Re: Accelerating the wrong way ?
"the engine is slowing it down"
OK - I do a mini-simulation in my head, and I see air going into some kind of 'scoop' device, like what you might see on a ramjet [only a "space" version], and I consider a few things that aerodynamics might cause some trouble with:
a) when the air enters the scoop, how does it get collected exactly? [you need some kind of compressor pump I'd think]
b) while air is collecting for a compressor pump intake cycle, wouldn't it build up enough pressure to exert an impulse on the satellite, causing it to slow down just a bit more?
c) is the electrostatic acceleration going to be ENOUGH more than the (effective) drag caused by the intake scoop going to be enough to overcome the additional drag of the satellite itself against the atmosphere? [this includes the solar panels, too, which just might not be all that streamlined]
I imagine the rocket scientists have thought all this out. Hopefully I didn't just poop their party.
