121815 - Innovative Synergies in Aircraft Propulsion: the Concept of Hybrid Power Systems With Contra-Rotating Propellers 

In an era characterized by escalating emphasis on fuel economy and the mitigation of greenhouse gas emissions within the aerospace and automotive industries, this paper presents an innovative paradigm including the hybrid propeller engine with contra-rotating propellers. This article unveils a pioneering technological achievement, exemplified by our patented invention registered under the identifier IB/2021/060538, received a gold medal at the ICAN 2022 International Invention competition in Toronto, Canada, represents a noteworthy advancement in the domain of hybrid propeller engine technology.

It is imperative to acknowledge that the concept is currently in the conceptual design phase, necessitating further refinement to attain its maximum potential. The engine, characterized as a contra-rotating propeller system, engenders an efficiency gain ranging from 6% to 16% relative to single-fuel engines, with one internal combustion engine providing half of the required power and the electric motor complementing the remaining share. This innovative system comprises two distinct configurations: a dependent propeller system with two electric motors and an independent propeller system with a solitary electric motor.

This paradigm-shifting innovation effectively changes the conventional internal combustion engine into a multi-engine anti-torque system, facilitating augmented thrust generation while simultaneously reduce fuel consumption by an impressive margin of 40% to 60% when juxtaposed with conventional engine models. Beyond its commendable fuel efficiency, the hybrid engine is characterized by a satisfactory level of reliability. This is attributable to the inclusion of two electric motors, in addition to the internal combustion engine, supporting the system with the ability to adeptly manage system failures and maintain power output even under exigent circumstances. Notably, the fundamental concept of the contra-rotating propeller system is not entirely novel. However, our innovative approach harmoniously synchronizes two electric motors, thereby contains the advantages inherent in the contra-rotating system with the reliability attributes to electric propulsion.
