This page presents the first hand sketches for my Fab Academy 2020 final project.
Table of Contents
1 General prototype of the sketches
The figure 1 presents the general prototype of all the hand sketches bellow.
2 Sketches of a conservation drone
This 3D overview shows all the modules put together and what the drone may look like at the end of Fab Academy 2020.
2.1 Drone design 1
The figure 2 shows a design idea for a monobody drone.
2.2 Drone design 2
The figure 3 shows a design idea for a two body drone. This design is directly inspired from the drone displayed in the front cover book [1].
Remark:
- carbon tubes will be used for the rigidity of the drone.
- Laser cut wood 2D parts, that assemble in 3D, will be used to form the skull of the module.
- Model aircraft canvas, that shrink when heated, will be used to cover each module.
Example of a commercial rc airplane built from a kit
In figure 4 one can see a kit with separate fuselage, 2 wings and a cockpit. Each is mainly made from balsa wood, covered with canvas. The carbon tube strengthen the connection between the fuselage and the wings.
3 Sketches of fuselage modules
3.1 Sketches of central fuselage module
3.1.1 Sketch of part 1 for central module
Figure 5 shows the vertical part of a central module for the fuselage of the drone.
In this part, 4 carbon tubes will pass trough the part 1, the center of the part is empty to allow space for electronic and/or payload and the blue part are laser engraved to glue bend cardboard easily on it. The cardboard will serve to support and shape the canvas covering the central module.
3.1.2 Sketch of part 2 for central module
Figure 6 shows the horizontal part of a central module for the fuselage of the drone.
3.1.3 Sketch of assembling the central module
A central module is the assemblage of 2 part 1 and 8 parts 2 as shown in figure 7
4 Sketches for the wing modules
4.1 Sketches for central wing module
4.1.1 Sketch for part 1 for central wing module
Figure 8 shows the vertical part of a central module for the wing of the drone.
In this part, 4 carbon tubes will pass trough the part 1, the center of the part is empty to allow space for electronic and/or payload and the blue part are laser engraved to glue bend cardboard easily on it. The cardboard will serve to support and shape the canvas covering the central module.
4.1.2 Sketch for part 2 for central wing module
Same sketch as in figure 6.
4.1.3 Sketch for assembling the central wing module
A central wing module is the assemblage of 2 part 1 and 8 parts 2 as shown in figure 9.
4.2 Sketch aileron wing module
Figure 10 shows an idea of an aileron built inside a module.
One may guess in this messy sketch a servomotor, with a arm (in green) linked to two strings that connect to the moving part of the aileron. The wire to control the servomotor are in blue.
5 Sketch end of fuselage module
Figure 11 shows an idea of an ending module. They should be two, one front and one rear to maintain the central fuselages modules between them. The ending module may be assembled with laser cut parts and 3D printed one (the cone) to cover the laser cut parts.
In figure 11 the two top blue lines are one rope going trough the left top carbon tube and back trough the top right carbon tube. Pulleys and a gear are used to put this rope in tension. same is done for the bottom rope. It should be easy to lessen tension of the ropes, then free the rope from the gear and remove the tip modules and central modules.
