Flown V2 thrust chamber relic from February 1945. Badly damaged from impact, this head shows 4 intact LOX input pipe connections as well as exposed fuel injector inserts positioned in the inner wall of the injector pots. The inner and outer walls of the head are also conveniently exposed on this exhibit. Photo www.v2rockethistory.com

Hydraulic gear pump with close up detail showing ceramic heater element insulators with flat, possibly nichome, metal strip element threaded through them. This oil heating system was designed to maintain a specific viscosity of the oil regardless of environmental temperature, to better maintain oil flow rates and thus pump efficiency. The heating system is found only rarely on surviving relics.

This collection of parts were all found in vicinity of the Nordhausen manufacturing facility. parts include servo crankcase caps -top left, electro-magnetic switch installation plate – middle top, crank bearing covers – top right, gear pump blocks with base – centre, and crank-shaft, piston rod, and hydraulic piston – btm left. The deep recess on the piston circumference is for a rubber seal and is an interesting variation in ring seal design (at least 4 variations of piston design were employed, with three designs flown on combat missiles). A valve tilt seat is visible a little to the right of the piston. A broken servo mount stabiliser is shown – middle right. The cast piston rod, top right, has not been drilled and milled – the part is ‘raw’ as supplied by the manufacturer before machining has been completed. Normally the manufacturer’s details are machined off the metalwork – but not in this rare case. The three letter code gfa is clearly visible on the part and stands for the firm of Otto Fuchs Metallwerke.

Gear pump showing flow adjusters (two slot head screws nearest bottom of picture) and ceramic heater elements situated at each end of the block. The square drive shaft coupler (corroded but still identifiable) has been highlighted in red paint. The open holes either side are the main control valve guides. The copper spring strips visible on each oil flow adjuster provide locking and tactile feed-back for the adjusting process. This relic was recovered from Usedom island.
