THE STRUCTURE DAMPING BASED ON POLYURETHANE AND GLASS WOOL FOR THE AIRCRAFT APPLICATION

Popis výsledku v původním jazyce

This paper deals with the problematic of noise and vibration of construction materials inside fuselage of one propeller aircraft (SportStar, Evektor). The aim of this work was to analyse combination materials - PUR and glass wool on the firewall of the aircraft engine space separation of the cabin, which are used as an effective sound damping materials. The sandwiches structure is dependence on the geometry between layers of polyurethane and glass wool. These structures are excellent in the lower frequency and the analysis structure isn?t any resonance frequency. In the test method was used commercially materials a laboratory apparatus for the acoustic absorption and damping of transmission. It was found that self-exhausting type of PUR and non fire glass wool materials fulfils all requirements for this type of application.
