Hey JP -- how did you design the propellers? I was curious about how one would design a propulsion system for these altitudes and considered unleashing a 3D panel method on some sample profiles with really low free-stream densities. Curious to see how you got started and manufactured them.
It really did steer and even thrust forward. We've had these propellers to 80,000 feet before. They're design specifically to work in that environment. They really kicked!
thanks for the reply. From the video it looked like the vibrations caused the motion, but realy no critism. I realy admire your work and studied it for weeks since i got struck by an idea to break the hight record thats standing for 40 years on 174.000. feel will contact you soon to share ideas hear your opinion. I was thinking 200.000 feet... by balloon and homebre equipement..however i need to refresh my boyles laws etc before waisting your time with crazy ideas.
Hi John , Does it really steer at that altitude and low air pressure? After all a propeller is kind of a wing mechanism which requires air. Perhaps compressed gas (from balloon) has more effect. Put tubes on the frame and gyro controlled valves to keep platform steady... just an idea
You can check out the launch videos, pictures and hundreds of building and prelim test images and video. It's all on our youtube channel and JP Aerospace website. It would have been really hard to CG all of that plus the 9 hours of flight video from the three cameras and two independent GPS telemetry tracks and the 20 witnesses including independent media folks who were there and watch it on the downlink.
If you've seen our bad graphics you would know we couldn't do the CG stuff. :)
How much thrust were the propellors able to provide at that altitude?

It seems in the space race that people with the least amount of money our doing the greatest things.

@iRobii ... You can do that... but with a payload of maybe 4-5 pounds. Try doing witha 30+ pound payload. It's a bit more difficult.
Shout Out to JPAerospace for using our Kaymont 3000 gram balloons!!!!

@iRobii Yeah this is a controlled airship, not a weather balloon with a camera on it idiot.

There seems to be a balancing issue with the propellers. Nice view!
