A Concept for Designing a System for a Double-Launch Spacecraft System as Part of the Upper Stages of the Fregat

摘要

A concept for designing a double-launch system (SDL) for the spacecraft SDZ-La2 onboard the Fregat upper stage and the launch vehicle Soyuz-2 and SDZ-La5 onboard Fregat-SBU upper stage and the launch vehicle Soyuz-5 is presented. This concept is an innovation and differs from the existing double-launch systems. High efficiency and reliability of this SDL is verified by the works for designing SDL SYLDA-S. Some scientific results are patented.
