Combustion Chamber, Rocket, Liquid Fuel, Robert H. Goddard, 1929

Cylindrical combustion chamber on top, tapering down to narrower diameter and adjoining long conical exhaust nozzle at bottom. With twisted propellant pipes on top of chamber. Ordinary funnel also on top. Mounting brackets at bottom of nozzle. Overall, copper chamber on aluminum display frame. The rocket itself, not seen here, was of steel alloy with aluminum vanes. To cut down the weight, the rocket was not covered and was an open framework with the components, including the exposed chamber.
