| description | The study examines the fundamental technical characteristics of bladeless propulsors intended for advanced
turbofan propulsion systems in multicopter unmanned aerial vehicles. The research identifies optimal aspect
ratios that maximize thrust and thrust efficiency while analyzing the impact of fan radius and annular gap
thickness on propulsion efficiency under constant flow rate and length conditions. The findings indicate that
the most efficient configuration features a fan radius of 175 mm, a length of 150 mm, and an air mass flow
rate of 0,3 kg/s, yielding an exit Mach number of 0,42. This configuration generates a thrust of 44 N while
maintaining high-speed jet momentum conservation at 92 %, under a total inlet pressure of 17,800 Pa. |
