Verdon S4 - XXL Interplanetary drive ship

[Jamie Logan]

Hey Y'all!

I hope everyone is enjoying their time in quarantine, as well as staying safe and sanitary. It's certainly given me more time to muck around in KSP, so I've got something new to show.

 

 

 

The Verdon S4 (named in honor of the late Verdon Kerman) is an interplanetary transfer vehicle that can be used to drive large and otherwise massive payloads around the Kerbol system. The design was put together to maximize the final TWR and delta-V when reaching LKO without needing a part count that drives your (or at least my) framerate into a slideshow.

I've included a secondary vessel; a crew habitation module which will act as our payload for demonstration purposes. With room for 28 Kerbals, it also has six docking ports; one large port for docking with the S4, one standard forward port, and four lateral ports to allow for extra vessels to dock (landers, probes, visiting crew ships, etc.).

S4 LKO Vac. delta-V and TWR for various payload masses:

payload mass (t)	delta-V (m/s)	TWR
0.000	6951	0.44
25.000	6288	0.43
50.000	5654	0.41
64.323**	5428	0.40
100.000	4816	0.38
200.000	3760	0.33
400.000	2651	0.27
800.000	1688	0.19
