What uses Electricity anyway?

The ones I know,

Rover wheels.

Lights.

Ion engines.

Is that it?

[tryrar]

any sort of probe core as well

[Sirus]

I'm a little surprised that the scientific instruments and antennae don't take electricity.

[Dutchling]

Instruments use electricity if you turn them on. Antennae don't do anything so I don't think they should be consuming electricity either.

[Sirus]

Well, the instruments weren't mentioned before, so...

[Dutchling]

Too little, too late.

You ignorant scoundrel.

Hey Girlinhat, I've been experimenting with your JATOs, and with smaller rockets bicoupler JATOs are extremely awesome. I managed to get my tug core up to 200m/s before needing to dump them!

If you have more than one intake per jet engine, you'll get much more performance out of them. If you can level out before passing the jet's ceiling (which depends on how many intakes you have, 15-20km is a pretty good ceiling) you can get yourself up to orbital speed (2100m/s) quite easily before dropping the jets.

10-12 intakes per jet engine on 1,1 TWR jet only craft can reach 60x40km "orbit" inside atmosphere without any wings or rockets. It's 50-70m/s of stable orbit so after adding some LV-N's ic can be a SSTO with 90-95% mass to orbit.

If you don't feel like having 12 intakes for your engine to fly at 50km, just putting some radial intakes on that vertical design might help, i think, they may provide more air at the velocities and altitudes that it caps out at now.
Might not help either.

Radial intakes are good for slow flight, the problem is they generate enormous drag at high speeds. Since turbojets gain more power with speed up until 1000m/s the effects cancel out, but going much faster than 1000m/s is problematic and going above 2000m/s on radials is almost impossible. For low number of intakes and only vertical JATO (i think) they are almost as good or better than ram intakes, but for horizontal acceleration only rams and circular intakes work well. (engine nacelles generate even more drag while giving less air so even if used as a visual part, it's better to close them off).

What does JATO mean? Jeb's Ass To Orbit?

[tryrar]

Jet-Assisted Take Off. Basically strapping several jet-powered boosters to your rocket

[Sean Mirrsen]

Though I suppose "Jeb-Assisted Take-Off" is a nice spin on the meaning.

Technically these are just jet boosters. A rocket doesn't take off, it lifts off. JATO is an aviation term, usually used on large prop planes. These would be.. JALO.

And yes, there's RATO as well. Those are just the usual SRB boosters.

[Chattox]

What is a good level of acceleration to have while still in the atmosphere? I'm sucking really hard at fundamental rocket design right now.
