Combustion behavior of liquid eutectic KNO3-NaNO3-Mannitol propellant

Experiment setup:

The propellant was heated up to 170°C till it was completely liquified, then ignited with a sparkler. It showed that one spark was enough to ignite the propellant. The propellant deflagrated in a split of a second.

The high burn rate of the liquid propellant and the low viscosity makes a liquid eutectic oxidizer/sugar alcohol based rocket engine feasible. In its simplest form the rocket engine could look like following sketch:
