2023 Summer Semester Flying Robot Project Team C Article 5June 21, 2023


We have completed the process of creating a 3D CAD model of the wing and converting it into a format that can be read by the laser cutter, which we had been working on for some time. Based on the data, the laser cutter was used to cut out the main wing components such as the girders and structural members, and the assembly of the main wing framework began.
The photo shows them checking the assembly plan in front of the parts. The airplane to be built by our group will have inverted gull wings and elliptical wingtips to reduce drag and for other reasons. This makes the assembly of the girders and structural materials more complicated. In this project, we were able to complete the construction of the wingtip of the left main wing after confirming where each component should be placed.
We also discussed the structure of the joint between the wing and fuselage and the structure of the payload drop mechanism attached to the fuselage. We discussed what kind of structure would be best to reduce weight as much as possible while ensuring strength. In particular, for the payload attachment part, we are interested in creating a structure that can accommodate various sizes of payloads, and we are repeating trial and error regarding the method of dropping and the materials to be used.
From the next time onward, we plan to complete the framework for the rest of the main wing and then put up a curtain on the surface, as well as work in parallel to consider the installation position of the motor and wiring.
