Can Weather Balloons Launch Rockets?

Click For Summary
SUMMARY

The discussion centers on the feasibility of using weather balloons to launch rockets by attaching them to a frame, with the rocket positioned at the center. The concept suggests that multiple weather balloons could elevate the rocket to a significant altitude, potentially addressing concerns about fuel ignition at high altitudes. However, participants note that air-launch systems, such as those using airplanes, are currently more effective due to their precision and ability to provide initial velocity. The idea of collaborating on this project in the UK is also mentioned.

PREREQUISITES
  • Understanding of rocket propulsion systems, including liquid and solid fuels.
  • Knowledge of altitude effects on fuel ignition and performance.
  • Familiarity with air-launch systems and their advantages over ground launches.
  • Basic principles of buoyancy and atmospheric pressure related to weather balloons.
NEXT STEPS
  • Research the principles of rocket propulsion, focusing on liquid vs. solid fuels.
  • Explore the concept of air-launch systems and their operational advantages.
  • Investigate the physics of weather balloons and their maximum altitude capabilities.
  • Look into existing projects or collaborations in the UK related to rocket launches from altitude.
USEFUL FOR

Aerospace engineers, hobbyist rocket enthusiasts, and individuals interested in innovative launch methods for space exploration.

I have been thinking, weather balloons can go quite high (some up to 1000ft) so would it be possible to take 4 or 5 weather balloons and attach them to the corners of a frame. in the centre of the frame would be a rocket ready to launch at a set altitude. the only problem i can think of is would it be too cold for liquid flue to ignite at that altitude (so maybe solid flue?) any way what are your thoughts. if this idea has any merit then are there any people in the UK who would like to collaborate to get it off the ground so to speck?

i did have a little look on the net but i came up empty

Launching from altitude saves on total fuel required to reach orbit. Balloons can go much higher than you indicate. But so far, taking an airplane ride for an air launch seems a better idea. A few systems have done that. They can be placed with more precision and they can impart an initial velocity in approximately the right direction.
