Possible Second Design Idea:


Compression Bolt, Instead of a bolt separating from the expansion from heat. Why not use the assistance of the temperature of space. Under direct sunlight or in the shade of Earth.


A somewhat modular design, changeable to be more sensitive for the temperatures of the freezing of space in the shade, or the heat in direct light. Reducing power requirements to change the bolts required temperature for the separation of components.

Submission Notes:


I have gained a keen interest in the prevention and removal of Space Debris over the last year from completing my 4th Year Individual Project at the University of Strathclyde.


Within this project I designed a low-cost 3-Unit active debris removal CubeSat, capable of preventing further satellite collisions and damages. Through missions for deorbiting or repositioning debris, focusing on the region of Low Earth Orbit.


As I have completed a past project of providing a solution to a global problem, I am excited to start a new project which narrows down the focus point to preventing one of the causes of small space debris, such as Payload Separation.

Even though there are already solutions stating that they do not add to existing debris, I believe it is important to innovate on already existing solutions. From doing this, newer and more efficient methods can be discovered, and even if the effectiveness of solutions do not exceed those of competitors. Technologies combined can be refined and may be able to provide a use in other industries.

Initial thoughts...


A thermal collar that is simply composed of 2 or more materials or layers. Each with different expansion rates. The material with the lower expansion rate is to be the load bearing material, or at least the one with main contact of the two objects that require separation.


When heated from a heating element or wrap, the material with the higher expansion rate causes the other load bearing material to break along a pre-determined break line. Separating with little force.



This will be modelled as a proof of concept, rather than a final design. Calculations and simulations may be limited to what I can achieve without dedicated software on a laptop, due to COVID-19 isolation in my bedroom away from the office and family members. I will however, have access to Autodesk Fusion 360., where the majority of the design will be carried out.
