  1. 36. Wing Design for the ECO1 Aircraft

    Master-uppsats, KTH/Flygdynamik

    Författare :Gregor McKechnie; [2015]
    Nyckelord :;

    Sammanfattning : An analysis of a new wing for the ECO1 general aviation aircraft.  A new wing for this aircraft is hoped to provide better high-lift performance and a higher maximum angle of attack. LÄS MER

  3. 37. CFD Analysis and Assessment of the Stability and Control of a Supersonic Business Jet

    Master-uppsats, KTH/Flygdynamik

    Författare :Irene Borillo Llorca; [2015]
    Nyckelord :;

    Sammanfattning : Extensive research has been done on the aerodynamics of supersonic aircrafts, especially in the military and commercial airplanes’ field. Regarding supersonic business jets (SSBJs), two major problems have been addressed in past investigations: reducing the sonic boom and decreasing the NOx emissions. LÄS MER

  4. 38. CFD ANALYSIS OF PRESSURE WAVES AND LOADS ON NON-TIGHT TRAINS PASSING TUNNELS

    Master-uppsats, KTH/Mekanik

    Författare :Giovanni Forasassi; [2015]
    Nyckelord :;

    Sammanfattning : Computing the loads for a train passing a tunnel requires to predict both the external and the internal pressure variations in time, both of which are strong and quick for a non-pressure tight train. The key achievement of this work has been the development of 3D CFD Star-CCM+ overset mesh simulations capable of simulating the single train tunnel entry and tunnel passage as well as the two trains crossing inside the tunnel.

  5. 39. Electrothermal Design and Analysis of Dielectric TE01-mode Resonator Filters

    Uppsats för yrkesexamina på avancerad nivå, KTH/Elektroteknisk teori och konstruktion

    Författare :Anders Edquist; [2015]
    Nyckelord :;

    Sammanfattning : The use of dielectric resonator filters is very common in the telecommunications industry for applications with demanding filtering requirements. For high power applications in particular, TE01-mode dielectric resonators are often used because of its low losses and excellent peak power handling capabilities. LÄS MER

  7. 40. Design of a fluid rotaryjoint prototype

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Joakim Tänndal; [2014]
    Nyckelord :Rotary union; Rotary coupling; Flow loss; FRJ; RJ; Vätskeroterskarv; Vätskeroterstycke; Svivel; Roterstycke; Tryckförlust;

    Sammanfattning : This thesis, which has been carried out at the department of research and development at Cobham Antenna Systems, comprises the development of a fluid rotary joint (FRJ) prototype and shall provide a thorough insight in relevant design aspects. Based on input parameters and objectives derived from an actual Cobham project, the possibility of manufacturing a fluid rotary joint in-house has been investigated. LÄS MER
