Expériences Et Analyse Du Moteur À Réaction (Le V-2).

The printed text of a conference given by Ananoff at the Palais de la Découverte on May 24, 1945, published under the L’Université de Paris heading. Printed by the Imprimerie Alençonnaise, Maison Poulet-Malassis, Alençon (Orne). It runs to 31 pages with line figures and photographs.

Ananoff opens by saying it would be presumptuous to describe every rocket experiment in the world; instead he explains what a direct-reaction motor burning liquid fuel and oxidizer is, which he sees as the future of reaction propulsion, and then analyzes the German V-2 as its most characteristic example. He contrasts it with the air-breathing turbojet and the V-1, discusses fuel delivery and the pump, tanks, mixing, injection and the combustion chamber (Tsiolkovsky’s pressure-feed proposal is mentioned as ingenious but impractical), and reproduces a cutaway of the V-2 with the legend in English. A short section on the pure-reaction Messerschmitt 163 follows.

The Conclusion looks ahead to sounding the upper atmosphere and to ultra-fast intercontinental flights, such as Paris–New York in under an hour, with V-2 type rockets carrying mail rather than explosive; and the closing sentence adds that if humankind ever dreams of the other worlds of the sky, it will be through the reaction motor and it alone.
