Annotation: There has been developed a method of calculating and optimizing parameters of Stirling engines on the basis of the adiabatic model of their thermodynamic cycles. An engine generalized scheme is introduced, and the order of calculating its parameters relative to the heat exchange processes in its internal operating contour, external contours of a heater and cooler is determined. Compression and expansion processes in cylinders are considered as adiabatic. Hydraulic losses of a working body energy in the internal contour and external devices are taken into account. Energy losses at heat exchange and heat regeneration are analyzed. Energy expenses to drive auxiliary units, mechanical losses on friction are calculated. Internal and effective efficiency factors of engines are determined. The calculation results by the isothermal and adiabatic models are compared, and their comparison with the experimental data for pilot engines is done.
Keywords: Stirling engine, a thermodynamic cycle, an adiabatic model, an internal contour, heat losses, mechanical losses, an efficiency factor.
