The Section "Objects of Rocket Complex Ground Facilities" discussion was held at the Bauman Moscow State Technical University on February 1, 2002.

The main participators were representatives from industry, scientific and research institutes and technical Universities from Moscow, St.-Petersburg, Omsk, Kovrov and Korolev. Among them were leading designers of factories specializing in ground facilities for rocket technology, the scientists from Baltic State Technical University (St.-Petersburg), Omsk State Technical University, and Rocket Strategic Weapons Military Academy n.a. Peter The Great (Moscow) as well as the students, post-graduates and professors of Bauman Moscow State Technical University.

All presented reports were devoted to solving the pressing problems on modern development of Objects of Rocket Complex Ground Facilities, which proves their actuality.

Total of 25 presented reports on different problems on ground facilities and space launch complexes can be divided by the following directions:

Development and application of computer-based and resource saving technologies in launch complex design; design of methods of modeling and optimal control of launch complex servicing with expired guaranteed service time and space programs finance shortages; research of gas dynamics, acoustics, dynamics and heat processes characteristics in launch facilities during preparation and launch of space systems.

In direction "Development and Application of Computer-based and Resource Saving Technologies in launch complex design" the considerable interest was attracted to the reports by G.P.Biryukov "Review of modern computer-aided technologies in launch complex design" and by D.K.Dragun, V.I.Nefedov "Mathematical modeling in resource-saving design of launch complexes for light-class rockets".

The report by General Director and General Designer of Design Bureau of Transport Machinery (KBTM, Moscow) G.P.Biryukov states that the most urgent problem in space launch complex development is automation of ground preparation and launch procedures, because automation plays a vital role in providing safety of personnel by eliminating irreversible processes and necessity of human intervention during preparation procedures. The author explained the stages of solving of this problem in design of launch procedures for launch complexes "Kosmos", "Tsiklon", "Zenit" and "Sea Launch" created by KBTM.

The report made by General Director and General Designer of Design Bureau "Vympel" (Moscow) D.K.Dragun demonstrated that in financial shortages conditions the reduction of launch complex development costs becomes the main criterion for design. Author explained the application of computer-based resource-saving technologies for research on stress conditions, launch safety and practical tasks of multipurpose launch complex design. These computer-based technologies were developed for solving of special problems of launch complexes in close contact with "Launch Rocket Complexes" Chair of MSTU n.a. Bauman.

In direction "Design of methods of modeling and optimal control of launch complex servicing with expired guaranteed service time and space programs finance shortages" the most practical value belongs to the results of work, presented in reports by M.I.Stepanov "Problems of design and application of rocket fuelling systems", S.V.Kobyzev "Methods of design of centrifugal devices for gas separation from rocket fuels", V.V.Shalay "Design and research of thermal and thermocatalytic means of incinerating of toxic slimes, gas discharges and liquid industrial wastes for neutralization systems of rocket complexes".

Report of General Director and General Designer of Design Bureau of Transport-Chemical Machinery (KBTHM, Moscow) M.I.Stepanov considers design and servicing features of fuelling systems for space vehicles and apogee motors by storable propellant components and problems of extending of service life of facilities with expired guaranteed service time basing on statistics on service and failures, providing of additional tests of components, generalization of service-time data and providing guides on extending of service life.

Report of S.V.Kobyzev (MHTS n.a. Bauman) was devoted to theoretical and experimental research data on centrifugal gas separators applicable for rocket fuel gas separation resulting in significant reduction of time for this operation.

Report of V.V.Shalay (OmGTU) concerns results of research of device for catalytic incinerating of liquid and gas wastes of hazardous fuel components. Author demonstrates the possibility of significant improvement of neutralization process in a fluid-bed furnaces with catalytically active disperse material. This method allows for carrying process of insinerating at low temperatures (100…500°C), excluding the possibility of formation of vapors of heavy metals and secondary toxic gas wastes.

In direction "Research of gas dynamics, acoustics, dynamics and heat processes characteristics in launch facilities during preparation and launch of space systems" the most interest was attracted by reports of V.P.Zuzlikov, B.E.Sinilshikov, V.B.Sinilshikov, M.V.Rakitskaya "Research of water-drop screen influence on acoustic fields during launch of space rockets", V.S.Abakumov, V.V.Lomakin, N.V.Lukevich "Modeling and analysis of dynamic conditions for space vehicles launched from transport-launch containers".

Report of V.B.Sinilshikov (BGTU St-Petersburg) considers results of research on interaction of water-drop screen with acoustic fields, emerging during rocket launch. Producing of water-drop screen allows by several times reduction (on some frequencies – by tens of times) of acoustics impact on payload compartment. Reduction of acoustic impact results from acoustics energy losses on water drops acceleration and from deviation of radiation through reduction of propagation speed and shielding of acoustic waves in screen.

Report by V.V.Lomakin discusses the results of modeling and analysis of dynamic conditions for space vehicles launched from transport-launch containers, obtained while assessing of ground-based and air-based launch complex alternatives. Author took into consideration the main features of container-based launch namely non-linear interaction, one-direction contact between rocket supports and container with lateral forces, influence of gas pressure and temperature onto the rocket and container structures that allowed conducting a number of practical estimations.

Specifically mentioned should be the report presented by V.A.Khotulev "Realization and development of S.P.Korolev ideas while designing gas-withdrawing systems of space launching complexes", which most strikingly depicts the role of founders of our country's astronautics, academicians S.P.Korolev, V.N.Chelomey and V.P.Barmin while creating the most complex launch systems, being used for our country's and international projects in space exploration.
