Abstract

Cilj ovog rada je energijska analiza teorijskog Braytonov desnokretnog procesa.U početku rada napisan je kratki osvrt na povijest mlaznih motora.Nakon povijesti su opisani glavni dijelovi mlaznih motora i karakteristične njihove podjele. U radu su opisani otvoreni i zatvoreni Braytonov proces,te su isto opisani idealni i realni Braytonov proces te su navedeni gubitci realnog ciklusa. Provedena je i matematička analiza ciklusa.Tijekom matematičke analize promatrano je potpuno izgaranje goriva i promjena sastava radne tvari kao i fizikalnih svojstava. Na temelju zadane potrebne snage plinske turbine određen je količinski i maseni protok goriva u režimu maksimalne dobivene snage. Za isti količinski protok u režimu maksimalne snage određena je neto dobivena snaga,snaga kompresora i snaga turbine za režim maksimalnog termičkog stupnja djelovanja.

Abstract (english)

The purpose of this paper is energy analysis of theoretical Brayton cycle.At beginning of paper is written short history review of the jet engines.After a history are given the main parts of jet engines and their characteristic classifications.The paper describes open and closed Brayton cycle, ideal and real Brayton cycle and described real cycle losses.Mathematical analysis of the Brayton cycle is implemented.During mathematical analysis is observed the complete combustion of fuel and changes in composition of the working substance as well as the physical properties.Based on the default required power gas turbines is determined molar and mass flow of fuel in the mode of maximumproduced power.For the same molar flow in the regime of maximum power is determined netto produced power,compressor power and power of turbine for the regime of maximal thermal efficiency.
