Unpopular opinions, for short and mid. term planning:
-New production Tb-2s should be modified to use PG-115s in mid term.
*Proven, reliable engine, why not to use. Changing Rotax 912 architecture to Rotax 914 architecture is not that a hard thing imo. They constantly upgrade Tb-2, this should also be in their change log imo.
- Hürkuş - IIs and a variant of Akıncı should mated with TP1400+.
* PT6 alternative, probably would be more fuel efficient and would have more power at higher altitudes, my amateur speculation. Because it's a newer engine. Both Hürkuş - II and Akıncı would enjoy more lift / more loitering time / more power at higher altitude. KT-1Ts are can hold the line years more. Hürkuş - II can become online with new engine, after developing the plane with PT-6.
- T625, T629, T925 and T929 should use TS1400+ with double/triple engine configurations. At least to the 2030s. Then a new 3000shp engine should became online.
*Mr. Akşit says the engine it reached 1571 shp continuous power. Our TEI build T700s have 1700shp continuous power afaik. Three of these should be sufficient enough. But of course, nothing will be better than 3000shp with2500+shp continuous power engine. But it's backlogged behind TF10k. TS1400 will also have EASA afaik, so it will be a proven mature engine. And common engine among our helicopter fleets would be both maintenance & cost effective. Again, at least to 2030s, until TS3000 becomes online with new variations of T9XX helicopter series.
-Every kind of variation of TF10k should be created. Naval turbine, natural gas chamberers, generators, civilian turbofan engines, etc.
* LM500 is in not active production much afaik. New opportunity for TEI and GE Marine. Industrial and civilian aviation versions would also create more income and more flexibility. Especially if we talking about national regional airliners.

**Why i'm writing these.. TEI will need more funding. For 5th,6th, etc. gen engine R&Ds. It should supported with more sales. And for growth.
*** I couldn't find the proper thread in this forum. Propulsion thread would be better but these are contains lots of what-ifs. So that's why i posted here in TurAF News and Discussions thread, sorry
