The article provides a classical prime cost accounting, outlining steps for calculating the cost at production site. The calculations compare two methods of manufacturing titanium parts for the aviation industry. The first method uses the mold forming by drop forging and the second one uses a modern superplastic manufacturing technology. This comparative calculation will determine the price of production of one set of parts for the SU-30. The considered methods of manufacturing parts will show the prime cost of production and will draw conclusions on further cooperation between Irkutsk Aviation Plant and Irkutsk State Technical University in the field of titanium products mold forming for modern aircraft.
