Are you going to post some rules, or am I making the biggest nastiest rocket I can, that still just happens to maintain contact with the ground?

magnetic alignment and orbital maneuver

I'm remembering that the small converter is energy-negative when used with fuel cells. I could be wrong. You might be in for a nasty surprise when you get out to where the solar panels don't function.

Good god, man. I'm definitely going to try that after I finish my revised spaceplane ascent script. I still owe you an answer on the Tylo thread from July. I had about three pages typed up, and then I burnt out.

It's at least partially my fault. Fantastically impressive project, and covers a lot of KSP engineering disciplines. Everybody get off your butts and submit TOTMs per the OP!

No one EVER has esoteric applications in stock KSP. /s The NERVA is largely conceptual (despite some test firings) and abandoned. The SABRE/RAPIER is conceptual. The helicopter scout is scheduled to go to Mars in 2020. That's a long way from conceptual. The logic of your argument doesn't even hold up based on the conditions YOU set. Also, you forgot to add the words the words "precious bodily fluids" to your last sentence.

@Ildon KRPC offers a pretty flexible autopilot system. You could read that list from a file, translate between reference frames, and output the desired heading/rotation. It wouldn't be a "perfect" recreation, but enough to visualize the motion, if you build the craft properly, and tune the autopilot. https://krpc.github.io/krpc/python/api/space-center/auto-pilot.html (Other languages than Python available) https://krpc.github.io/krpc/tutorials/reference-frames.html

Northrop Grumman Innovation Systems (Orbital ATK) thread

Just as a sidenote for anyone who wasn't aware: I've been reading through a lot of material on military hardware, and it's amazing how many weapons contracts Orbital ATK has. -
Stock Boeing Pelican, *HUGE AIRCRAFT*
FleshJeb replied to Kronus_Aerospace's topic in KSP1 The Spacecraft Exchange
I can't tell if I'm deeply impressed by this, or worried about your sanity... EDIT: NOW I notice your role text. -
Uninstall KSP and never play again.

I've watched both your hurricane videos and checked out the KerbalX page. Absolutely top-notch engineering and presentation.

Cupcake's Dropship Dealership...
FleshJeb replied to Cupcake...'s topic in KSP1 The Spacecraft Exchange
I just hit T, Z, and Spacebar and let it get up to 35m/s before I pitch over. Maybe it's a difference in physics/friction/legs between versions (I'm on 1.3.1). I just added some Sepatrons to help you get it off the ground: https://www.dropbox.com/s/veuduygpf3v508c/Bio Falcon that poops.craft?dl=0 I purposely designed this to fly slowly and gracefully, but if you want to get up to @Cupcake... levels of stunting, make the control surfaces more aggressive. Speaking of which, this is Cupcake's thread, and I don't really want to crap it up with my stuff--This craft is just a nod to his extraordinary sense of fun and aesthetics. Feel free to PM me if you have any more questions. Ha! Thanks man! The version posted above must have found some Taco Bell in the KSC's trash cans. It's got some fire coming out of its rear. -

I have a million-and-one snarky answers to this, but I'll give you the straight one : -

what's the dumbest mistake you've made in KSP?
FleshJeb replied to TimKerbin's topic in KSP Fan Works
If it makes you feel any better, I understand that KJR is roughly the equivalent of turning on Autostrut: Grandparent for every part. Technically, that's stock behavior. Personally, I try to only autostrut in limited places. because it ALMOST feels like cheating, and it does increase the physics calcs a bit. -
That's actually almost correct. You DO get more work out of the same mass of fuel. The only reason it's not correct is that Delta-V is specifically designed as a "mass-agnostic" term that provides an versatile benchmark for comparing what you can do with various spacecraft. It still matters how and where you apply it. Much like ISP is a generic benchmark for comparing engines, but TWR is an additional factor to consider in design and piloting. I don't have a perfect understanding of this myself, and I hope @sevenperforce will correct anything I've gotten wrong.

I'm going to commit a travesty of physics by oversimplifying this explanation: Kinetic Energy = K = 0.5*mass*velocity squared = 0.5*m*v^2 Lets say we have an orbit where the speed is 2200 m/s. This is roughly a circular Low Kerbin Orbit. v1 = 2200 m/s, so K1 = 0.5*m*2200^2 = m * 2,420,000 Now we have another orbit where the speed is 2000 m/s. This is a slightly higher, but still fairly-Low Kerbin Orbit. v2 = 2000m/s, so K2 = 0.5*m*2000^2 = m * 2,000,000 What happens if we do a 100m/s burn at either of these two points? (We'll play with infinite fuel on, and say that m doesn't decrease; it would decrease by the same amount in both examples anyway.) v1' = 2200 + 100 = 2300, K1' = m * 2,645,000 v2' = 2000 + 100 = 2100, K2' = m * 2,205,000 K1' - K1 = delta K1 = m * 2,645,000 - m * 2,420,000 = m * 225,000 K2' - K2 = delta K2 = m * 2,205,000 - m * 2,000,000 = m * 205,000 delta K1 / delta K2 = 1.098 Same magnitude of burn, same delta-v expended, but you get almost 10% more energy from the burn. Is it free? No, because you're changing the energy of the fuel you're blowing out the back by more as well. Since orbits are really defined by how much energy they have, you can go "farther" for the same amount of fuel, by burning lower. Hopefully that takes some of the black magic out of it.

Lowest cost per ton to Jool Intercept
FleshJeb replied to KerikBalm's topic in KSP1 Challenges & Mission ideas
I'm curious as to the rationale for that rule. My most efficient spaceplanes in 1x scale typically start with a closed-cycle TWR of 0.2, and as a whole, only get above 0.8 TWR when the open-cycle Rapiers are near full performance. This won't work as well in 3x, but you'd be shocked what you can get to orbit with a ridiculous amount of wings. -

Top-notch moderating @Deddly. You and the rest of the mod staff are one of the primary reasons I value this community so highly. -
Redneck Space Program: Complete with lifted 4x4, trailer, and two waverunners. Perfect for hooning about and mudding. The 4x4 is fully submarine capable. This is what happens when you mix rednecks and radioisotopes. AG1 to roll coal, AG2 for the waverunners. https://www.dropbox.com/s/b2cgi9amyq4oqlc/Redneck Hoon Program.craft?dl=0
