Abstract

Udostępniony jest otwarty system wytwarzania ciągu, który może zawierać element obrotowy (20), mający oś obrotu wokół centralnej osi wzdłużnej i zawierający wiele łopatek (21) przymocowanych do kołpaka; element stacjonarny, usytuowany za elementem obrotowym; i wlot usytuowany między elementem obrotowym i elementem stacjonarnym w taki sposób, że wlot przechodzi promieniowo do wewnątrz względem elementu stacjonarnego. Element obrotowy wyznacza pierścieniową dolinę usytuowaną między pierwszą pierścieniową koroną i drugą pierścieniową koroną, a wlot wyznacza obszar otwarty, usytuowany za drugą pierścieniową koroną.
