Prediction of flight performance has been dependent upon sea-level data that must be extrapolated to flight configuration; errors up to 4% in predicted specific impulse resulted because of inability to identify factors affecting extrapolation; technique permits estimation of specific impulse within 2% for conventional propellant systems at any exit area ratio with no test data; if sea-level test data are available, altitude performance can be estimated within 1%; effects of mixture ratio-distribution and interactions between injector chamber performance and nozzle are responsible for most of errors using characteristic velocity-thrust coefficient method.
