20.500.12556/RUL-104431 Zaznavanje delovanja motorja pri jadralnih letalih Detection of engine operation in sailplanes Zaključna naloga se poglablja v problematiko zaznavanja pogonskih sredstev pri jadralnih letalih. Namen naloge je akustična analiza hrupa v kabini jadralnega letala v pogojih z motorjem ter brez njega in razvoj programa, ki je sposoben ločiti med tema dvema načinoma leta. Praktični del zajema snemanje hrupa znotraj kabine v jadralnem letalu v pogojih letenja z in brez motorja pri različnih pogojih. Ti pogoji zajemajo let pri različnih hitrostih, koordinirani in nekoordinirani let, let z odprtim in zaprtim oknom, uvlečenim in izvlečenim podvozjem ter pri različnih obratih motorja. V obsegu praktičnega dela zaključne naloge je tudi hrup motorja na tleh, brez aerodinamičnega hrupa zaradi letenja. Razvojni del sloni na akustični analizi, izračunu psihoakustičnih značilk ter klasifikaciji zvoka glede na značilke dveh načinov leta. This thesis is devoted to examining the problems of engine detection in sailplanes. The purpose of this thesis is to develop a program capable of differentiating flights and parts of flights with the use of an engine from ones without an engine based on an acoustic analysis of noise inside a sailplane cabin during flight. The practical part of this thesis covers recording of noise inside the cabin of a sailplane during flight with and without the use of an engine in different conditions. These conditions include flying at different speeds, coordinated and uncoordinated flight, flying with an open and closed window and with and without landing gear deployed, as well as flying with the engine at different RPM settings. The practical part of this thesis also includes recording of engine noise on the ground, when no flight-induced aerodynamic noise is present. The development part of this research is based on acoustic analysis, calculation of acoustic and psychoacoustic features and classification of noise based on features of two different flight regimes. psihoakustika akustika zvok hrup letala jadralna letala zaznavanje motorji knn analiza psychoacoustics acoustics sound noise airplanes sailplane detection engines knn analysis true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2018-10-06 07:45:04 2018-10-06 07:45:10 2023-11-20 12:05:11 0000-00-00 00:00:00 2018 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 209851 2746.pdf 2746.pdf 1 5D568D6248BB0F3388F4B8B00AE4558C 5994dc941137d0467e17b1385e7d377935836fa19e4f634f74d2df5040c5e976 fbd991db-a1b5-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=114954 Fakulteta za strojništvo 0 0 0
