Abstract
Ovim radom opisana je kratka povijest mlaznih motora, njihov princip rada, njihova podjela te njihovi dijelovi. Detaljno je objašnjen napredak Boeinga 787 i njegovog pogonskog motora GEnx-1B u usporedbi s njegovim prethodnicima. Objašnjen je put do veće učinkovitosti i smanjenja buke motora GEnx-1B pomoću većeg dijametra ventilatora, karbonskih lopatica te inovativnih mlaznica za gorivo. Prikazano je kako je Boeing 787 sa svojom kompozitnom strukturom napravio velike korake pri velikoj učinkovitosti i udobnosti putovanja u usporedbi sa svojim prethodnicima s električnom ventilacijom, većim pritiskom u kabini te velikim prozorima. Napravljena je i ukratko objašnjena elektro-shema za ovaj zrakoplov. Napravljeni su termodinamički proračun i proračun naprezanja lopatica turbina. Na kraju su napravljeni 3D modeli inovativne TAPS mlaznice za gorivo i sklopni nacrt motora.
Abstract (english)
This paper describes the brief history of jet engines, their operating principle, classification and its components. It elaborates on the advancements of the Boeing 787 and its propulsion engine the GEnx-1B compared to its predecessors. The path to greater efficency and reduced noise of the GEnx-1B engine is explained through its larger fan diameter, carbon blades and innovative fuel nozzle. It demonstrates how the Boeing 787, with its composite structure, has made significant strides in efficiency and travel comfort compared to its predecessor with electric ventilation, higher cabin pressure and larger windows. An electrical schematic for this aircraft is also briefly explained. Thermodynamic calculations and stress calculations of turbine blades are conducted. Finally, a 3D model of the innovative TAPS fuel nozzle and assembly drawings of the engines are created.
