Zaznavanje napake na letalskem hidravličnem kolektorju z neporušnimi preiskavami : diplomska naloga visokošolskega strokovnega študijaBizilj, GregorZ neporušnimi preiskavami odkrivamo poškodbe sestavnih komponent letala in s tem preprečujemo nepotrebno povečanje škode ali letalske nesreče. V uporabi so različne metode: vizualne preiskave, metode ... s penetranti, magnetne metode, metode z vrtinčnimi tokovi, ultrazvočne metode, radiografske metode, termografske metode, akustične metode, boreskopija. V diplomskem delu bomo, z uporabo vrtinčnih tokov, ultrazvoka in penetranta, zaznavali napake na hidravličnem kolektorju. Pri rednem pregledu letala A320 smo odkrili puščanje na hidravličnem kolektorju in ker pretesnitev ni pomagala, smo ga zaradi suma razpoke pregledali v NDT-delavnici. Z metodo vrtinčnih tokov smo našli tri ločene anomalije. Nadaljevali smo z ultrazvokom, ki je na mestu ene izmed anomalij potrdil reflektor. Geometrijsko smo določili natančno pozicijo reflektorja. Dokončno potrditev razpoke smo izvedli s penetrantom, ki je potrdil razpoko na mestu prej ugotovljenega reflektorja. Na podlagi opravljenih preiskav smo ugotovili, da se metode med seboj dopolnjujejo in da izbiramo med njimi na podlagi okoliščin, v katerih moramo opraviti preiskavo. Metoda vrtinčnih tokov je hitra in kaže anomalije na površini, težja naloga je razložiti, kaj te anomalije so. Ultrazvočna metoda je primerna za pregled materiala v globini in za oceno velikosti anomalij, reflektorjev. Problematični so razni nepredvideni odboji, ki nam lahko prikažejo navidezno poškodbo. V našem primeru smo potrdili lokacijo anomalije, reflektorja in ocenili njegovo velikost. Dokončno potrditev, da gre za razpoko, smo opravili s penetrantom.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [G.
