The rail gun: a cheap solution for getting payloads into orbit quickly.
The rail gun: a cheap solution for getting payloads into orbit quickly.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

Sounds a lot like John Hunter’s Quicklaunch,which utilizes a gas gun. Hunter believes he has the solution to some technical problems associated with launching a high velocity object in the lower atmosphere. There’s not much mention here on that problem.
But the military has deep pockets, so he may that problem handled.
launch is under terms of Lift. re entry Has always been a ratio of conditions as to rate of Fall in regards to friction encountered. the same as drag coefficient calculations regarding Brake Systems that most of of us easily understand. a by product of this unit of friction is indeed Heat. and therefore, ridding the proposed structure Of.
Actually this doesn’t deal with any of the issues of launch costs as far as I can see. It would likely make them worse since few loads could take its high G and thermal loads, hence exacerbating the fixed cost vrs low market demand issue that dominates launch costs.
Same way space Elevators would likely drive costs to orbit way up compared to rockets – (potentially tens or hundreds of times more with a similar market size).
interesting points Kelly, however, in respect to you. please have a look at replublicbikes.com as to mastering any of your own design levels of achievement. fancy yourself a spartan amongst the basics. and after , oh ….lets say 30years of direct contact with hardware beginning with the parabolic cone dimensions of nozzle design parameters in regards to nozzle velocities that produce desired thrust per seconds over a prescribed duration of load. equals a witty come back : i can Only hope.
not being mean, but i know where we can get some rather Spiff beanie caps with awesome revolving propellers affixed to their crowns
