For this rocket project we have the option to use black powder which is already made, or sugar fuel which you have to make yourself. Before choosing what kind of fuel to use we have to find out a little bit about of them, to make sure we make the best decision for our rocket motor.
Black Powder: Black powder is motor fuel that is commonly used in smaller rockets, it consists of three ingredients, Sulfur, Charcoal, and Potassium Nitrate (KNO3). Black powder usually has a fast burn rate, but if any other ingredients are added it can hinder that, and will slow it down. Also it can be used as a propellant instead of using zinc-sulfur, because it has more consistency. Sugar Rocket Fuel: Sugar fuel isn't used as often but that doesn't mean it's hard to make, there are only three ingredients needed and they each play a key role for the motor. The first ingredient is Sorbitol is the fuel which can be found in fruits because it's the sugar in them, Potassium Nitrate the oxidizer, and Red Iron Oxide is a catalyst so it increases the rate of the thrust, and enhances burn rate.
