Russia's 2006-2015 Federal Space
Program envisages the development of a reusable space rocket system capable
of putting 25-35-ton payloads into low earth orbits. Vladimir Degtyar, head
of Makeev State Rocket Center (GRTs), told that in 2006 the enterprise, together
with engine, control system and launching equipment developers (KBKhA Design
Bureau for Chemical Automation, KBKhM Design Bureau of Chemical Machine-Building,
Research Institute of Machine-Building, NPO of Automatic Equipment), developed
a preliminary study report on the Rossiyanka
two-stage rocket with a reusable first stage.
A key feature of the developed concept is forming a ballistic trajectory of
the first stage's return to the cosmodrome and its soft landing using operational
engines.
A non-running landing on a small area located at a safe distance from the launch
point is used, with no binding to airfields.
Makeev GRTs proposed to develop a family of rockets based on a single gas-generator
Kerosene/LOX engine and a 10-ton LH2/LOX engine for upper stages.
The control systems for the first and second stages are based on the Soyuz-2
control system. An operational flight program will be accomplished if one of
the first stage sustainer or steering engines falls during any phase of flight.
The study project will be considered in the late 2008 and a future space rocket
intended for launches from the Vostochny Cosmodrome will be selected. The development
of a new rocket System will require 7 to 8 years.
