The volumetric oxidizing potential of Dinitrogen Tetroxide (N2O4) or RFNA (Red Fuming Nitric Acid) is lower compared to LOX (Liquid Oxygen).
LOX is a highly efficient oxidizer with a high oxygen concentration, and it is commonly used in rocket propulsion systems. It has a high oxidizing potential and can readily support combustion reactions. LOX provides a high density of oxygen in a liquid form, which allows for compact storage and efficient delivery to the combustion chamber.
On the other hand, Dinitrogen Tetroxide (N2O4) and RFNA are less potent oxidizers compared to LOX. While they can still support combustion reactions, their oxidizing potentials are lower. RFNA is a highly concentrated form of nitric acid that contains nitrogen dioxide (NO2) as a major component. It is a strong oxidizer but has a lower oxidizing potential compared to LOX.
The lower oxidizing potential of N2O4 or RFNA means that a larger volume of these substances is required to achieve the same level of oxidizing power as LOX. This can affect the design and performance of propulsion systems, as larger storage volumes may be necessary for N2O4 or RFNA compared to LOX.
It's important to consider the specific application and requirements when choosing an oxidizer for a particular system. Factors such as efficiency, safety, compatibility with other propellants, and storage considerations are crucial in determining the most suitable oxidizer for a given application.
