THE LAYOUT SCHEMES OF PERSPECTIVE LAUNCH-VEHICLES, EQUIPPED WITH MULTI-CHAMBER PROPULSION SYSTEMS AND COMPOSITE NOZZLE BLOCKS WITH AUTOREGULATION
Design problems of layout schemes of multi-stage launch-vehicles (LV) and aerospace systems (ASS), equipped with multi-chamber propulsion units (PU) and a composite nozzle blocks with autoregulation are considered. New design-layout schemes of LV and ASS equipped with PU with LRE, simultaneously starting to operate from the launch of the first and second stages of LV, are presented. Proposals for technological improvements of flight-technical characteristics of domestic perspective LV by improving the altitude performances of PU (increase of averaged on trajectory specific impulse) at first and second stages operation, as well as to reduce the drag of LV and ASS during the atmospheric phase of flight are developed. The results of previously conducted works in Russia and abroad on the design of layout schemes of LV with pin nozzles are presented.
Keywords: launch-vehicles, propulsion units, liquid rocket engines, nozzles with central body, layout schemes.
