Can Weather Balloons Launch Rockets?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of using weather balloons to launch rockets. Participants explore the concept of attaching multiple weather balloons to a frame that supports a rocket, considering factors such as altitude, temperature, and fuel type. The scope includes theoretical considerations and practical applications of launching rockets from high altitudes.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant proposes using several weather balloons to lift a rocket to a certain altitude before launch, questioning the effects of low temperatures on liquid fuel ignition.
  • Another participant suggests that launching from altitude can reduce the total fuel needed to reach orbit and mentions that balloons can reach higher altitudes than initially indicated.
  • There is a suggestion that air launches from airplanes might be a more effective method than using weather balloons, as they can provide more precision and initial velocity.
  • A participant shares links to existing concepts and resources related to the idea, including a reference to "rockoons," which are rockets launched from balloons.

Areas of Agreement / Disagreement

Participants express differing views on the practicality of using weather balloons for rocket launches, with some supporting the idea and others suggesting alternative methods. The discussion remains unresolved regarding the best approach.

Contextual Notes

Participants have not fully explored the implications of temperature on fuel types or the technical challenges of balloon-based launches. The discussion lacks detailed analysis of existing systems or empirical data.

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?

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.
