Overall view of the cutaway V-2 engine combustion chamber. Picture 2 of 4. While most rocket engine diagrams and labelling from the 1950s and 1960s settled on the use of red to indicate the flow of fuel and green to show oxidizer, this V-2 cutaway seems to use blue to indicate fuel and red for oxidizer (and combustion products). Note the blue film cooling pipe at left, feeding the four film-cooling manifolds, each indicated by a blue stub pipe perpendicular to the film cooling pipe. | ||||
