Popis: Tema ovog završnog rada je analiza performansi modernog lovačkog zrakoplova Chengdu J-20, dvomotornog jednosjeda s mogučnošću prikrivanja odraza konfiguracije kanard - delta krilo koji je prošle godine uvršten u kineske zračne snage. U svrhu te analize promatrat će se zrakoplov značajkama nalik na J-20 kojemu je dodijeljen mlazni motor modeliran prema sličnim motorima te koji po karakteristikama nalikuje motoru AL-31FM2 zrakoplova J-20. Usvojena je polazna geometrija i prikupljeni su svi potrebni podatci o zrakoplovu. Izračunat je otpor te su prikazane značajke pogona. Primjenom metode ukupne energije analizirane su performanse od interesa za lovačke zrakoplove: područje uporabe, višak specifične snage zrakoplova, brzina penjanja i koordiniranog zaokreta te su ti rezultati uspoređeni sa zrakoplovom Eurofighter Typhoon. The topic of this thesis is performance analysis of a modern fighter Chengdu J-20, a twinjet single-seat stealth aircraft with canard-delta wing configuration, which was enlisted in the Chinese Air Force last year. For the purposes of this analysis, an aircraft with features similar to the J-20, which has a jet engine assigned modeled on similar engines and which resemble the engine AL-31FM2 of the J-20 aircraft, will be observed. The starting geometry was adopted and all the necessary aircraft data was collected. The drag has been calculated and the engine characteristics are shown. With application of the total energy method the performance of interest for the fighter jets were analyzed: area of use, excess specific power of the aircraft, climb speed and the coordinated turn. These results were then compared with the Eurofighter Typhoon aircraft.
