Abstract
A method is presented for the comparative optimization of solid fuel ramjet fuel candidates for the maximization of total impulse in a fixed geometry combustor with respect to the relationship between the impulse, the fuel regression rate, and the stoichiometric air to fuel ratio. The performance equations are cast in terms of the air to fuel ratio and the regression rate in non-dimensional form for the relative comparison of fuels. A method is presented for the use of thermogravimetric data as a means of obtaining relative fuel regression rates from the maximum reaction rates obtained from the differential thermal analysis curves. The approach is applied to nine polymer candidates. The results of the analyses, show that fuels with the combination of low stoichiometric AF ratios, lower regression rates, and high densities tend towards the highest values of total impulse within a given geometry. The objective of this work is to develop a method for optimizing and screening potential fuel polymers at the laboratory scale level.
