Abstract
U ovom radu je obrađena električna mreža zrakoplova Zlin 242L te je provedeno ispitivanje mreže, odnosno električnog napona i jakosti struje izvora električne energije, tokom 5 režima leta; polijetanje, penjanje, krstarenje, spuštanje i slijetanje. Navedenih 5 režima leta mjereno je u dva moda rada, normalna eksploatacija i eksploatacija sa svim uključenim električnim potrošačima. Svi podaci korišteni tokom istraživanja su dobiveni tokom stvarne eksploatacije zrakoplova koji je u vlasništvu Hrvatskog Ratnog Zrakoplovstva. Pomoću prikupljenih podataka napravljen je dijagram opterećenja električnog izvora te je određena potrošnja pojedinih potrošača i njihov utjecaj na istrajnost akumulatora. Zatim su dobiveni podaci uspoređeni s podacima iz AFM-a. Zaključeno je da je potrošnja električne energije, neovisno o modu rada, u režimima penjanja, krstarenja te spuštanja gotovo ista, a najveća tokom polijetanja i slijetanja. Međutim, razlika u potrošnji između normalnog moda rada i maksimalnog opterećenja (simulacija leta noću u uvjetima zaleđivanja) iznosi 90,5 %. Također, određeno je opterećenje električne mreže od strane pojedinih potrošača te je pomoću toga izračunata istrajnost akumulatora u slučaju otkaza generatora koja iznosi 3,17 sati pri normalnom radu, a pri maksimalnom opterećenju 1,06 sati. Time je utvrđeno da akumulator pruža više nego dovoljno vremena pilotu kako bi osigurao sigurno slijetanje.
Abstract (english)
This paper analyzes the electrical network of the Zlin 242L aircraft and tests electrical grid, meaning its electrical current and voltage from the power source, during 5 flight regimes: takeoff, climb, cruise, descent and landing. Those 5 flight regimes were measured in 2 modes, during normal operation and with all electrical consumers turned on. All dana used during research were obtained in real flight with the aircraft owned by Croatian AirForce. Collected data was then used to make a load diagram of aircraft power source and to determine individual electrical consumer's onsumption of electrical energy and their impact on battery endurance. Results were then matched with the data found in AFM. It was conculded that the consumption of electrical energy, independent of flight mode, was nearly identical during climbing, cruising and descending, and peaked during take-off and landing. However, the difference in consumption between normal operation and maximum load (simulated flight at night in icing conditions) is 90,5 %. Also, the load on the electrical network by individual consumers was determined, and with this the endurance of the battery, in case of generator failure, was calculated to be 3,17 h during normal operations, and 1,06 h during maximum load. This determined that the battery provided more than enough time for the pilot to ensure a safe landing.
