Experimental studies of gas generator based on hydrogen peroxide and hypergolic ethanol

The calculating procedure that ethanol (C2H6O) reacting with Hydrogen peroxide (H2O2) was deduced based on chemical theory and characters of C2H6O and H2O2. An experimental gas generator installation was established and applied to research the self-ignition behavior of ethanol while it was injected into hot oxidizing gas mixture produced by decomposing of H2O2 with high concentration. The impacts of different spray nozzle types and injecting pressures on temperature uniformity of the exhausted flow field of the gas generator were studied experimentally. Test results suggested that the autogenous combustion can be realized and the calculation method can be used to predict the performance of a gas generator adequately.
