Rather than taking a relatively inefficient design and translating it back to being used for something simple why are we reinventing the wheel and gold plating the tread?

Just use electric motors powered by the reactors. Basic, plain motors will do everything you need for any prop plane. Even with the earliest teotwawki you could make high powered brushless motors available so you get good efficiencies. The ONLY benefit provided by jets is they are small and light FOR THE VERY HIGH POWER REQUIREMENTS TO GO FAST. If you are talking OV-10s, C130s, CH-47s etc. electric motors will work fine, brushless will make them small light and efficient and you don't need handwavium to make them work. You would only need jets if you have to go near sonic or faster. No one else is doing that and I do not see any need for TMP either. Especially as high subsonic will get you there and reactors have all the range you need. If you just have to have fast look at the Tu-95.
