1. Identification and modelling of noise sources on a realisticnose landing gear using phased array methods applied tocomputational data
University essay from KTH/MWL Marcus Wallenberg LaboratorietAbstract : Due to the recent development of quieter turbofan engines, airframe noise has started to emerge asthe most important noise source. This is particularly true during the approach/landing phase, whenthe engines are operated at low-thrust levels. READ MORE

2. Addressing Adaptive Structure Technology to Reduce the Airframe Noise(Link)
University essay from KTH/Hållfasthetslära (Avd.)Abstract : ABSTRACTThe purpose of this thesis is to design and analyze the new generation leading edge slat of a commercial jet to reduce the structural noise with the application of new conceptual design approaches. Recent scientific research show that the leading edge slats account for the structural noise during the flight operation therefore, when the leading edge slat is deployed under different flight conditions, an open gap/slot is formed between the high lift device and the wing box.
