High-Level Project Summary
Did you know that various space projects use pyrotechnics to cut a reefing line, preventing the devices from being used again?Many of these devices become unusable after the explosions, and even run the risk of being able to activate earlier than previously planned for the expedition.Well now that will no longer be a problem, with the design of our "Space Incision" device, which will allow the deployment of parachutes without the need to use pyrotechnics, by driving a stem by means of an electromagnet, this stem will generate the impulse separates along with the curl line of the mechanical part.We believe that our project will be of great help in the field of space exploration.

Detailed Project Description
HOW DID WE DEVELOP THIS PROJECT?
Visit our project here: https://mtalaverap.wixsite.com/space-apps-challenge
During all this time in most of the space explorations, Nasa has used pyrotechnic devices to release elements (spent stages, fairings, or cut reefing lines).
This method means that these devices cannot be reused, and even run the risk of being activated earlier than previously planned for the expedition. Such as occurred in the failure of the ARES IX parachute.

Due to this disadvantage of pyrotechnic devices, we have designed a device that performs the separation or cut, without using pyrotechnics.

SPATIAL INCISION, presents the following components:
1. Impulse chamber.
2. Injector base.
3. Stem.
4. Dielectric insulator.
5. Electromagnet.
6. Support with return damping spring.
Source: Own elaboration.
This interesting device is composed in its structure of aerospace aluminum and titanium, materials resistant to low and high temperatures.
In addition, it has a size of 11 cm long, 2 cm in diameter.
Thus, it is a light, small, resistant, versatile and economical device.

SPATIAL INCISION allows to cut or separate a reefing line. When the electromagnet is energized, it will drive the rod that will be in the projectable base, this rod will generate that the return shock absorbers enter the supports making the joined pieces split and the impulse chamber comes out together with the reefing line that is connected to it. In this way, the parts will be disjoined.
The stem will not come out impelled since it will remain magnetized in the supports of the projectable base.
The advantage of this system is that once the electromagnet is actuated and the mechanical separation of the system where the projectable base is disunited with the impulse chamber is done.
It can also be manually reattached.
Fixing the stem inside the projectable base, then proceed to place the impulse chamber by embedding it in the supports with return damping spring of the injector base.
INSTRUMENTS:
To design the 3D model we have used AUTODESK INVENTOR.
Space Agency Data
SPACE AGENCY DATA
We have read in NASA sources how is the process of separation or cutting of a reefing line, also through videos, we have been able to realize the devices they currently use, which helped us to understand its function and take it as a reference.
In addition, we have read about some accidents such as what happened with the ARES IX parachute, which has helped us to make our device in solution to the most common problems that occur when using separation devices with pyrotechnics.
Hackathon Journey
It was an interesting experience, as it made us work as a team and think together a possible and useful solution, besides that, we learned about the common use of pyrotechnics in the separation of the parts of a rocket and that is why we chose this challenge, because, that there is a piece so small in size, but the function and impact of it, is huge in a space mission and also is important to us. Our approach was to seek, from the beginning, to do a good job from which we can explain and publicize our innovative solution to the problem presented in this challenge. And to solve the setbacks, we met through Google Meet in order to coordinate the task of each member and thus move faster in its development of the solution. And to conclude we would like to thank our mentors who solved the doubts we had while doing the project and the guest speakers who shared their knowledge with us through expositions.
