Abstract

Przedmiotem zgłoszenia jest dysza wylotowa dużych prędkości, zwłaszcza wentylatora albo silnika odrzutowego o charakterystycznym kształcie przekroju poprzecznego opisana funkcją matematyczną, która określa postać obszaru wyrównanego rozkładu ciśnień wywołanych przez strumień gazów przepływających dyszą. Dysza charakteryzuje się tym, że jej przekrój poprzeczny posiada kształt opisany zależnościami (wzór A), gdzie funkcje γk,k=1,2,3,4,5,6 są postaci dla t ϵ L[0;1] (wzór B). Korzystnie na środku odcinków opisanych funkcją fr(RSH({0}))={ρ(θ)eiθ:θϵ[0;2π]}=U6k=1 γk([0;1]) dla γ2; γ4; γ6, znajdują się kierownice strug gazu skierowane ku środkowi dyszy.
