Have you ever wondered where helium balloons go when you let go?
Probably not that far.
But you can modify the balloon so it goes a lot further
- Use a much larger balloon, and underfill it
- Or make the balloon out of a material that’s not going to pop so easily
This is a superpressure balloon
This guy holds the world record for the longest superpressure balloon flight
Student High Altitude Ballooning
Equally Large Budget
Low Weight == Tiny Budget
Ok, this is awesome
What are we doing?
Check out www.marsballoon.com
They’ve asked us to put a paper plane on their flight at the end of October. It’ll go inside the balloon and get released when the balloon bursts at about 30km
They’ve managed to pull off this trick before, but the paper plane didn’t have a GPS tracker. Ours will!
We’ll be close to the world record for the highest launch of a paper plane, although we’re not making it an offical record attempt.
Needs to comply to CAA rules for balloon payloads (<20g/cm^2 from all angles)
The total mass of all elements needs to be <100g
Needs to fit through the 6cm diameter hwoyee 1200 balloon neck
The plane body needs to be entirely made out of paper (paper straws can be used for integrity) with no sharp edges
The tracker weighs about 15g, and it’s about 50mm * 12mm * 20mm with the battery attached. It has wire antennas protruding from either end too.
Deadline: Sunday 12th October? We’ll have another meeting then to judge which one we’d like to use for the launch
Feel free to enter as teams or individuals.
Don’t take it too seriously! We don’t know how to make a paper space plane either..
What else could we do?
- Launch our own pico balloons
- Try to network them
- Try new modulation schemes and communication techniques
- Build a permanent ground station
The pico tracker is awesome because it’s so cheap (~£30) and light. We can afford to fail and loose the tracker!
We could give these away to schools – with instructions and our help – and see what happens….
