  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

    Sammanfattning : Hydrofoil-equipped naval vessels are not new. The technique appeared at the beginning of the 20th century and there are still new developments within the field. LÄS MER

  4. 3. Digital hydraulic actuator for flight control

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Felix Larsson; Christian Johansson; [2019]
    Nyckelord :DHA; Digital hydraulics; Flight actuation; Actuation; Digital Hydraulic Actuator;

    Sammanfattning : In aviation industry, one of the most important aspects is weight savings. This since with a lowered weight, the performance of the aircraft can be increased together with increased fuel savings and thus lowered running costs. LÄS MER

  5. 4. Digital hydraulics in aircraft control surface actuation : Modelling and evaluation of digital hydraulic systems with focus on performance and energy efficiency

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Simon Ward; [2017]
    Nyckelord :dha; digital hydraulics; hydraulics; aircraft; actuation; aircraft actuation;

    Sammanfattning : The purpose of this thesis has been to compare and analyse the use of digital hydraulic actuators in place of traditional actuators in aircraft control surface manipulation. Digital hydraulic actuator referring to a hydraulic actuator where the power has been discretized using discrete on/off-valves. LÄS MER
