V-2 Engine Turbopump

The Udvar-Hazy Center displays a cut-away V-2 engine turbopump (next to the cut-away V-2 engine), affording the visitor the opportunity to see inside this component.

The sign accompanying the turbopump reads


V-2 Turbopump

The V-2 engine was both the world's first large liquid-propellant rocket engine and the first large rocket engine to use a turbopump. The engine and its turbopump were developed by the German army rocket group under Wernher von Braun. The turbopump was manufactured by WUMAG, Abteilung Maschinenbau.

The turbopump drew propellants from the missile's tanks and injected them under pressure into the combustion chamber. It moved nearly 9,000 kilograms (20,000 pounds) of water alcohol and liquid oxygen during the 60-second burning time. Exhaust gases from a steam generator, which turned hydrogen peroxide into superheated steam and oxygen, drove the turbine wheels in the center of the pump. The turbine wheels in turn powered the pump impellers for the two propellants.

The Air Force Museum also has a cut-away V-2 engine turbopump and cut-away V-2 engine.

I also have a number of resources regarding the V-2 engine and the V-2 missile.
