Electric solid propellants are being explored for use in dual-mode rocket engines because they aren’t susceptible to ignite from a spark or flame and can be turned on and off electrically. Researchers from the University of Illinois at Urbana-Champaign, Missouri University of Science and Technology, and NASA conducted experiments to understand the behavior of a high-performance electric propellant compared with a traditional propellant.“Electric solid propellants have been studied as chemical rocket propellants, but what we focused on is studying these types of propellants for electric propulsion systems—so, not the fire, smoke, and combustion you see in chemical rocket engines but for in-space electric pulsed plasma thrusters,” said Joshua Rovey, associate professor in the Department of Aerospace Engineering in The Grainger College of Engineering at the U of I.Rovey explained that in electric engines, there is a high-temperature plasma right next to the surface of the electric solid propellant. A small amount of that surface vaporizes and gets expelled out at high speeds. That’s called ablation.“Learning about the amount of ablation can allow us to better assess how it might perform as a propellant in an electric rocket engine, and better assess its lifetime,” Rovey said.Rovey said the application for dual-mode ...
