Photo shows restored air-rudder and fin detail. The grey painted barrel-strainers are both adjusted independently to reduce slack in the drive chain and avoid introducing a deflection bias in the air rudder. The 1.9kg counterbalance weight normally located at the top of the trim fin (or air rudder) is missing in this presentation. This excellent restoration is the work of Horst Beck.

Photo shows four restored graphite jet vane support blocks and bearing housings. The round plates we can see here act as heat sinks and allow heat to radiate away from the support block and bearing to help prevent expansion due to relatively rapid and uneven temperature distribution accumulation. The graphite vanes were quite brittle and cracking caused by rapid and uneven expansion could cause the vane to disintegrate. The area around the graphite vanes was exposed to the accumulation of heat not merely as a result of duration of the motor burn time but temperature was also increased at higher rates as the jet plume expanded with the decreasing atmospheric pressure as the missile gained altitude. This excellent restoration is the work of Horst Beck. Photo copyright: The Horst Beck Collection

Turbo Pump Parts Showing Steam Rotor

Turbo Pump Parts Showing Steam Rotor

Image shows allied soldier examining remains of V2 rocket turbo-pump after impact. The soldier is holding the steam turbine rotor – the large size of this part is well shown in this photo. The still lagged steam inlet manifold can be seen in the left foreground and the LOX outlet manifold (and valve, topmost) can be seen in the lower right corner.
