Speeding up does not work, that'll just put it in a higher orbit. My understanding of these issues is that introduced eccentricity gets you: if it takes the "inside corner" (is that the English word for binnenbocht/innenkurve?) around the earth, it could then then meet you on the other side where the orbits intersect. If it sped up (flying out of the corner, in this race analogy) and thereby took a longer way around, it'd rather be a danger to those immediately behind (with each orbit, progressively further back along the circular orbital path)
Disclaimer: this comes from playing a self-made orbital mechanics game, I have no training whatsoever let alone professional experience with this
- bryanlarsen 2y agoAny velocity changes will only happen once so will result in an eccentric orbit where only one side of the orbit is raised or lowered -- the other side will still be in SSO.
- panki27 2y agoMy KSP experience supports your view :) Parts that were sped up have their opposite orbital side raised, parts that got slowed will have their opposite orbital side lowered.
- sangnoir 2y ago> Speeding up does not work, that'll just put it in a higher orbit Speeding up doesn't raise the orbit; it makes it (more) elliptical while still intersecting with the old orbit (shared with neighbouring satellites)- you need at least 2 maneuvers to raise an orbit. You're also assuming a perfectly pro-grade acceleration. In an explosion, different pieces go in different directions, I suspect there is a vector that results in faster speed in the same orbit, but I'm no rocket scientist.
- sangnoir 2y agoCorrecting an inaccuracy in the last sentence I introduced in an edit: Kepler's laws means you cant have different velocities in the same orbit - bit its possible for an explosion to cause a projectile to intercept a satellite that was ahead of it in a new orbit.
- pavel_lishin 2y ago> this comes from playing a self-made orbital mechanics game My interest is piqued!
- Aachen 2y agoThanks, but don't expect too much! (In particular on mobile where you can't zoom by scroll wheel or use arrow keys to fly.) I mentioned it in an earlier comment, probably easiest to refer back to that for some context/hints: https://news.ycombinator.com/item?id=35763506 https://news.ycombinator.com/item?id=35763506
- pavel_lishin 2y agoThanks! I'll check this out later today.
