Development of a Turbo Rotary Engine’s Combustion Chamber


Combustion chamber and turbine component of a novel turbo rotary engine has been analytically and experimentally tested. The novelty of such engine emanates from its aerodynamic rotor and housing geometries and its unique thermodynamic cycle. When compared with piston-type engines, the turbo rotary engines have advantages brought by low inertial forces and aerodynamic rotor shape that allow the engine to reach high rotational speeds. With such properties, it is thought that this engine will answer the performance range gap that lies between gas turbines and piston engines. Pars Engine is a new turbo rotary engine design with small size and low part counts and it is directly coupled efficiently to the propeller of unmanned air vehicles without the need for an intermediary gear thanks to its 5000-20000 rpm speed ranges. The same engine is also designed and tested as high efficiency generator driver to be used in hybrid vehicles and home based distributed energy generation. This study describes the development of different combustion chambers designed with computer simulations and manufactured accordingly such that all are feeding the turbine component. The effects of manufactured combustion chambers on engine’s performance are investigated. The tests are carried out for each combustion chamber design at different engine speeds and fixed turbine air input mass flow rate.
