Interesting, do you have a link to that paper? I guess the regular engines that are running inefficient fuel cycles to power the fuel pumps aren't too weight efficient either, due to the inefficiencies of these fuel cycles. Interesting why this approach wasn't tried earlier.
- Gibbon1 6y agoTook a bit of searching but I found it again. https://www.aacademica.org/hernan.emilio.tacca/9.pdf https://www.aacademica.org/hernan.emilio.tacca/9.pdf If I remember correctly simple turbo pump feed engines have to run using a lot of excess fuel. Simple designs just dump the turbine exhaust overboard. That represents a fair amount of wasted energy. Advanced designs feed the exhaust back into the engine. I think they also scavenge some energy from cooling the nozzle.
