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!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID 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. Every one of those 2020 conclusions has turned out right.
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
