Heliosynchronous Debris Field
I got to thinking about this while dreaming up a ACS/Booster scheme for my space station project.
I am using some of the modules I found at Francophone to build a station, and most of them use the CBM docking adapters. I can very hazily recall watching on NASA TV one night as they attached a logistics module to the ISS, and if that memory serves me correctly they bolted (screw jacks?) the thing into place after mating the two sections together.
So I am wondering now how well a CBM attachment would hold up under real life thrust stresses, from say a pair of Tranzit tugs. I think that it would handle compressive load well because there would be more structure ahead of it, but I wonder about the shearing stresses that would need to be endured by the connections of any modules I have docked laterally along the sides, or vertically along the top/bottom.
Please forgive my bad fizzicks
lol.
Any takers? I promise I won't bite.

Here is a screenie to give you a better idea of the station I am building. Prograde is to the left, with Earth being well below the image.
I am using two Tranzit tugs for attitude control, and they line up beautifully so that both will maintain the same orientation while connected to the station (this also keeps the truss laid down flat). The vertical Neesys modules will hopefully be connected in a more solid fashion later on, with a new spine built between them. But what would happen to the CBM connections if I suddenly threw 80kN of forward thrust into the central mass? I keep thinking that with all the mass overhead (or under, in the case of the ventral mounts) that the CBMs would tear apart at some point.
Hope this makes sense. :tiphat:
