Quasiturbine Rotary Engine Stator Confinement Profile Computation and Analysis

Abstract: Among the most frequent questions asked about the Quasiturbine are: Why is a central differential needed And how is the stator confinement profile calculated These are strategic elements reluctantly discussed by the inventors in the past 20 years. Many are convinced that computing the correct confinement profile of the Quasiturbine rotor is not simple task, and the purpose of this paper is to help understanding the matter and the underling characteristics. Unaware of the real difficulty, some are reporting elementary solution attempts, but missing ways to control their exactitude, they are so far neither reliable, nor precise enough. Quasiturbine confinement profile is discussed in a USA patent, and exact solutions are graphically presented as the « Saint-Hilaire skating rink profile » (named after the physicist who first made exact calculations) by analogy to well-known sport skating rink. As a first hint, notice that ellipses are not acceptable solutions, which are far from unique due to undetermined nature of the Quasiturbine rotor. Contrary to circular constraints of piston engine and conventional turbine, the asymmetrical « multi degrees of freedom » concept of the Quasiturbine offers a wide variety of underlying innovative design options, and working characteristics.
