I don't think that mix would work as a propellent as it just detonates.

My earlier statement: Potassium Chlorate mixed with table sugar produces an intense flash when the mixture is lit but apparently neither will ingnite seperately. If it is placed in a plastic straw, a continuous whitehot flame will shoot out like a blow torch or the shuttle's solid rocket boosters.

From Wikipedia -

Solid fuels (and really, all rocket fuels) consist of an oxidizer (substance providing oxygen) and a fuel. In the case of gunpowder, the fuel is charcoal, the catalyst is sulfur and the oxidizer is the potassium nitrate. More contemporary recipies employ such compounds as sodium or potassium chlorate and powdered aluminum. (This mixture is sometimes known as "white powder"; not only is it different in appearance than black powder, it has a considerably higher energy density.)

Maybe mixture proportions and shape-of-container determine whether you get a fast detonation or a slow burn...
