  1. 1. Attenuation of fan noise with passive methods : An experimental study in the implementation of a ducted fan inside the body of a blended wing body UAV

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Mustafa Kulbay; [2021]
    Keywords : ;

    Abstract : This report is about a novel approach to attenuation of fan noise in aerial vehicles, by way of implementing a ducted fan in the chassis of a four meter blended wing body plane. Three different one meter PVC pipes were used and their performances as silencers were tested by measuring the sound power level and calculating the insulation loss compared to a fan by itself.

  2. 2. Balancing between environmental impact and vibroacoustic performance for lightweight buildings

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Philip Carlsson; [2021]
    Keywords : Technology and Engineering;

    Abstract : Multi-storey buildings constructed in timber have become more common in recent years. A reason for this lies in the growing interest for sustainable building, where timber is seen as a particularly interesting alternative. READ MORE

  3. 3. Acoustic performance of timber volume elements

    University essay from Lunds universitet/Teknisk akustik

    Author : Oliver Olsson; [2020]
    Keywords : Impact sound insulation; Air-borne sound insulation; Cross laminated timber; CLT; Timber Volume Element; Vibration Insulation.; Technology and Engineering;

    Abstract : The thesis investigates the acoustic performance of light weight timber constructions known as timber volume elements and vibration insulation methods employed in these. Common materials used in light weight timber floor constructions and different floor configurations consisting of these materials were also studied. READ MORE

  4. 4. Game engine based auralization of airborne sound insulation

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jimmy Forsman; [2018]
    Keywords : Auralization; Building acoustics; Airborne sound insulation; EN 12354-1; Room acoustics; Audio engines for virtual reality; Game engine;

    Abstract : Describing planned acoustic design by single number ratings yields a weak link to the subjective event, especially when the single number ratings are interpreted by others than experienced acousticians. When developing infrastructure, tools for decision making needs to address visual and aural perception. READ MORE

  5. 5. Detection of stator interturn fault of synchronous machine by rotor current analysis : A SIMULATION APPROACH

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Ata-E Rabbi; [2016]
    Keywords : Synchronous machine; interturn fault; stator fault; rotor current; harmonic current; generator protection; motor protection; inductance matrix.; synkronmaskin; varvfel; statorström; rotorström; strömöverton;

    Abstract : One of the major electrical faults of synchronous machines is an interturn short circuit in the stator winding, due to winding insulation failure. A synchronous machine is designed to have electrical and mechanical symmetry in the stator and rotor. READ MORE
