Abstract

Nakon subjektivne procjene da je buka helikoptera prekomjerna te da utječe na
sigurnost letenja i zdravlje letačke posade, a do koje je došlo uslijed svakodnevnog
obavljanja zadaća na helikopteru tipa Mi – 8 MTV-1, pristupa se detaljnijoj obradi teme
unutarnje buke na spomenutoj letjelici u okviru diplomskoga rada. Cilj je rada ustanoviti
razmjere učinka buke temeljem provedenih mjerenja i analiza. Kao uvod u tematiku, prvi
dio rada donosi teorijske osnove neophodne za pobliže upoznavanje s temom. Drugi dio
rada opisuje specifičnosti helikoptera Mi – 8 MTV-1 – njegove karakteristike, izvore buke
kod tog tipa letjelice te mjere zaštite. Za potrebnu analizu izvršena su mjerenja unutarnje
kabinske buke na samom helikopteru u letu po unaprijed zadanim režimima. Analizom
dobivenih rezultata ustanovljeno je ima li buka doista štetan utjecaj, odnosno je li
subjektivna procjena prekomjernosti buke ispravna.

Abstract (english)

After subjective estimation of helicopter noise as being rather excessive and having an
impact on flight safety and health of the aircrew, brought in the course of daily operations
on helicopter Mi – 8 MTV-1, the topic related to the internal noise on the aforementioned
aircraft has been thoroughly developed within the MA thesis. The aim of the thesis is to
establish to what extent is the impact of noise based on the noise measurements and their
analysis. The first part of the thesis provides theoretical background necessary for the
topic introduction. The second part describes specifications of helicopter Mi – 8 MTV-1 –
its characteristics, noise sources and protection measures. The measurements of the
helicopter interior noise levels during the flight have been performed, based on criteria
previously set. The analysis of the results identified whether the noise has the negative
impact indeed, i.e. whether the subjective estimation of noise excessiveness is justified.
