FIELD: engines and pumps.
SUBSTANCE: turbomachine high-pressure turbine stator comprises annular housing, sector webs and air circulation casing angular sectors. The latter are arranged to make continuous circular chamber surrounding turbine rotor blades. Air circulation casing angular sectors feed air onto casing to allow adjusting the gap nearby turbine rotor blade faces. Proposed method comprises setting stator elements angular distribution pattern for preset angular sector to rule out coherence of angular positions of zones arranged between adjacent webs and casing intersector zones between adjacent casings. It includes also extending the pattern above to entire circumference of stator. Other invention of the set relates to turbomachine high-pressure turbine stator assembled as specified above.
EFFECT: higher efficiency and longer life.
