From: apolivka@x102a.harris-atd.com (polivka al 60047) [mod.note: Followups to sci.space. - Bill ] Does anyone out there have any good rules of thumb as to how many watts per pound you can get out of a spacecraft power source? Specifically interested in: - solar (not nuclear) source, - with battery for 24 hour operation, - generation of raw 100 volt power bus only (not regulated power). Basically, what is d(Watt)/d(Pound) in the general region of around 1 kW total power output (i.e. "delta Watts" per "delta Pound"). I need to know the weight to generate the typical raw "bus" power (e.g. at 100 volts), not regulated power. Thus, I'm interested in weight of things like solar panels vs. how many watts they generate, battery, weight of circuitry associated with providing a 100v bus. Not interested in DC-to-DC converter weight. Just looking for a bottom line X watts/lb rule-of-thumb.
