Abstract : A one-dimensional equilibrium thermochemistry program, originally written for air-augmented rockets, was modified to accommodate calculations for a boron slurry fuel. The program was used for the prediction of combustion temperature, product species, and air specific impulse values as a function of total equivalence ratio. The results of the modified program are shown to be in good agreement with similar results from two other equilibrium programs. Subsequent calculations were made to obtain design parameters for an experimental facility to investigate the combustion phenomena of a boron slurry fuel. Cold flow experimental tests were conducted to evaluate potential slurry injector designs. An air atomizer injector was designed that produced good initial dispersion of the slurry fuel, at a desireable flow rate, and for an acceptable pressure drop across the injector. An approach to the design of combustor cans for burning slurry fuel is presented. (Author)
