  4. 3. Aircraft Trajectory Optimization with Tactical Constraints

    Författare :Martin Norsell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; trajectory optimization; radar cross section; stealth; radar range constraints; network centric warfare; tactical constraints; multidisciplinary optimization;

    Sammanfattning : Aircrafttrajectory optimization is traditionally used forminimizing fuel consumption or time when going from one flightstate to another. This thesis presents a possible approach toincorporate tactical constraints in aircraft trajectoryoptimization. The stealth technology of today focuses on making thetactics already in use more effective. LÄS MER
