  1. 1. Dimensioning Tools of MEA Actuator Systems, Including Modeling, Analysis and Technology Comparison

    Författare :Mohsen Torabzadeh-Tari; Göran Engdahl; Hans Bernhoff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dimensioning tools; MEA; More Electric Aircraft; EMA; Electro Mechanical Actuator; EM; Electrical Machine; Converter; Inverter; Finite Element Method; FEM; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : Aircraft design is an example of complex engineering where dimensioning tools can be valuable for the designers and decision makers in the early stage of the development process. These tools can be in form of a database over key numbers for different components or technologies. One of the critical parts of an aircraft is the actuator system. LÄS MER
