Long description of figure 1

Many straight copper tubes are formed into a complex shape resembling the profile of an hourglass. The bent tubes are placed on a mandrel to hold them in place. They are joined together using one of several methods, such as depositing electroless nickel on the outside to form a converging-diverging nozzle combustion chamber.
