B What Are the Advantages of Single Stage Rockets Over Multi-Stage Rockets?

AI Thread Summary
Single-stage rockets offer advantages in terms of low cost, simplicity, ease of transportation, and self-contained launch facilities, making them suitable for specific applications like educational bottle rockets. While multi-stage rockets are generally more efficient for reaching higher velocities and longer distances, single-stage rockets can outperform them in scenarios where weight and operational simplicity are prioritized. The discussion highlights that a single-stage rocket can achieve a higher final velocity if the mass of additional stages exceeds the mass of the empty first stage. Users are encouraged to analyze specific scenarios and calculations to understand the trade-offs better. Overall, single-stage rockets can be advantageous in particular contexts despite the general superiority of multi-stage designs.

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
 
Thread 'Is there a white hole inside every black hole?'

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Is Gravity an entropic property like Surface Tension'

Why do two separately floating objects in a liquid "attract" each other ?? What if gravity is an emergent property like surface tension ? What if they both are essentially trying to *minimize disorder at the interfaces — where non-aligned polarized particles are forced to mix with each other* What if gravity is an emergent property that is trying to optimize the entropy emerging out of spin aligned quantum bits
