Reliability is a property that refers to the specified operating conditions of the
equipment. Failure is most likely to appear in cases where the technique is used at the
limit mode of its technical characteristics. The probability of achieving such a sign of the
limit state for a given period of operation of the machine can be determined at the design stage
of a new machine by calculating all cases of machine operation at the limit mode, allowed by
the technical characteristics and implemented under the action of its nominal parameters.
Currently, there are no technical means of material support that can guarantee the
troops to provide fuel, lubricants and water in cold (below minus 45 0C) and extreme
cold (below minus 50 0C to minus 60 0C) climate. For the fuel service, the mobile
refueling facilities will have to provide the technological process of the fuel Bay in their
tanks, transportation and refueling of weapons and military equipment. For their
reliable application in the Arctic conditions, special requirements are required for their
technical parameters, ensuring the trouble-free and durable operation of technological
equipment in the form of pumps, tanks, filters and fuel distribution systems. Justification
of parameters of technical means of fuel service for the Arctic conditions will allow on
the basis of a certain base area of the quality level to determine the optimal values of
the parameters of the materials of parts used for the manufacture of Assembly units of
the technological. Arctic climatic conditions can accelerate some processes of
destruction of materials or structures of parts. This leads to the use of special methods
for calculating the strength properties of materials and structures. The models
presented in the article can be used to study the use of technical means of fuel service in
the Arctic, separately justify the array of initial data, which should take into account the
special conditions of the use of materials, parts and Assembly units of technological
equipment.
