Cost Engineering – The new paradigm for space launch vehicle design

The paper describes the basic definition and application of 'Cost Engineering' which means to design a vehicle system for minimum development cost and/or for minimum operations cost. This is important now and for the future since space transportation has become primarily a commercial business in contrast to the past where it has been mainly a subject of military power and national prestige. Several examples are presented for minimum-cost space launch vehicle configurations, such as increasing vehicle size and/or the use of less efficient rocket engines in order to reduce development and operations cost. Further a cost comparison is presented on single-stage (SSTO)-vehicles vs. two-stage launchers which shows that SSTOs have lower development and operations cost although they are larger, respectively have a higher lift-off mass than two-stage vehicles with the same performance. The design of a space tourism-dedicated launch vehicle is an extreme challenge for a cost-engineered vehicle design in order to achieve cost per seat not higher than $50,000. Finally an outlook is presented on the different options for manned Earth-to-Moon transportation modes and vehicles – another most important application of 'cost engineering', taking into account the large cost of such a future venture.

The famous son of Ukrainian people V.I. Voznyuk who has provided launch of all ballistic missiles of the cosmodrome Kapustin Yar

The history of the life of V.I. Voznyuk is a history of the phenomenon of the Soviet rocket progress when the engineers with experience of launch of military rocket of small radius of action were testing the ballistic missiles. The remarkable and little-known destiny of Voznuk is the history of the Soviet rocket technology experts who had a severe practical schooling of command by the military forces of the first combat missiles “Katucha” during the grim military years (including the grandiose fight in Stalingrad) and then they have continued to launch the ballistic missiles. V.I. Voznyuk worked as the chief of the first Soviet cosmodrome Kapustin Yar for almost 30 years—since the most difficult moment of its organization. He organized a launch of the first Soviet ballistic missiles R-1, R-2, R-5M of S. Korolev. This report is about the outstanding achievement of the organizing ability of V.I. Voznyuk—about the launch of a missile with a nuclear warhead in 1956. V.I. Voznyuk closes a unique chain in the world of outstanding figures of space-rocket technology who were born or lived in Ukraine from designers of missile up to the organizers of its manufacture and now up to the organizers of the tests of rockets—J. Aizenberg, V. Budnik, O. Baclanov, V. Dogujiev, M. Galasj, N. Gerasuta, V. Gluschko, B. Gubanov, A. Gudimenko, I. Ivanov, G. Kesunjko, B. Konoplev, S. Korolev, V. Kovtunenko, V. Kukuschkin, O. Makarov, A. Nedaivoda, M. Reshetniyov, Yu. Semenov, V. Sergeev, Yu. Smetanin, V. Tchelomey, D. Torchiy, V. Utkin and M. Yangel.
