Abstract
Zakretnom cjevastom sapnicom sa pomičnom pregradom za propulziju isprekidanim visokotlačnim plinom se rješava tehnički problem brzine ostvarenja stacionarnog odnosa trenja u prednjem i zadnjem dijelu sapnice, te zaustavljanja i kretanja unazad plovila (kod primjene u vodi). Visok omjer tlaka u prednjem i zadnjem dijelu sapnice 1, postiže se ugradnjom pregrade 2 na ulaznom dijelu tijela sapnice 1. Pregrada 2 u prvom brizgaju plina zatvorenošću uzrokuje obavu ukupne ekspanzije prema izlazu sapnice. Ubrzana zadnja masa fluida nastavkom gibanja i nakon izvršene pune ekspanzije potlačnim razvlačenjem plina prenosi netom primjenu energiju za podizanje pregrade 2 i povlačenje prednje mase u pravcu izlaza. Prekid brzog protoka drugim brizgajem izaziva visoki otpor i tlak u prednjem fluidu sa vrlo malim uzmakom ekspanziji. Ponavljanjem prijenosa dodane energije na uvlačenje i ubrzanje prednje mase slijedećeg takta, uz povećani prednji otpor od rasta plovne brzine, smanjuju se ustupanje ekspanziji, koje dolaskom u stacionarno stanje i potpuno nestaje. Pregrada 2 se prislanja uz gornju stijenku sapnice 1, a potisak se u cijelosti provodi preko trenja fluida sa stijenkama sapnice 1. Zaustavljanje i vožnja unazad obavlja se zakretom sapnice 1 sa ispusnim ventilom 5 oko osi cilindra generatora plina.
