  1. 1. Evaluation of electric actuation for fighter aircraft

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Dennis Moliner Pettersson; Anton Nygårds; [2023]
    Nyckelord :EMA; actuator; actuation; MEA; aircraft; PMSM; SHA;

    Sammanfattning : The tendency of recent years towards electrification of aircraft components and subsys-tems has opened the door for a wider usability of electro-mechanical actuators (EMAs) inthat context. EMAs are already in use in aircraft industries but mainly in civil aviation forsecondary control systems and non-critical applications. LÄS MER

  3. 2. Flight Simulator Integration in Test Rig

    Master-uppsats, KTH/Flygdynamik

    Författare :Tilda Sikström; [2021]
    Nyckelord :Flight Simulation; JSBSim; Iron Bird; real-time; Simulink; Flygsimulering; JSBSim; Iron Bird; realtid; Simulink;

    Sammanfattning : Integrating hardware in simulations is useful in many applications, for example to investigate the performance of an aircraft with the non-ideal response of a physical system. This thesis aims to integrate a flight simulator, JSBSim, with an actuator test rig, FLUMES Iron Bird. LÄS MER

  4. 3. Fåglarna som följeslagare till människorna. : Osteologiska material av fågel från båtgravarna i Valsgärde.

    Kandidat-uppsats, Uppsala universitet/Arkeologi

    Författare :Jane Jordahl; [2018]
    Nyckelord :Burial customs; Bird bones found in graves; Late Iron age; Vendel period; Valsgärde in Uppland; Sweden.; Begravningsritualer; Fågelben i gravar; Fåglar Osteologi; Vendeltid; Valsgärde gravfält; Båtgravar.;

    Sammanfattning : This paper reviews the osteological material from birds which are found in the boat graves from Valsgärde in Sweden. Based on my own work with boat grave number 13, I have studied the avian bone material to find out what kind of bird species there are in the grave. LÄS MER

  5. 4. Mechanical conception of the ERICA (ERA Iron bird CLU hArdware simulator)

    Master-uppsats, KTH/Farkost och flyg

    Författare :Pierre-Yves Girardin; [2017]
    Nyckelord :mechanical conception; ERA; robot; gantry; gimbal;

    Sammanfattning : Sending a man in space is extremely dangerous. In order to continue the space exploration, robots have to be used. Designed properly, robots can handle any kind of operations in deep space. But in space there is no support such as an after-sale service. LÄS MER

  7. 5. Local livelihoods, conservation and mining: An uneven struggle over land access in Punta de Choros, Chile

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Paula Lenninger; [2015]
    Nyckelord :Sustainable Development; Natural Resource Management; Mining; Community Development; Local Livelihoods; Artisanal Fisheries;

    Sammanfattning : The purpose of this thesis is to explore the relation between national economic ventures, environmental security and community development. It does so through a case study of the implementation process of an iron and copper mine (La Dominga Project) in a “biodiversity hotspot” in central-northern Chile. LÄS MER
