Name corresponding to "Elektro Mechanische Werke" that really hid and camouflaged the Peenemünde Army Experimentation Center, HVP.

-They made the famous V-2 (A-4) rockets that turned out to be fully operational and also their engines.

-The combustion chamber was made by Linke-Hofmann Werke.

“EMW-HVP installations”

-The intervention of Werner Von Braun (see) as director of programs, especially the A-4, was decisive. Walter Thiel intervened in the complete engine (see).

-They were assisted by others like Riedel (see).

-The engines, which is what interests us, were rocket engines with liquid fuel.

-The guided projectile (A-3), Hs117 "Schemetterling" had an EMW engine of 1,500 Kgs of thrust using B-Stoff as propellant and A-Stoff as an oxidant.

-The tanks were pressurized with nitrogen, so it did not need feeding pumps.

-Although it did have a turbo-pump for injecting into the combustion chamber.

-The A-4 (V-2 flying bomb) was the most famous one.

-The assembly line of the above picture is the one of these engines.

-It had a single chamber, a double-wall Laval nozzle through which passed fuel that cooled it until reaching the injectors on the head.

"V-2 final assembly"

-After the occupation, an American soldier observes the assembly of a V-2 (A-4) missile in its final stage.

-It looks like an underground factory.

-In the current "City of Space" Museum, in Toulouse (France) you can see the best sectioned engine of the famous V-2.

“EMW - Linke Hofmann Werke V-2”

-In the lower part, we can see the two inlets of the refrigerant fuel and above it the injector group.

-The group of injectors can be seen in detail, taken from the same exposed engine.

-The A-6, A-7, A-8. A-9 and A-10 used turbo-pumps driven by T-Stoff and Z-Stoff.

“injector bateries”

-The engine for the A-4 used B-Stoff and A-Stoff giving 27,500 Kgf. of thrust and the feeding turbines ran on T-Stoff and Z-Stoff. It was the only fully operational missile.

-The A-5 missile used engines similar to the A-3.

-The A-6 was based on the A-4 but using  "Visol" as fuel (obtained from vinyl ethers) and as oxidant SV-Stoff or "Salbei" (98% nitric acid).

-The A-8 is the A-6 using Salbei and diesel. The use of less sophisticated fuels occurred as the war became more complicated.

-The A-7 on the structure of an A-5 as tests for the intercontinental A-9 with Visol and Salbei.

-The A-10, was an intercontinental missile with the name of "Projekt Amerika" for its aims. It had two versions:

-Model I with a cluster of engines to give 165,000 Kgf of thrust with B-Stoff and SV-Stoff. (6 V-2 engines).

--Model II with six engines in  cluster using a common nozzle and giving 200,000 Kgf. of thrust with Visol and Salbei.

-The A-6, A-7, A-8. A-9 and A-10 used turbo-pumps driven by T-Stoff and Z-Stoff.

-Finally the EMW C-2 powered the "Wasserfall" with 8,000 Kgf. of thrust using Visol and SV-Stoff.

-For the "Taifun" missile with 1,000 Kgf. of thrust, the propellant was RV-Stoff with SV-Stoff or Salbei.
