īy the end of 1948, Aerojet had designed, built, and tested a liquid hydrogen pump (15 cm diameter). They obtained some German radial-vane pumps from the Navy and tested them during the second half of the year. īy mid-1948, Aerojet had selected centrifugal pumps for both liquid hydrogen and liquid oxygen.

Bosco subsequently used Singelmann's data in designing Aerojet's first hydrogen pump. Aerojet representatives visited Ohio State University where Florant was working on hydrogen pumps, and consulted Dietrich Singelmann, a German pump expert at Wright Field. During the second half of 1947, Bosco and his group learned about the pump work of others and made preliminary design studies. The principal engineer for turbopump development at Aerojet was George Bosco. The first successful V-2 launch was on October 3, 1942. : 172 The first engine fired successfully in September, and on August 16, 1942, a trial rocket stopped in mid-air and crashed due to a failure in the turbopump. : 80 The V-2 rocket design used hydrogen peroxide decomposed through a Walter steam generator to power the uncontrolled turbopump : 81 produced at the Heinkel plant at Jenbach, so V-2 turbopumps and combustion chamber were tested and matched to prevent the pump from overpressurizing the chamber. In mid-1935 Wernher von Braun initiated a fuel pump project at the southwest German firm Klein, Schanzlin & Becker that was experienced in building large fire-fighting pumps. High-pressure pumps for larger missiles had been discussed by rocket pioneers such as Hermann Oberth. The V-2 rocket used a circular turbopump to pressurize the propellant.
