The ultimate goal of this project is to build an engine which has the modularity and smooth acceleration characteristics of gas turbine engines and the efficiency and no-stall compression characteristics of piston engines. On the overall the new rotary vane engine is to have an unparallel power and low fuel consumption that is to be guaranteed by a novel thermodynamic cycle throughout operation. While setting up new performance standards, the new engine is still to be less expensive to produce, assemble and maintain.
Simplicity, Reliability and Modularity of Turbo Components
The classical reciprocating engines have complex design and vast number of parts that are altogether subjected to both high temperature and pressures. On the opposite, turbo components such as inlet, compressor, combustor, turbine and exhaust are all performing a segment of the thermodynamic cycle and therefore there are optimized either for minimum loss, high pressure, high temperature or maximum kinetic energy conversion.
Pars Rotary Vane Engine design is conceptually simple with only six moving parts, namely two vanes (one within the compressor and one within the turbine housing), two rotors (direct coupled compressor and turbine rotors) and two timing valves. This results in a dramatic decreases in manufacturing, assembly and maintenance costs and drive up operation reliability.
Unparalleled Fuel Efficiency The fuel efficiency is guaranteed by:
The largest expansion to compression stroke ratio provided by a unique thermodynamic cycle. The novel cycle of the rotary components combines the advantages of constant volume heat addition process of Otto cycle, the constant pressure heat addition process of the Diesel cycle and the full expansion capability of the Brayton cycle which greatly improves power extraction and lowers exhaust pressure and temperature levels.
A lean and efficient combustion achieved by ample mixture and burn times.
A very efficient aerothermodynamic architecture of compressor, burner and turbine components.
Power and Torque: Pars Performance Right When You Need It The Most
Pound for pound Pars rotary vane engine delivers two power stroke for every revolutions, thus four times more than a classical piston engine. Also very high torque is generated almost independent of rotary speeds. This is a huge advantage at take off that directly allows the use of smaller and hence lighter engines for the entire flight mission. In summary Pars rotary vane engine is able to generate much more power and torque per unit of engine weight.
