    Sammanfattning : Unmanned autonomous vehicles, airborne or terrestrial, can be used to solve many varying tasks in vastly different environments. This thesis describes a proposed collaboration between two types of such vehicles, namely unmanned aerial vehicles (UAVs) and unmanned ground vehicles (UGVs). LÄS MER

  7. 5. Design and manufacturing of a thrust measurement system for a micro jet engine : Enabling in-flight drag estimation for subscale aircraft testing

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Anna Martinez; [2018]
    Nyckelord :thrust measurement; drag estimation; subscale aircraft; in-flight measurements;

    Sammanfattning : Good estimation of aerodynamic coefficients is of fundamental importance in the design and development process of an aircraft. Generally, these parameters are obtained using analytical, numerical and experimental methods, which are sometimes either inaccurate or very expensive. LÄS MER
