  1. 1. Evaluation of electric actuation for fighter aircraft

    University essay from Linköpings universitet/Fluida och mekatroniska system

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

    Abstract : 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. READ MORE

  3. 2. Analytical tool for electromechanical actuators for primary and secondary flight control systems : Optimization of the initial design of the EMA using parametric sizing models

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

    Author : Albin Linderstam; [2019]
    Keywords : EMA; electromechanical actuators; three-phase synchronous permanent magnet motor; power-offbrake; two-stage planetary gear; ball screw; Saab Avionics Systems;

    Abstract : The number of flights have increased by 80% between 1990 and 2014, and the demand for air travel continues to increase. Even though the aviation sector contributes to economical and social benefits, it still affects the climate change [1]. READ MORE

  4. 3. Casting defects mechanical impact on turbine blades fatigue life - Engine feedback analysis

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Romain Noselli; [2017]
    Keywords : ;

    Abstract : Aircraft engines are complex, value-added high-tech systems, which possess very restrictive technical specifications. This is especially the case for turbine parts which are submitted to very hostilethermo-mechanical environments. The technical properties, such as fatigue life and creep tolerance of these parts are therefore of primary concern. READ MORE

  5. 4. Investigation and Simulation of the Heating Effects in Sandwich Cores During Vibrational Loading

    University essay from KTH/Lättkonstruktioner

    Author : Jacob Langer; [2013]
    Keywords : ;

    Abstract : GKN Aerospace Engine Systems specializes in large load carrying static structuresfor aero engines and is, as part of a light weight strategy, developing design andmanufacturing technology to be able to complement the current metallic product offerwith composite fan guide vane structures. Fan vanes in modern engines are structuraland to meet the requirements for low weight in the aircraft industry, it is necessary todesign the vane as a sandwich structure. READ MORE

  6. 5. Drilling with force feedback

    University essay from Reglerteknik

    Author : Robert Isaksson; [2009]
    Keywords : Industrial robot; drilling; force feedback; aircraft industy; impedance control;

    Abstract : Industrial robots have been used for a long time in the industry. Despite this thedevelopment of advanced force control system using industrial robots is relativelylimited. Using force controlled robot systems expands the possibility of what canbe done with industrial robots. READ MORE
