Abstract

Міжлопатна площадка (3) для опорного диска (1) лопаток вентилятора турбореактивного двигуна містить центральну частину (5), жорстко з'єднану з опорним диском (1) між двома суміжними лопатками (2), і дві бічні частини (8, 9), які є продовженням двох бічних країв (6, 7) центральної частини (5) і кожна з яких виконана з можливістю прогину під дією удару лопатки (2), навпроти якої вона знаходиться.
