Turbopump 3D CAD
3D CAD model images of the A4/V2 rocket engine’s steam turbine powered propellent pumps – all images by Ray Matter. To see Ray Matter’s blog 3D CAD modelling the V2 rocket turbopump introducing these images, just click the link.
Industrial magazine advert for Gustav Schlick printed in 1918 and showing graphic of steam boiler jets. The company, formed in 1902, had a wide expertise in all aspects of industrial spray technology and were able to steer the direction of fuel injector development along fruitful lines after they became consulting contractors to Dr Walter Thiel’s combustion research group in 1937.
Sample set of 3303D type fuel injector inserts that were found in Peenemünde in part of a group that were bunched together in a space about 300mm in diameter with the remains of packaging. They appear to be manufacturing samples and and some have been graded with numbers 1,2,3, as well as with red and white paint to show the burner cup echelon position (C or D). Five different manufacturers are represented in this group. V2RH collection image

A schematic drawing of the Askania rudder servo ‘Rudermaschine LRM 3’showing the critical compact dimentions of the device making it ideal for retro fit projects for smaller aircraft.
Trade literature advert for the Preschona company (Adolf Meyer) in Berlin, Germany. The company was a supply contractor and (among other items) manufactured the non-return valve for the steam turbine exhaust heat exchanger, employed to volatilise a small portion of liquid oxygen (LOX) to pressurise the LOX tank to maintain critical flow volume to the LOX turbo-pump.

Relic of main alcohol valve with manufacturer code aeq (aeq = Bartoc & Co., Maschinenfabrik u. Giesserei Hedwikow,bei Caslau (Caslav) Czech Republic). An air (nitrogen) inlet pressure of 440 to 530 psi (30 to 36 Bar) was required to close this valve against its internal spring and the force of the turbo-pump. The large nut at the top is the connection for the fuel return (or ‘revolving’line) pipe, and the air and electrical input ports can be seen to the right (air), and left (elec.) just below this point.

Anatomy of the V2: 18-pot injector head
Picture shows parts of V2 missile fin structure laying on open ground near area between admin offices and F1 (near Admin. block railway platform, see map).
Picture shows metal debris within the F1 factory boundary walls. The purpose of the part buried liquid storage vessel in the foreground is unknown but it is not a vessel capable of being pressurised. Other assorted metal debris include pipe and cable wall cleats, as well as steel armature rods from reinforced concrete castings (powerful demolition explosions have freed the steel rods from the concrete). These reinforcement rods are a common sight in the environs of Fertigungshalle Eins (F1) and the nearby Repair & Maintenance Hall (R&MH).
This picture shows a small debris field of steel fragments from the V2 missile 130m South-East of F1, and just 20m to the North East of the foundations of a small heat distribution building. Various body and frame parts can be seen and in the middle foreground a 350mm segment of curved missile body ring is visible. These parts have almost certainly been dug up and exposed by the action of metal detectorists. The metal fragments have been abandoned by their finders as they are perceived to have no financial value and hence are not worth removing from the site.
This picture shows a close up detail of parts in a small debris field of steel fragments from the V2 missile 130m South-East of F1, and just 20m to the North East of the foundations of a small heat distribution building. Various body and frame parts can be seen and in the upper left and two segments of curved missile body ring are visible. See previous.
This picture shows the remains of the main South entrance to the Development Works. (also known as Station 7 – Die Hauptwache).

Wooden carboy frame from WW2 (possibly used for transporting small quantities of corrosive and dangerous liquids employed in the V2 steam plant, (such as T-Stoff) laying among trees 190m East of F1 in a location used as an emergency rail freight loading area to F1 due to damage caused by US air raids in August 1944.

This picture shows Robert Dalby collecting GPS data with a mapping camera just North of the East end of the Admin office rail platform (near the ruins of the small admin/F1 heat distribution hub building). In all of our explorations we routinely collect GPS track and data points to be able to accurately locate finds and establish a precise correlation between areas of interest identified on historical reconnaissance photography and the modern ground terrain. In the picture Robert is pointing a Contour video camera at details of the terrain that automatically captures the camera’s GPS location information. This data can then be combined with satellite imagery, via Google maps, and provide a detailed graphic mapping track alongside the video footage.
This picture shows some of the extensive ruins that were once part of the railway shed complex West of the railway lines heading to the Development Works. Screen grab from Karlshagen video.

This video still shows Robert in front of a bomb crater on the West or opposite side of the rail lines and road that pass the Repair & Maintenance Hall (R&MH). The crater like so many others, created in a fraction of a second, in August 1944 during a US air raid, has developed in to a thriving eco-system that now teems with all kinds of life. After the passage of more than 70 years the crater is still deep and well defined. There are hundreds of craters like this in the area.
This video still shows the same bomb crater from a slightly different angle. The crater like so many others, created in a fraction of a second in August 1944 during a US air raid, has developed in to a thriving eco-system that now teems with all kinds of life. After the passage of more than 70 years the crater is still deep and well defined. There are hundreds of craters like this in the area.
This video screen grab shows Robert about to climb the steps up onto the rail and road loading station 9 (also called Die Verladerampen or in English, The loading ramps). This storage and loading facility was never finished during the war and was intended to be a more elaborate with large storage buildings – but the pressure of war and constant use of the area prevented further development. The area is still surprisingly intact today with a strong correspondence between modern ground detail and historical reconnaissance photography.
