Separation or breakaway of over-expanded gas from nozzle wall plays important role in estimation of thrust from rocket engine when run at altitudes considerably less than design; Rocket Dept of Bristol Siddeley Engines Ltd carried out tests on experimental combustion chambers having static pressure tappings in nozzle divergent section; it is shown that pressure at which gas separates is neither constant nor independent of nozzle length; mechanism separation; effect of separation on sea-level thrust of nozzle designed for high altitude is shown.
