Abstract

Przedmiotem ubezpieczenia jest układ o zmiennej geometrii i działaniu rozdzielonym do sprężarki silnika turbinowego. W dokumencie ujawniono przykładowe układy o zmiennej geometrii z rozdzielonym uruchamianiem. W jednym przykładzie zapewniono sprężarkę (610), która zawiera stopień (610c) sprężarki i układ uruchamiający. Stopień (610c) sprężarki zawiera wiele łopatek nastawnych kierownicy rozmieszczonych wzdłuż, obwodu stopnia (610c) sprężarki. Układ uruchamiający służy do uruchamiania pierwszej łopatki nastawnej kierownicy stopnia sprężarki według pierwszego harmonogramu i do uruchamiania drugiej łopatki nastawnej kierownicy stopnia sprężarki według drugiego harmonogramu.
