More News on Project ThunderStruck
Thanks for the support in both contributions of dollars and more importantly at this stage, getting the word out and helping with services. Tim Gagnon is a fine graphic artist from Florida and he has pledge support by offering to design the mission patch. If you have any thoughts about his skills, have a look at his website. I believe that he has done one or two before!
Spending Your Contributions
Now a little detail on how we will spend your contributions. I did say it would cost $80,000 and that was no exaggeration. For a start there is about $10,000 worth of electronics to buy and test for the final flight and that is just the TV link, the telemetry, the control system for flight, cameras, video from the balloon to see the aircraft and the release, the tracking systems for the balloon and the tracking for the aircraft, the balloon flight termination system. The balloon for the final flight will cost over US$10,000 and the helium will cost $3,000. We will have to buy 2 radar transponders to warn aircraft of our position and they cost $2,000 to $5,000 each (and are heavy too).
Every two weeks we will do a weather balloon flight to test the latest systems for Project ThunderStruck and these will cost between $1,000 and $2,000 dollars each and take up our whole weekend traveling and staying in hotels. Petrol alone costs us $300 for the trip and launching and recovering our systems. Below is a video of a launch we did in Croatia. You will see that it is very difficult and requires a lot of materials and you don’t always recover them. So far we have recovered 100% of our payloads, but one day….
The airframes will be expensive and we will need two. Jason has said that since most of our antennas are internal, the airframe cannot be made from carbon fibre alone or the signals will be severely attenuated. He will also need to have sections of the fuselage and possibly parts of the wing fabricated from a material such as Kevlar.
The picture, right, is an antenna that may be on the aircraft and shows why we must locate it inside of the airframe. It is a little fragile to leave out in a 1,800kph airstream!
CASA – Australia’s Civil Aviation Safety Authority
Our Civil Aviation Safety Authority will also likely want us to travel to a remote part of the country for the big event. That will probably be one of our biggest costs – transporting all that gear and setting it up in the middle of nowhere and that is not a two person activity. We will need transport and accommodation for a huge crowd of people.
I look forward to telling you more about the technical parts of the mission in the next update for Project ThunderStruck.
