High-Level Project Summary

This year we participated in the NASA Spaceapp challenge for the first time and we are very excited about it. Our Project was "Let it Go". For this reason, we have developed a device that can cut cables smaller than 12 cm. The most challenging issue for us was that it had a working rate of 99.5%. For this reason, instead of a device containing electricity and electronics, mechanical; In particular, we designed a system with static forces. We used spring systems for static forces. The working technique of our system is as follows; There is one large spring in our system, this spring is preloaded by the user while on the ground and is released when desired by the relay.

Detailed Project Description

This year we participated in the NASA Spaceapp challenge for the first time and we are very excited about it. Our Project was "Let it Go". For this reason, we have developed a device that can cut cables smaller than 12 cm. The most challenging issue for us was that it had a working rate of 99.5%. For this reason, instead of a device containing electricity and electronics, mechanical; In particular, we designed a system with static forces. We used spring systems for static forces. The working technique of our system is as follows; There is one large spring in our system, this spring is preloaded by the user while on the ground and is released when desired by the relay.

Our system is completely resettable and requires no external parts. The user makes the system on the ground with the pulley on the lowest ring, so the spring attached to the first ring on the upper side is stretched and accumulates a static load on it. When the system goes into space or at any time, it can be triggered even with the help of a signal from a sensor, allowing the reel to be released and the cable to break at any time. With the release of the pulley at the bottom, while the first ring goes up, the scissor system connected to it closes due to the conical structure of the tube they are in, and thus the rope in the middle breaks.

The biggest difference of our system from the methods used today is that it is completely resettable and does not create a shock wave.

Space Agency Data

First of all, we would like to thank everyone who contributed to this study, which was carried out to increase our passion for research and science. Let it Go ! the video was helpful. Then, thanks to the keywords in the articles you shared on the web page of the competition, we learned the terms we never knew and made our research more precise and easier.

Hackathon Journey

This trip was our first experience. This adventure was quite exciting and fun for the team. Even if we have more or less an opinion on this subject, we have never researched this deeply. Thanks to the project, we learned in a more comprehensive way how the parts that descended from space to the earth were downloaded. Although there are many topics, we chose this topic with our team. The reason was that we thought it was a subject closer to mechatronics engineering and we're glad we chose it. The difficulties we encountered were the 99.5% work required for the project. Since the mechanisms used at the moment were mostly electrical, the risk of malfunction was high. But with our team, we designed it mechanically and got positive results.
