Recent research has demonstrated significant advances in plasma-propelled drone technology by optimizing electroaerodynamic (EAD) thruster design. This study builds on MIT's 2018 breakthrough of the first plasma-propelled aircraft by focusing on improving thrust performance through geometric parameter optimization.
Using a combination of Latin hypercube sampling, neural network modeling, and genetic algorithms, researchers achieved substantial improvements in key performance metrics: 225% increase in thrust, 357% increase in thrust density, and 195% increase in thrust-to-power ratio. The optimized design implemented a staggered electrode configuration that reduced drag and improved aerodynamic effects.
The technology offers several advantages over conventional propulsion systems, including no moving parts, silent operation, and superior thrust-to-power ratios. However, current limitations in thrust density restrict applications to small UAVs. While this research represents meaningful progress in plasma propulsion development, further optimization is needed before widespread adoption becomes feasible.
