NPO Energomash has been working on methane since 1981. Methane is a cryogenic product (evaporation occurs at 160°C) and is more easily released from fuel residues. Due to this, methane fuel is better suited to development of a reusable engine and reusable air and spacecraft.
The laser ignition device was developed by NPO Energomash specialists together with the Keldysh State Scientific Center. The essence of the new technology for launching rocket engines is the initiation of an optical-induced breakdown, forming a plasmoid inside the combustion chamber when fuel components are supplied into it.
The development of electric jet engines (EJEs) started at KBKhA in 2010. This is a new area of work for the enterprise. Designed for use within spacecrafts, they are able to solve a wide range of tasks: satellites working orbit correction and stabilization, their delivery from low to high orbits, as well as flights to deep space.
The engine was designed within the research and development project on development of oxygen-hydrogen LPREs without pre-burner, for prospective LVs upper stages, boosters, and orbital transfer vehicles.
KBKhA, on Specification from the Khrunichev State Research and Production Space Center, developed a draft design of RD0162 liquid-propellant oxygen-methane engine, which was cheaper and more economical than a kerosene engine for multiple use. It is developed for multiple use within prospective reusable space rocket system (RSRS).
