Raketenflugtechnik.

Sänger’s first book, written while he was an assistant at the Technische Versuchsanstalt of the Technische Hochschule Wien, sets out to move rocket flight from speculative fantasy onto rigorous engineering footing and remains the founding treatise of winged, rocket-powered high-speed atmospheric flight. It projects an aircraft capable of ranges to about 5,000 km, altitudes near 50 km, and speeds up to 4,000 m/sec — some twenty times the speed and five times the altitude of contemporary propeller aircraft — and anticipates uses in intercontinental transport, scientific research, and, as Sänger himself notes, as a weapon of extraordinary power, foreshadowing the antipodal bomber concept he developed with Irene Bredt during the Second World War.

Its literature review situates the work alongside Tsiolkovsky, Goddard, Hohmann, and Oberth; Hohmann’s Die Erreichbarkeit der Himmelskörper (1925) and Oberth’s Wege zur Raumschiffahrt (1929), both also published by Oldenbourg, are elsewhere in the collection. Dedicated to the author’s wife, Maria Sänger.

Two different editions in Russian (1936 and 1947) also available in this collection.
