The article considers a method for improving the cooling efficiency of a gas turbine GTE based on a numerical method for calculating the thermal fields of the gas flow, using the Fine/Turbo module of the NUMECA software complex . The proposed approach will improve the understanding of the principle of cooling turbines and directions for further improvement of engines in the training of military personnel in military educational institutions.

The paper studies the evolution of the thermal process during electrofusion welding of polyethylene pipes at low ambient temperatures. It is proposed to preheat the pipe assembly with a coupling by means of a built-in heater mounted in the body of the connecting part. To obtain a temperature distribution close to uniform in the heat-affected zone, alignment is carried out. The duration of heating and leveling are determined by calculation. It is proposed to control the cooling process using a built-in heater. The power of the embedded heater with controlled cooling is determined by the solution of the inverse problem of controlling the thermal regime of the technological process.
