The “Laboratoire de Recherches Balístiques et Aerodynamiques” (LRBA) is created in Vernon. One of the first works was the Parca engine.

“Eleonore missile”

-Both the four auxiliary rocket engines and the main cruise-powered engine use solid fuel and are built by LRBA.

“Vexin”

-The Vexin rocket engine, with a thrust of 33 tons, was put into service in 1964. It ran on nitric acid and turpentine essence. It was used on the Diamant A launcher.

-The Coralie engine was a “cluster” of four engines, totaling 27 tons of thrust. It used UDMH and nitrogen peroxide.

“Coralie, in Villaroche”

-In collaboration with SEP (see) the Viking 5 was developed. It was used in groups on the Ariane 1 to 4.

-They use 75% UDMH + 25% hydrazine hydrate, a mixture known as UH25. The oxidizer is nitrogen peroxide.

“Viking 5” (PiP)

-The thrust is 275 kN.

“Ariane 44L launch”

-In 1971 this laboratory was transferred to SEP, the European Propulsion Society. (see).

From Appendix 9: LRBA has started SEP and SEPR, and finally they all were absorbed by Snecma/Safran. A small list appeared on the web is reproduced below:
