Analysis of data correlation between impulse and continuous combustion heated facilities

The comparison tests of impulse and continuous combustion heated facilities were conducted. For Hydrogen-Oxygen combustion heated impulse and continuous facilities, the pressure coefficient distributions of the engine flow path were coincident but the engine thrust gain in continuous facility was 10% larger than that in the impulse facility. For Hydrogen-Oxygen combustion heated impulse facility and Alcohol-Oxygen combustion heated continuous facility, the pressure coefficient distributions of the engine flow path were coincident but the engine thrust gain in continuous facility was 5% larger than that in the impulse facility.
