  1. 1. Multibody modelling of the vibrations in an aircraft engine

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Charly Mollet; [2022]
    Keywords : Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

    Abstract : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. READ MORE

  3. 2. Accuracy verification of GT-Power model and reduction of computational time

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Viktor Dahl; Maja Dyrsmeds; [2022]
    Keywords : Vehicle acoustics; GT-Power; Exhaust system; Internal combustion engine;

    Abstract : The noise produced by any new vehicles is tightly regulated by the European Union which have developed a standardised method for measuring the emitted noise of new vehicles. The method involves a vehicle driving past carefully positioned microphones at a specific range of engine speeds. READ MORE

  4. 3. Identifying risks of AdBlue spray on stainless steel surfaces

    University essay from KTH/Kemiteknik

    Author : Evelina Tvinne Flyg; [2021]
    Keywords : Urea; Stainless steel; SCR; Deposit; Corrosion; Urea; rostfritt stål; SCR; Avlagring; Korrosion;

    Abstract : Utsläppskontroll, reglerad av allt strängare lagstiftning, ställer höga krav på utvecklingen av noggranna efterbehandlingssystem för avgaser. När det gäller utsläpp från dieselmotorer utgör NOx-minskning en av de största utmaningarna. För tunga fordon tacklas denna utmaning ofta genom ett SCR-system. READ MORE

  5. 4. Analysis and optimal design of a titanium aircraft bracket using topology optimization

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Vincent Curwen; Alexander Saxin; [2021]
    Keywords : Topology optimization; TOSCA; finite element method; aircraft engine bracket; multi-objective topology optimization; additive manufacturing;

    Abstract : Sustainable engineering within product development is becoming increasingly important with the ever-growing amounts of resources used to sustain the human way of life in modern times. An effective way of helping to deal with this problem is to reduce the resources used in products and components across the world. READ MORE

  6. 5. Thrust Performance and Heat Load Modelling of Pulse Detonation Engines

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Konstantin Ragozin; [2020]
    Keywords : Pulse Detonation; PDE; Heat Modelling; Thrust Modelling;

    Abstract : Pulse Detonation Engines (PDEs) are propulsion systems that use repeated detonations to generate thrust. Currently in early stages of development, PDEs have been theorised to have advantages over current deflagration based engines. READ MORE
