In March 1950, a pulse jet was developed by Dr. Günther Dietrich for a flying bomb. The payload was 1000 kg, remotely guided as a ground-to-ground projectile, similar to the German V 1. The laboratories of the Special Projects Division worked with a mixture of ammonium nitrate, calcium nitrate and dinitrobenzene; It had an electric impact fuze, an omnidirectional mechanical impact fuze, and a clockwork-actuated delay fuze; The system was intercommunicated, so that one of the three fuzes always detonated. It developed 500 kg of thrust and lasted 45 s. The test bench was in charge of Rizo E. Catón.
Simultaneously, Eng. Pelkas developed a stato-jet, and Dr. Günther Dietrich, together with the designer Guido Galán, developed a pulse jet with 80 kg of thrust (the dynamic test was carried out on an INSTITEC automobile chassis). Pulse jets with 14 (valve-operated) and 16 kg (Scopette type) thrust were built and tested, the former to power helicopter rotors, and the latter to be used in the self-propulsion of gliders.
Pulse jets (unidentified: in 1988 much of the historical documentation of the FMA that was in the Statistical Section disappeared).
