UAV powerplants
(OP)
I'm looking for a suitable powerplant for a small UAV (around 100 lb) for high altitude work, say 30000 - 40000 ft, as part of a design study. I'm currently favouring a 20 hp Limback, as this gives the required hp (~2hp) at altitude unsupercharged, and weighs about 15 lb. Does anyone know of a more suitable engine, or small superchargers / turbochargers which could fit the bill? (Supercharging a model aircraft engine may be an option).

to help get your UAV to ceiling? This would allow you either more fuel or a heavier engine.

Don't forget that Your engine power requirement is likely to be a combination: (a) thrust and (b)aux power. Aux power will be required for cooling, heating, hydraulics systems and electrical system consumption. Even in a small UAV, I presume that electrical/electronic Items may carry a significant current load that is un-sustainable by a battery system!
