Earlier quoted context omitted.
The RTGs on the Voyager spacecraft weigh 38kg. They initially produced 160 Watts. That sounds like a no-go to me.
It might not have great power density but boy does that thing keep going for decades

#13Here's another fun one: https://en.wikipedia.org/wiki/Supersonic_Low_Altitude_Missil... An unmanned nuclear-powered ramjet designed to spew warheads, with a predicted range of 116,000 kilometers.

#15As far as I can tell, aircraft and space nuclear propulsion still hasn't actually be used in flight, right?
Re: General Electric HTRE-3 Nuclear Jet Engine
#16I wonder if a RTG could produce enough to run an electric quad or optocopter? For certain applications if unmanned you wouldn’t really need to worry about shielding. I wonder how long those motors can run continuously?

Other hand Pu-238 produces 570 W/kg. A piper cub with it's 48kw engine would need 87kg of Pu-238 to produce the same energy.
I looked up the cost, $1968/g. So 48kw would cost $171 million.
Interesting idea but doubt.

And for scale that’s circling the earth three times.
