im trying to cast smokeless powder into a rocket motor (bates grain geometry or maybe just single grain cored geometry). i've come up with one possible solution, and im just looking for input.

 

sugar, detergent, water, nitrocellulose powder. compact into the grain mold, and leave in a curing oven over the course of a few days at 110ish degrees. any insight or other possible solutions?

anyone at all? my thought process is that sugar should act as a binder, and as a decent fuel, it shouldn't detract too much impulse, the detergent water is the solvent, so the sugar should harden up the motor once all the detergent water is out of the mixture...and since smokeless powder is a plastic, there should be no problem with dissolving the KNO3 normally found in regular "black powder". any thoughts?
