Gravity turning is not more efficient in KSP but it gives bonus realism points.

it is

it even has oberth effect

[Aseaheru]

is there Coriolis effect?

[LoSboccacc]

before the first optimization update, there was the tidal effect and larger longer craft got tidal locked with kerbin

[Aseaheru]

  woah..... but still, is there coriolis effect?

[LoSboccacc]

woah..... but still, is there coriolis effect?

ok I had to check this up because I couldn't remember how Coriolis worked.

yes there is, and it is the reason every orbit is more efficient when starting at 90deg

[Aseaheru]

ah. ok. just checking!

Nah, if it was kerbal engineering, the whole thing would have exploded.

[Aseaheru]

woah..... well, that must have been fun for whoever built that one... and the crew who installed it, and the crew...

[Peewee]

It wasn't a manned launch.

Gravity turning is not more efficient in KSP but it gives bonus realism points.

Considering max speed in lower atmosphere, we have found with tests to be about 200m/s.
Just because MechJeb goes to 100 m/s does not mean that is most efficient.(I consider mechjeb cheating anyways)

I'd recommend doing 2 test with the same rocket, one going at 100 m/s and one going 200 m/s in the lower atmosphere.

I disagree, "gravity turning" is actually benificial due to 1. oberth effect 2. centripetal force acting erlier thus , less energy lost from gravitational pull.

Actually let's do a challenge KSP 0.17

Small command pod (mk1)
4x FL-T400 fuel tank
LVT30 engine

How much fuel can you get into orbit (above 70km)
My first attempt, 16,8L of fuel left, can you do better with your ascent profile ?

The Deep Space Kraken Cthulhu tore off the engine.

I think I've figured out what's wrong with my rocket currently.

Engines forward of the center of mass just plain don't work right.

[Sean Mirrsen]

Engines forward of the CoM tend to blow exhaust into the rest of the craft if not positioned properly.

[Rose]

Not just that, but the they also seem to steer it in the wrong direction. Or at least the craft tends to be very unstable in gneral.
