learning the technique of mounting
and dismantling and practical maintenance of the tank.
The operating model design makes it possible to
study the design, principle of operation and arrangement of the
engine systems, perform all kinds of engine systems maintenance
except actual filling in the lubrication and cooling systems with
oil and lubricant, as well as to shift the air intake unit (AIU)
pipe in the upper and lower positions.
The operating model should be operated in a
closed room, the carrying structure of which can carry additional
load of not less than 3 tons due to the weight of the installed
The operating model specifications are given below:

The operating model of engine systems (Fig. 1)
comprises frame 6 simulating the rear part of the tank hull
with simulator 6 of powerpack compartment top deck mounted
thereon. Inside the frame and powerpack compartment top deck simulator the
non-working simulators of the following systems are installed:
- cooling system 4;
- pre-heater and heating system 11;
- lubrication system 8;
- air supply system 3;
- exhaust gas system 5;
- air intake unit 2;
as well as working simulator of bypass gas duct valve drive 10.
The operating model frame is mounted on pillars
To provide for equipment studying, mounting, dismantling and
maintenance, and repair, if necessary, the individual SPTA kit for
this operating model is enclosed.
