The objective of this project was to develop a calculating technique for ensuring neces-
sary operational parameters of pneumohydraulic system of a bench complex for testing
model rocket-ramjet engines. We solved this problem by using a fire air heater simulating
the conditions on entering the afterburner. The conditions were similar to those in the
flight. We developed sets of equations and performed thermodynamic calculations of the
working body structure produced by a heating gas generator at kerosene combustion in
the air and oxygen regeneration by additional oxygen consumption directly in front of the
afterburner. We obtained the equilibrium temperature values and the values of relative
mass concentration of combustion products. The values are necessary for determining
the operational parameters of the bench equipment and analysis of the experimental data
obtained at fire bench tests.
Keywords: rocket-ramjet engine, testing, operational parameters, heated air, oxygen
concentration, thermodynamic calculation.
