A fluid-dynamics concept that says as low-velocity gases pass into the converging part of a nozzleA type of rocket system that heats a propellantA type of rocket system that heats a propellant by passing it through a sustained electric arc, then ejects the energized gas through a nozzle. Its specific impulse is high compared to chemical rockets, but its thrust is very low. More by passing it through a sustained electricA type of rocket system that heats a propellant by passing it through a sustained electric arc, then ejects the energized gas through a nozzle.

Its specific impulseA type of rocket that creates thrust by accelerating ions in an electric or a magnetic field. Their low mass flow rate means their thrust is low, but their high-exit velocity means they are very efficient (high specific impulse). More is high compared to chemical rockets, but its thrustA type of rocket system that heats a propellant by passing it through a sustained electric arc, then ejects the energized gas through a nozzle. Its specific impulse is high compared to chemical rockets, but its thrust is very low. More is very low. […]

A type of chemical rocketA type of rocketA fluid-dynamics concept that says as low-velocity gases pass into the converging part of a nozzle, they accelerate to the speed of sound at the narrowest section (throat). Then, after they pass through the throat, they expand and accelerate to supersonic speeds. This principle is the basis for creating thrust in a thermodynamic rocket. More that relies on the energyWe use the angle of incidence, θ, to determine how much solar energy hits a solar panel. This angle lies between a line perpendicular to the cell and the Sun line. More released from the chemical bonds of the propellantA type of rocket system that heats a propellant by passing it through a sustained electric arc, then ejects the energized gas through a nozzle. Its specific impulse is high compared to chemical rockets, but its thrust is very low. More either by decomposition or combustionA type of chemical rocket that combines two liquid propellants (a fuel and an oxidizer) that burn under pressure in a combustion chamber to create a hot and pressurized exhaust that converts to thrust in the nozzle.
