METHOD OF FIRING TESTS OF LIQUID PROPELLANT ROCKET ENGINES

摘要

FIELD: routine technological tests. SUBSTANCE: according to proposed method, each engine is subjected to short-time firing tests without subsequent overhauling. Tests are carried out using gasoline as fuel, and after testing before and after demounting of engine from test stand inner spaces of engine are subjected to alternate low-vacuum evacuation and nitrogen blowing. After demounting, nitrogen blowing of engine is carried out using hot nitrogen with external heating of engine. EFFECT: reduced time and cost of cleaning of engine inner spaces from remnants of gasoline after carrying out firing routine technological tests.
