Abstract : The report contains research results obtained from experimental and theoretical studies of subsonic and supersonic burning in ramjet combustors during the period 1 April 1972 to 31 March 1973. Hydrogen-oxygen mixtures sensitized by chlorine have been ignited photochemically at flow speeds from 350-550 m/s and photochemical ignition limits have been measured at pressures between 100 and 400 mmHg. The formation of weak detonation has been observed. Calculated ignition delay times have been found to agree satisfactorily with experimental values. Tables and graphs have been prepared for quick predictions of the changes resulting from heat addition to an existing sub- or supersonic flow, such as those in ramjet combustors.
