The rotary engines mainly developed for the automotive industry are currently used in unmanned aircraft, portable generators and small vessels. In the early stage of the engine development, the simulation of the performance characteristics is advisable. The 3D CFD engine simulation is highly expensive in terms of CPU time demand and requires a high level of optimization to provide adequate data. This method can be used later in the development and fine engine tuning. For the design of the prototype 1D, simulation is being used as a tool to compare various designs of the engine. While the current commercially available software (GT-suite, Ricardo Wave, etc.) is being improved marginally, the functionality of the software is being tested on the piston reciprocating engines. This paper explores the possibility of the algorithms of such a software to be used on the rotary engine thermodynamic simulation and provides an approach to design a simulation model that can be solved by the software to predict the performance characteristics of the engine prototype.
