In the project "Crown" is proposed to abandon the gradual transition to reusable means of breeding. According to Molchanov, instead, the designers intend to develop a single-stage, fully reusable carrier, without intermediate stages, which only lengthen the transition time to reusable systems and make them more expensive.
The Crown will be a reusable, single-stage, vertical take-off and landing design, equipped with take-off and shock absorbers. The most energy-intensive elements in the rocket systems can be used at least 25 times, and the total resource of the rocket will be at least one hundred flights.- declared Molchanov
A specific feature of the Korona rocket will be the possibility of using a whole range of multi-launch launch systems, in which landing fuel is spent on launching a satellite and returning fuel is delivered by a carrier tanker.
The engine is considered to be an external expansion power unit with a modular combustion chamber operating on environmentally friendly fuel, kerosene and liquefied oxygen.
The main structural material is carbon fiber, ceramic tiles are used in thermal protection, RIA reports News
