Propellant Analysis Using Combustion Driven Potato Cannon
A potato cannon was designed to accommodate several different experimental propellants. Both combustion
chamber and barrel were made of polyvinyl chloride (PVC). Five experimental propellants were tested: propane (C3H8),
acetylene (C2H2), ethanol (C2H6O), methanol (CH4O), and butane (C4H10). Cylindrical projectiles were cut from raw
potatoes so that there was an airtight fit, and each weighed 50 (± 0.5) grams. This prototype of potato cannon is used for
the hydrocarbon fuel analysis means which fuel burns more drastically, which burns moderately and which burns
inefficiently means using different fuels we get different velocity of projectile as well as different recoil velocity of the
barrel and combustion chamber. In this way by performing this experiment we can have a general idea about which fuel is
good at combustion and have high calorific value.
