Discussion Overview

The discussion revolves around the advantages of single stage rockets compared to multi-stage rockets, focusing on specific examples and conditions under which single stage rockets may be more beneficial. It includes considerations of cost, simplicity, and operational factors, as well as performance metrics like velocity and fuel efficiency.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants suggest that single stage rockets, such as bottle rockets, may be advantageous in terms of low cost, simplicity, ease of transportation, and self-contained launch facilities.
  • One participant questions the definition of "advantageous" or "better," seeking clarification on performance metrics like velocity and fuel efficiency.
  • Another participant indicates that a single stage rocket can achieve a higher final velocity if the mass of the second stage and its structure exceeds the mass of the empty first stage, but notes that this can complicate the performance due to the first stage carrying additional mass.
  • There is a mention that single stage rockets might be better for short-distance travel, although this claim is not universally accepted or elaborated upon.

Areas of Agreement / Disagreement

Participants express differing views on the advantages of single stage versus multi-stage rockets, with no consensus reached on specific conditions or metrics that define superiority.

Contextual Notes

Limitations include the lack of detailed mathematical comparisons and the need for clearer definitions of what constitutes "advantageous" in the context of rocket design and performance.

Hello
You have all been very helpfull with all my quistions about multi stage rockets and so, but I am only left with one quistion. I know a multi stage rocket is better, but can somebody show me a specific exambel where a single stage rocket is more advantageable, or link to a website where i can see, that would be great :D
Thanks for all your help

A bottle rocket. It is better when low cost, simplicity, east of transportation and operation, and self-contined launch facilities, are the dominant factors..

If you don't like this answer, then you must define what you mean by advantageous or better.

Hello, yes, i mean when do you get fx. a higher velocity, or using less fuel to achieve the same. I have heard that a single stage rocket should be better when traveling for short distances, it that correct?
Thanks
 
As I indicated in the multi-stage discussion, the single stage produces a higher final velocity if the extra mass of the second stage rockets and mating structure is greater than the mass of the empty first stage. It's actually a little worse that because the first stage has to carry all the extra mass too. I won't reproduce the equations here because I produced the full comparison in a previous post. Just plug in some numbers.

Oh ok yes i see it now, i have been playing around with some numbers, and it makes more sens now, thanks to both of you, and thanks @Cutter Ketch for helping me out with all my questions
hope you will help me again in the future, i really appreciate that you took the time to helping me out with basic question :D
