SSTM

[mariohobbs]

A single stage rocket that'll get ya into mars orbit.

Prove it.

on mobile:

note: I probably could have landed if my transfers were more efficient and it my orbit was more efficient, but I’m not very good with the mobile controls

Why do you use angled engines? You are basically thorwing delta-v away by reducing the effective Isp of the engines (which is really important when building an SSTO)

It looks cooler

Exactly as dio said, it looks cooler; secondly i think that the angled engines are spaced tighter together than 2 normal engines, which makes it more aero-dynamic

I tried a quick test using Normal difficulty on the PC version. Reached a 31/47 mars orbit with 2.18% fuel remaining (dV remaining=205m/s)

hmm, Yeah it seems it doesn't have nearly enough delta V to be a return ship; Eh the point of it was to practice making ships that look less bad anyway so good enough, the thing was only meant to be a SSTO anyways i just happened to make a bit too efficient lol

Try making it 2-stage, 2nd stage 25t fuel tank and valiant engine. I did a test using a rocket of the same mass and payload (actually I added a heat shield and parachute the payload was nearer 5t than 4t). First stage was SSTO (just). Reached low Mars orbit and returned to low eaath otbit and had 725m/s dV remaining. Will try a 3-stage test next.

It reaches Ganymede low orbit with 712m/s remaining (not enough for a return). The three-stage version seems to be close to an optimum staging (<<all stages above each stage>>/<<all stages above + current stage>> =2.92 - close to e).
