A dual energy radiography method using basis decomposition was developed, the process
to do it is shown and it is compared against an alternate more direct method of analyzing the
data using the logarithm of the original data, concluding that this second method does work
but it is not better than basis decomposition.
This paper documents a numerical model, developed for the McGill Rocket Team based on classical chemical thermodynamics coupled with the Trebble-Bishnoi equation of state, to solve for the oxidizer tank conditions (pressure, temperature, mole flowrate and liquid/vapour equilibrium) during the operation of a hybrid rocket. This model is modular and can be coupled to fluid mechanics and combustion chamber models for a more detailed analysis of a hybrid rocket engine.
