Systems for generating thrust force outside the propeller

This article presents conclusions regarding the potential for improving the operational indicators of piston aircraft engines by using thrust generation systems outside the propeller. In this case, energy normally lost in emitted heat and exhaust kinetic energy is utilized using a proprietary flow channel design, significantly more efficient than previously used confusor based solutions. The analysis is based on ongoing design work. To further illustrate the issue, calculations for an existing aircraft engine and its impact on operational indicators are also presented. The article provides a computational procedure that serves as a basis for further research and presents favorable results.
