Oxidizer to fuel ratio
WebOct 13, 2024 · This paper evaluates various sources of oxidizer to fuel mass ratio (O/F) shifts in hybrid rockets and paths (physical phenomena) through which these O/F shifts … WebMar 15, 2014 · Assume that you are not running oxidizer rich or fuel rich. At the most basic level, you need to know the ratio of oxidizer to propellant as it appears in the combustion chemical equation. For example: 2H2 + O2 -> 2H2O This means that you need 2 MOLES of hydrogen for each MOLE of oxygen. http://en.wikipedia.org/wiki/Mole_ (unit)
