Discussion Overview

The discussion centers on the concept of using a maglifter as the first stage of a space launcher. Participants explore the feasibility, current status, and technical aspects of the maglifter, including its design, propulsion systems, and comparisons to other technologies like railguns and maglev trains.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant seeks reliable sources and current information on the maglifter project, questioning whether it is still under investigation or has been abandoned.
  • Another participant suggests that the maglifter is similar to railgun technology, highlighting challenges in power generation and the potential risks of launching a craft compared to a projectile.
  • A participant describes the maglifter's configuration involving magnets or superconducting coils and a sled, emphasizing the need for further information on its viability as a space launcher.
  • There is a discussion about the design of the maglifter, with references to a ramp for launch and the inclusion of a traditional propulsion system to achieve orbital speed.
  • Several sources are shared, including patents and articles that refer to the concept as a "Space Tram" or magnetic levitation launch assist, although some participants note they have not fully reviewed the materials.

Areas of Agreement / Disagreement

Participants express varying levels of knowledge and opinion about the maglifter's design and feasibility, with no consensus reached on its current status or future potential as a space launcher.

Contextual Notes

Limitations include the lack of detailed technical specifications, the dependence on definitions of terms like "slipper," and the unresolved nature of the maglifter's practical application in space launch systems.

Hi, I am an Italian student of aerospace engineering.
I'm writing a thesis on maglifter as the first stage for a space launcher, but I can't find any recent information.
Do you know any reliable source for my research?
But more importantly, do you know if the project is still under investigation or has been abandoned or are being made experiments?
Thank you very much!

I think you're referring to a railgun-type launcher. The tech is out there, the US Navy got one from BAE back in '08 and I've seen several homemade ones. The biggest problem is power generation and storage. Also, launching a craft would be slightly more difficult than launching a projectile meant for destruction, simply because you can't just turn it on and fling the craft, g-forces would tear all kinds of things up. Like, I don't know, the people inside maybe, lol. Here is a link to a homemade railgun that just fires projectiles. gizmodo.com/.../diy-rail-gun-is-terrifying-comes-with-building-instructions
 
Hi J.ofalltrades, I don't know much about railguns, but the Maglifter is a space launcher...generally with a guide, on the ground, composed by magnets(or SC coils) and a sled (with magnets too or SC coils) on which is put the shuttle (or payload carrier). Its configuration depends by suspension and propulsion systems.
The question is if it will ever use as a space launcher or not... my teacher didn't tell me something about and,this is not a subject of my study, so I'm trying to get more informations I can!
Thanks for your post!

Another question is: what is a slipper (not the shoes)? It has to be a suspension system, but I can't find an italian name for it!

Thanks again!
 
Oh, I get it. Probably a set up like a Mag train, such as the ones in Japan. But this launcher would have a ramp at the end?
 
Yes, it has a final ramp, and when it reach the final speed, it is launched! Actually it has also a traditional propulsor to reach the orbital speed!
 
I found several sources calling this a "Space Tram" or Magnetic levitation launch assist.

Here are some links

Last one opens a PDF. I didn't read all of these because I'm at work, but this should help you track down more links at least.
 
Thank you!
