Abstract

Cilj ovog rada je prikazati termodinamički princip rada mlaznog motora. Na početku rada napravljen je kratak osvrt na razvoja mlaznih motora kroz povijest. Prikazana je i osnovna podjela mlaznih motora te prednosti i nedostaci svake vrste. Nadalje, opisani su osnovni dijelovi mlaznog motora i njihova funkcija. U radu je opisano i prikazano jednadžbama kako nastaje potisak te je prikazan izvod do jednostavnog izraza za računanje potiska. Zatim je opisana termodinamika mlaznih motora. Prikazani su idealni i stvarni Braytonov ciklus te su navedeni gubici stvarnog ciklusa. Osim općenitog prikaza Braytonovog ciklusa, na kraju rada je prikazana termodinamička analiza turbomlaznog motora.

Abstract (english)

The purpose of this paper is to present the thermodynamic principle of a jet engine. A short history review of the jet engines is written at the beginning of the paper. The main classification of jet engines and the advantages and disadvantages of each type are also presented. Furthermore, the main parts of a jet engine and their function are described. Through equations the paper describes and presents how the thrust occurs and it shows the process to reaching a simple mathematical form for calculating thrust. Afterwards the thermodynamics of jet engines are described. The ideal and the real Brayton cycle are shown and the real cycle losses are given. In addition to the general review of the Brayton cycle, the thermodynamic analysis of the turbojet engine is presented at the end of the paper.
