Oxidizer to fuel ratio

WebSCS is also governed by the nature of fuel and the effectiveness of the fuel-to-oxidizer ratios [3, 16]. The fuel-to-oxidizer ratios are, however, computed by scheming the total oxidizing and reducing valences of the fuel and the oxidizer by a standard technique proposed by Jain et al. [98]. Nevertheless, SCS is a high-temperature process that ... WebThe weight ratio of oxidizer to fuel in the combustion chamber of a rocket engine. For example, the mixture ratio for the space shuttle's main engine is 6:1, meaning six parts of oxidizer (liquid oxygen) to one part of fuel (liquid hydrogen).In 1962, NASA's Marshall Space Flight Center developed control circuits and valves for a Saturn 1B ...
