Abstract

Ovim radom opisuju se osnovni pricipi rada turbo-mlaznog motora i njihova podjela. Također razmatra se i potisak mlaznog motora kao glavni faktor performansi mlaznog motora gdje su formulirani matematički izrazi za potisak. Posebna pozornost posvećuje se detaljnijem opisivanju načina indikacije potiska mlaznog motora pomoću dva primarna načina indikacije potiska, N1 brzine vrtnje niskotlačnog kompresora ili brzine vrtnje ventilatora kod mlaznih motora s visokim stupnjem optočnisti i pomoću omjera ukupnih tlakova motora (EPR), ispitujući njihova načela rada, prednosti i ograničenja.

Abstract (english)

This thesis describes the basic principles of turbo-jet engine operation and their division. Jet engine thrust as a major factor in jet engine performance indication is being discussed where mathematical expressions for thrust are formulated. Particular attention is being put into describing the jet engine thrust indication methods in more detail using the two primary thrust indication methods, N1 low-pressure compressor speed or fan speed in high-bypass jet engines and using the engine pressure ratio (EPR), examining their working principles, advantages and limitations.
