Walter HWK 109-507
The Walter HWK 109-507 liquid rocket motor was specially designed to drive glide bombs such as B. the Henschel Hs 293 developed.
The engine was constructed as an independent unit together with the combustion chamber, the fuel tanks and the pressure tank for fuel delivery. The nozzle was directed downwards so that the vector of the thrust jet passed through the center of gravity of the aircraft, which resulted in a stable flight attitude.
T-Stoff hydrogen peroxide (historically: hydrogen peroxide) and Z-Stoff (aqueous solution of sodium or potassium permanganate) were used as fuel . When the two components were mixed, a chemical reaction took place, but no combustion, also known as "cold operation". The thrust of 590 kp (5.78 kN) was maintained for 10 seconds.
