Development of LM10-MIRA liquid oxygen – liquid natural gas expander cycle demonstrator engine

Abstract

This article contains results of joint works by Konstruktorskoe Buro Khimavtomatiki (KBKhA, Russia) and AVIO Company (Italy) on creation of the LM10-MIRA liquid-propellant rocket demonstrator engine for the third stage of the upgraded “Vega” launcher. Scientific and research activities conducted by KBKhA and AVIO in 2007–2014 in the frame of the LYRA Program, funded by the Italian Space Agency, with ELV as Prime contractor, and under dedicated ASI-Roscosmos interagencies agreement, were aimed at development and testing of a 7.5-ton thrust expander cycle demonstrator engine propelled by oxygen and liquid natural gas (LNG).

An efficient modeling framework for wall heat flux prediction in rocket combustion chambers using non adiabatic flamelets and wall-functions

“…Results obtained with the corrected near-wall turbulence modeling, on the other hand, showed a substantial improvement in terms of wall heat flux when compared with both experimental data and higher fidelity simulations results. space agencies in the development of resusable and efficient methane-fueled engines [1,2,3,4], given the attractive properties of methane as a possible cheaper and denser replacement for hydrogen in launch vehicles [5,6].…”
