We experimentally produce, with enamel and graphite, the conductive paint to test its operation, and obtain the expected result. However, the resistance was quite high, so we are looking at other materials that have better conductivity.

Reference for how to make a conductive paint.

The last completed step was to define the material that will be used for our solution, taking into account conductivity, lower cost and lower density compared to the use of copper wires. According to research, the material used will have graphite as a conductor.

According to the calculations performed by the team, the density of the graphite-based material is 12,24% lower than the density of copper. In addition, while both copper and graphite cause environmental impacts from soil exploitation, the amount of graphite required for the material used be much less than the amount of copper required. Therefore, it generates less environmental degradation. And finally, graphite is the cheapest conductor.

According to our research, we find that most light and small aircraft use a 14 or 28 volt direct current electrical system, and larger aircraft use a more complex system, with 28V direct current and other parts.

Therefore, after obtaining this voltage range, the maximum capacity supported by the solution proposed by the team was analyzed and it is only viable for the low power system, that is the control circuit. So from now on, we will focus on that part.

We are researching how well the aircraft's electrical system works and what requirements are needed to see if our solution will match them.

We have already started work here! The first stage happened yesterday and consisted of the analysis of the themes and the qualifications of members. After the decision, we started looking for the solution.

The next step will be to validate this solution.

More updates coming soon :)
