  1. 1. Forced response numerical investigation of a transonic compressor rotor

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

    Author : Mariana Pires Gonçalves Toco Dias; [2023]
    Keywords : Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

    Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE

  3. 2. Development of a CFD Boundary Condition to Simulate a Perforated Surface

    University essay from Umeå universitet/Institutionen för fysik

    Author : Medet Kiflemariam; [2021]
    Keywords : Computational Fluid Dynamics; CFD; Boundary Condition; Bleed; Aerospace Engineering; Aeronautical Engineering; Physics;

    Abstract : In aircraft with jet propulsion engine intakes at supersonic speed, strong pressure waves referred to as shockwaves occur, which may interact with any present boundary layers along the intake surface. The adverse pressure gradients associated with Shock Wave-Boundary Layer Interaction (SWBLI) may cause boundary layer flow separation, which can result in disturbances of the flow that can be harmful to the device or decrease engine performance.

  4. 3. On more electric airplane: case study Stockholm-Copenhagen

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Mustafa Yildiz; [2018]
    Keywords : ;

    Abstract : In parallel to growing global population, the amount of people traveling around the worldalso increases. This pushes the industry to develop more energy efficient vehicles. Theconcept of electrification of vehicles has been adopted by the aviation industry in orderto reduce environmental impacts and lower operating costs. READ MORE

  5. 4. Integrated generator for use in aircraft engines

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fredrik Andersson; [2018]
    Keywords : Integrated generator; aircraft engine; generator; aircraft generator; Technology and Engineering;

    Abstract : In this paper the use of integrated generators for airplane engines is examined. In order to accomplish this goal a combination of MatLab with FEMM and ANSYS Maxwell is used to make incrementally more and more detailed analysis of the integrated generator concept. READ MORE

  6. 5. Passive Radar Detection of Aerial Targets

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Andreas Örstadius; Erol Ali; [2017]
    Keywords : Technology and Engineering;

    Abstract : The purpose of this thesis is to construct a passive bistatic radar system using two USRP N200 software defined radios and two ordinary TV-antennas. Several auxiliary components were used in order to align and calibrate the devices including an octoclock CDA-2990, switch and signal generator. READ MORE
