A4-V2 Injection head, combustion chamber, and nozzle

The photo shows a Lichtstrahl empfänger (In English: Light-beam receiver) environmental protection case, originally one of a group of 40 or so we first found in 2010 abandon in an area adjacent to the train platform for the administration block. On subsequent visits this number has declined to just ten or so, mostly very decayed examples. The environmental casing was vital to the Lorentz Light-Beam equipment on-board the V2 missile as the critical radio frequency would otherwise drift with the large change in temperature as the missile climbed into the stratosphere. The case was thickly insulated with rock wool or fibre-glass strands and designed to help maintain a stable temperature - indeed, the same temperature as the radio equipment was when at ground level when calibration and adjustment was completed before launch. The F1 pre-production hall is located about 200m North-West of the point where this photo was taken.
