Abstract

U radu je analizirana elektromreža zrakoplova Pilatus PC-9M. Mjerenje jakosti el. struje i el. napona izvora el. energije je provedeno u 5 režima leta: polijetanje, penjanje, krstareći let, spuštanje i slijetanje. Na temelju mjerenja u letu izrađen je dijagram opterećenja izvora el. energije za zrakoplov koji je korišten pri analizi elektroenergetske bilance zrakoplova za dva leta; jedan u uobičajenoj eksploataciji, a drugi sa uključenim svim el. potrošačima. Nadalje, analiziran je utjecaj pojedinih el. potrošača na autonomiju akumulatora u slučaju otkaza generatora. Dobiveni izmjereni rezultati su uspoređeni sa teorijskim izračunom prema propisanoj proceduri u slučaju otkaza generatora prema podacima iz AFM-a i AMM-a. Zaključeno je da je razlika u el. potrošnji u različitim režimima relativno mala, a najveća el. potrošnja je u režimu slijetanja. Nadalje, pri maksimalnom opterećenju (let noću u uvjetima zaleđivanja), el. potrošnja je veća za 44,8 % nego u normalnom letu danju. Osim toga, dokazano je da autonomija zrakoplovne elektromreže u slučaju otkaza generatora dopušta pilotu dovoljno vremena za sigurno prizemljenje zrakoplova i u najgorim uvjetima, kada je opterećenje izvora el. energije maksimalno.

Abstract (english)

The electrical network of the Pilatus PC-9M aircraft is analyzed in this paper. Measurements of electrical current and voltage from the power source were carried out in 5 flight modes: takeoff, climb, cruising, descent, and landing. Based on in-flight measurements, a load diagram of the aircraft power source was created and used in the analysis of the aircraft's electrical balance for two flights; one in normal operation and the other with all electrical consumers switched on. Furthermore, the impact of individual electrical consumers on battery autonomy in case of generator failure was analyzed. The obtained measured results were compared with theoretical calculations according to the prescribed procedure in case of generator failure based on data from the AFM and AMM. It was concluded that the difference in electrical consumption in different modes is relatively small, with the highest electrical consumption being during landing. Furthermore, at maximum load (night flying in icing conditions), electrical consumption is 44,8% higher than during normal daytime flying. Additionally, it has been proven that the autonomy of the aircraft electrical network in case of generator failure allows the pilot enough time for a safe landing, even in the worst conditions when the load on the power source is at its maximum.
