This cutaway shows the internal tubing and divisions of the K-1 combustion chamber for the 109-507 Walter hydrogen-peroxide engine, which boosted the Henschel Hs 293 air-to-surface anti-shipping missile. The tubing and divisions promoted mixing of the highly concentrated hydrogen peroxide (codenamed "T-Stoff") with the permanganate catalyst ("Z-Stoff"), leading to the breakdown of the peroxide and the expulsion of superheated steam and oxygen from the engine nozzle to create thrust.
This chamber came to the National Air and Space Museum in December 1975 along with a number of other rocket artifacts developed or tested after World War II by Reactions Motors, Inc.
