1. 1. 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
