    Nyckelord :Electrification; Hydraulic systems; Efficiency; Electromechanical Actuators; Tiltrotator.; Elektrifiering; Hydrauliska system; Verkningsgrad; Elektromekaniska aktuatorer; Tiltrotator.;

    Sammanfattning : As new emission regulations in the EU set more stringent requirements on greenhouse gas (GHG) emissions, original equipment manufacturers (OEM) must find ways to align with the EUs sustainability goals. By transitioning to more electrically driven machinery, operators of off-highway vehicles can benefit from better fuel economy, lower greenhouse gas emissions and less air pollution. LÄS MER

    Sammanfattning : A common dilemma in aircraft design is the importance of knowing weight characteristics at early design stages, since sizing of many important components is dependent on these. Yet precise weight data cannot be determined until the aircraft and its subsystems have been designed in detail. LÄS MER

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

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

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

    Sammanfattning : 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]. LÄS MER

  5. 4. Design of Power Off Brake : Utveckling av testutrustning

    M1-uppsats, Högskolan i Jönköping/JTH, Produktutveckling

    Författare :Simon Berglund; Joel Lennartsson; [2018]
    Nyckelord :elektromagnetisk; broms; testrigg; testutrustning;

    Sammanfattning : The goal with this thesis is to find together with Saab Avionics Systems the correlation between applied current, air gap and forces that a brake with an electromagnetic release function have. This is achieved through theoretical calculations and practical tests. LÄS MER

  7. 5. Concept Development of anElectromechanical Cylinder : With a Cascade Gear Unit

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Karl Bergqvist; Linn Sevefjord; [2014]
    Nyckelord :electromechanical cylinders; concept development; cascade gearbox; elektromekanisk cylinder; konceptutveckling; kaskadväxel;

    Sammanfattning : A new invention has been developed by CorPower Ocean; a mechanical rack and pinion solution called a cascade gearbox. The primary function of the gearbox is transforming a linear motion into a rotational motion. The novelty is its unique properties; it is capable of combining heavy loads and high velocities, and at a high efficiency. LÄS MER
