The results of numerical calculations of 2-D and 3-D flows and the combustion process in versions of an advanced rotational engine are presented and analysed. Based on the idea of the ramjet internal flow engine, the project of the rotary engine that generates torque on a shaft was developed and its operation analyzed. In the considered version of the rotary ramjet engine, a set of ramjet engines move around a center axis at high angular velocity to realize the supersonic airflow in their engine inlet. The only mowing part of the engine is a fast rotating disk with obliquely located channels near the external part of the disk forming ramjet engines. The channels in disk perform the functions of compressing the air, combusting the air fuel mixture, and generating thrust with the exhaust gases. The general principle of operation and performance of the rotary engine are discussed. Through the numerical solution of the steady averaged Navier-Stokes equations with k-ɛ turbulence model and non-premixed model of combustion, the basic characteristics of the flow and engine efficiency of the presented designs were predicted. The analysis focuses on the flow, combustion, and thermal challenges. Structural considerations are outside the scope of this paper. Results of the 2-D and 3-D simulations are presented in plots of pressure, fluid velocity, temperature, fuel and oxygen distribution.
