Abstract

[0003] W jednym aspekcie, rozwiązania odnoszące się do silnika turbinowego zawierającego wirnik posiadający wiele promieniowo ułożonych płatów rozłożonych na obwodzie wokół wirnika, z płatami zakończonymi końcówką, i zespołem bandaża (100) otaczającym płaty i obejmującego elementy bandaża mocowane do każdej końcówki i posiadające przeciwległe promieniowo zakończenia z pierwszymi i drugimi elementami zamków, w których pierwszy element zamka pierwszego elementu bandaża współpracuje z drugim elementem zamka obwodowe przyległym, w celu stworzenia wielu zamków pomiędzy przyległymi elementami bandaża na obwodzie płatów. [0004] W kolejnym aspekcie, rozwiązania odnoszą się do blokującego się zespołu bandaża dla silnika turbinowego zawierającego wiele promieniowo ułożonych, obwodowo rozmieszczonych płatów zakończonych elementami bandaża i posiadających przeciwległe strony promieniowe z pierwszymi i drugimi elementami zamykającymi, które zatrzaskują się tworząc zamki pomiędzy obwodowo przyległymi płatami. [0005] W jeszcze jednym aspekcie, rozwiązania odnoszą się do sposobu formowania bandaża wokół wielu obracających się łopatek w silnikach turbinowych polegającego na formowaniu zamka pomiędzy obwodowo przyległymi końcówkami łopatek i wstępnego obciążania zamków.[0003] In one aspect, solutions relating to a turbine engine comprising a rotor having a plurality of radially arranged lobes distributed circumferentially around the rotor, with lobes ending in a tip, and a bandage assembly (100) surrounding the lobes and including bandage elements attached to each end and having opposite radially ends with first and second lock elements, in which the first lock element of the first bandage element cooperates with the second adjacent lock element, to create multiple locks between adjacent bandage elements on the periphery of the panels. [0004] In a further aspect, the solutions relate to a locking bandage assembly for a turbine engine comprising a plurality of radially arranged, circumferentially spaced panels ending with bandage elements and having opposite radial sides with the first and second closing elements that latch to form locks between the peripherally adjacent panels . [0005] In yet another aspect, the solutions relate to a method of forming a bandage around a plurality of rotating blades in turbine engines consisting in forming a lock between the circumferentially adjacent blade tips and preloading the locks.
