  1. 1. Process monitoring of turbine blades : Monitoring of blade tip clearance using eddy current sensors

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Hampus Andersson; [2022]
    Keywords : Blade tip clearance; Blade tip timing; Eddy current sensor; Turbine monitoring; Maintenance.; Bladtoppspel; Bladvibrationer; Eddy current sensorer; Turbinövervakning; Underhåll.;

    Abstract : This thesis has been a collaboration between the Royal Institute of Technology (KTH) and Siemens Energy which invest in the research facility at KTH. The objective was to investigate the use of eddy current sensors in real-time monitoring of turbine blades. READ MORE

  3. 2. Centrifugal Turbopumps - Flow Physics and Modelling

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Carl Eriksson; Hampus Henåker; [2021]
    Keywords : Centrifugal Pumps; Rocket Science; Turbopumps; Two-Zone Model; Impeller; Vaneless Diffuser; Vaned Diffuser; Technology and Engineering;

    Abstract : Choices made in the early stages of a design process are crucial. They dictate many of the limitations and freedoms the designer has in later stages of the design. Informed decisions are therefore crucial at this stage. READ MORE

  4. 3. Planetary Gear Analysis : deformation induced misalignment and optimization

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Martin Jonsson; [2020]
    Keywords : FEM; gears; KISSsoft; misalignment; planetary gears; FEM; KISSsoft; kugghjul; planetväxlar; vinkelfel;

    Abstract : A handheld heavy-duty nut runner, commonly used to assemble windmills and oil pipe lines, and capable of producing 4100 Nm of torque, experiences low cycle fatigue and usually fails after 20 000 cycles at the specified torque. A full assembly Finite element model of the last stage of the four-stage planetary gearbox is constructed and simulated over one complete load cycle. READ MORE

  5. 4. Meanline method for design and off-design turbine performance predictions

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Joel Sjödin; [2019]
    Keywords : Meanline program; space turbine; loss model; turbine predictions; early stage design; Technology and Engineering;

    Abstract : Early designs are often based on rough estimations and assumptions. Such is also the case when designing space turbines that power rocket engine fuel pumps which generally have obscure performance and size requirements. Often times, this leads to unique, single-use designs. This complicates and restricts the amount of possible testing. READ MORE

  6. 5. Modeling and Simulation of Brake Squeal in Disc Brake Assembly

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Jenny Nilman; [2018]
    Keywords : Brake Squeal; Complex Eigenvalue Analysis; Model Validation; Parametric Study; High Frequency; Brake Noise;

    Abstract : Brake squeal is an old and well-known problem in the vehicle industry and is a frequent source for customer complain. Although, brake squeal is not usually affecting the performance of the brakes, it is still important to address the problem and to predict the brakes tendency to squeal on an early stage in the design process.
