    Sammanfattning : Wallenius Marine, KTH and SSPA are working together on a wind powered car carrier, that will ship cars over the atlatic. KTH has a small scale prototype of this vessel, and uses this prototype to test performance and new sensor systems, that can be used on the full scale vessel. LÄS MER

  3. 2. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Luis Alfonso Penela Guerrero; [2022]
    Nyckelord :Aerospace; wind tunnel testing; lightweight structures; UAV; composite materials; Flyg; vindtunneltestning; Lättkonstruktioner; UAV; kompositmaterial;

    Sammanfattning : The use of wind tunnel models for aerodynamic research is nowadays indispensable to aviation progress in the last years as aircrafts have become more complex. Wind tunnel model design and manufacturing has adopted many different processes and materials such as the use of a five-axis CNC; making this process a relatively long and expensive one. LÄS MER

  5. 4. Design and Calibration of Pneumatic Probes for Aerodynamic Testing

    Master-uppsats, KTH/Farkostteknik och Solidmekanik; KTH/Kraft- och värmeteknologi

    Författare :Angelica Lejdeby; [2021]
    Nyckelord :;

    Sammanfattning : To develop turbomachines aerodynamic testing is an important part of the process. The performance testing this thesis will focus on is pressure measurements, which often is done using pneumatic probes. The pneumatic probes used in this project were a five-hole probe, a pitot probe and two different types of Kiel probes. LÄS MER
