Cutaway section of fuel and liquid oxygen (LOX) injector pot. The exhibit shows the bell shaped thick inner wall of the burner with three tiers of fuel injector inserts (A,D, and E). As well as the two rows of plain drilled apertures B and C. The central copper alloy LOX spray injector is also well displayed in this image and shows the three letter armament code of the manufacturer (elr = H.K. Rudolf, Pilsen) and the 1943 date of manufacture on one face of the hex nut. Note the close proximity of the tier A injector inserts to the LOX injector. The spary from these injectors plays directly onto the lower section of the LOX spray head. This section of the burner cap had the lowest temperature and as a result tier A insert did nor require cooling pres. See associated picture. V2RH image
