Abstract

Sprężające okapotowanie silnika właściwego dla silnika odrzutowego zawiera wklęsłą sekcję pierścieniową okapotowania silnika właściwego, przedstawionego na rysunku. Sekcja wklęsła zaczyna się w obrębie przestrzeni zewnętrznego okapotowania wentylatora i rozciąga się w części końcowej okapotowania wentylatora, w kierunku do stożka ogonowego, definiując pierścieniową sekcję bocznikową, pomiędzy okapotowaniem wentylatora i okapotowaniem silnika właściwego. Wklęsła geometria okapotowania silnika właściwego ogranicza siłę naddźwiękowych fal uderzeniowych, generowanych na narożnikach okapotowań sąsiadujących z naddźwiękowym strumieniem przepływu powietrza, zwiększając ogólną sprawność silnika.
