Russian engineers from Voronezh started working on an experimental method for new engine RD-0110R, designed for carrier rocket “Soyuz 2-1V”.
      
      Engineers recently performed a successful cold start test – a so called “cold-flow test”, when an engine is tested without fuel ignition. Few more similar tests are required, before first firing trials would be performed.
      
      New liquid fuel rocket engine RD-0110R, being a part of a first stage of a rocket carrier, will enhance booster thrust and act as control engine for the initial stage of putting the carrier rocket to space.
