Re: Introduction

Finally completed the next changes for the ship. I'm calling this "version 3" of the Precariat. Made the cargo hold detachable. Added flaps, elevators, & rudders. Added ion-drives to the wing & tail edges. Added 27 merlin engines to the stern (equivalent to a falcon heavy). Removed the drag surfaces...

Re: Cargo Design

Thanks Ernie. I'll try to let you know via email for major updates. I setup precariat.us.to so I can eventually post files larger than the 200K limit here on the forums. Posted some STL files and the cargo hold to get people started. Have been reworking the ship to have the detachable cargo hold, ad...

Re: Introduction

When a Space Shuttle was working with a 'tethered object' that it was lowering into the atmosphere they found out that somehow electricity was being harnessed in the process and it fried out a bunch of stuff. Is it possible that this phenomena can be used...? Thanks again EB! I had forgotten about ...

3D Printing

I know people have asked for STL files for their 3D printers. I tried creating an all-in-one manifold mesh that could be printed as one part, but it's way too difficult (I'd end up redrawing the entire ship again). I figured I should wait until the final design is nailed down (detachable cargo, etc....

Re: Orbital Mechanics

I failed to mention tangential velocity. On the surface, you're moving ~1000mph. Geostationary satellites move at ~7000mph. Does this contribute to weightlessness even though you're holding the same position relative to earth? What would your speed be hovering 63 miles up?

Re: Cargo Design

Steel cables seem to be the leading solution. So it could evolve into external cargo like the aeroscraft design. http://aeroscraft.com/fleet-copy/4580475518 I was hoping for something more rigid that would "dock" with the ship. That way you could have an airlock between the cargo and the ship. If yo...

Re: Orbital Mechanics

Thanks for the link Eduardo! Good reference for designing the lifting envelope. I was searching for "gravity calculators" and found this. https://www.calctown.com/calculators/acceleration-due-to-gravity-calculation Does this suggest that gravity is 97% at 100km altitude vs. on the surface? Or are ac...
