Global Nominee

Cutter application for parachute reefing line

High-Level Project Summary

The developed device is used as a parachute reefing line cutter. It solves the challenge by avoiding the use of pyrotechnics while maintaining reliability and speed of operations. It is important because it is reusable and does not cause excess debris upon re-entry.

Detailed Project Description

Operative description:

The device operates in a simple and effective approach where a trigger signal is sent to a micro-stepper motor that in return rotates a pin leading to a spring decompression. The spring with its end attached to a blade, when decompressed, cuts the reefing line. The proposed device is effective, shock-free, vibration resistant, and resettable compared to pyrotechnic devices. In addition, it is a low-voltage operation, small and light-weight (less than 1kg).



Components and materials:


Micro-stepper motor

Suitable for working temperatures between (-65 to 175°C) 

Spring

stainless steel 316

Blade

CVD nano-diamond treated allowing for a sharper blade i.e. less power to cut and lasts longer

Cylinder 

scalable, currently 19mm in diameter and mm in length 



Software used:


  • Rhino 7
  • Solid works

Hackathon Journey

The hackathon journey for NASCOM's team started off very excitingly and we wanted to choose a challenge which tested our capabilities within mechanical, and electrical engineering. We identified that the "Let it go" challenge would be well suited to match our ambitions and capabilities.


One of the very impactful events which happened to us during the hackathon was the tropical storm "Shaheen" which made landfall on Muscat on the second day of the hackathon. We were very grateful that the organisers granted a 16 hour extension to the deadline.


As a young team who have only begun working together recently this experience allowed all the team members to feel part of the international space science community and be acknowledged at a local level. We hope to participate in many more challenges in the future.
