Abstract : This invention concerns a closed vessel apparatus for rapidly determining the burning rate of uncured propellant. Apparatus includes a closed vessel enclosing a propellant in a holder. An ignition wire is mounted in the vessel for igniting the propellant. A pressure transducers is provided for detecting the pressure rise in the vessel and an electronic circuit triggers the start and stop of pressure integration. This data is fed to a data print out circuit.
