Transport aircraft performance calculation using BADA model

Rad obrađuje temu performansi odabranog transportnog zrakoplova u standardnim atmosferskim uvjetima. Performanse zrakoplova promatraju se kroz tri režima: penjanje, krstarenje tj. horizontalni let i spuštanje. Cilj rada je proračun performansi zrakoplova A320 pomoću BADA modela te usporedba s performansama iz programa PEP (Performance Engineering Program) proizvođača u navedenim režimima leta. Analiza performansi napravljena je za dvomotorni mlazni transportni zrakoplov Airbus A320 koji se koristi na manjim i srednjim udaljenostima. Rezultati izračuna pomoću BADA modela daju rezultate s manjim odstupanjima od vrijednostima iz PEP-a. Navedene razlike pripisuju se različitim polarama otpora u PEP i BADA modelu.The paper deals with the topic of the performance of a selected transport aircraft in standard atmospheric conditions. The performance of the aircraft will be observed through three modes: ascent, cruise, ie horizontal flight, and descent. The aim of this paper is to calculate the performance of the A320 aircraft using the BADA model and to compare it with the performance from the Performance Engineering Program (PEP) of the manufacturer in the stated flight modes. Performance analysis was made for the twin-engine jet transport aircraft Airbus A320 used at short and medium distances. The calculations from the BADA model show certain deviations from the results of PEP. These differences are mostly due to different drag polar use din PEP and BADA model
