Preliminary Analysis of the Performance of an Electric Supersonic Propeller

A preliminary aerodynamic and thermodynamic analysis of a supersonic propeller driven by an electric motor is performed. The aimed at determining whether such system feasible further more detailed investigation warranted. Recent progress in energy storage motors, as well high temperature lightweight materials, has opened up the design space for large number applications. Electrically powered flight propellers are among these This study shows that very good propulsive efficiencies can be achieved with this combination. In paper, blades explored effect parameters on blade efficiency shown. Further performed to demonstrate reasonable Mach numbers from two six between 15 35 km altitude. Finally, mission-based practical performance show trade-offs different parameters.
