But wasn’t the core engine being developed for Airborne vehicles. Atak, gokbey, hurjet, mmu and such.
How can the same core engine be used for land vehicles ?
The only difference between the turboshaft and turboprop engine is in the power transmission. In fact, the tanks should theoretically use a turboprop engine, not a turboshaft, because the power transfer is transmitted horizontally to the engine, but in airplanes like Hürkuş, the part where the power is transferred and the part where the air is taken must be used from the same place, ie the front part. For land vehicles, if you use the TS1400 in turboshaft mode and reverse the part where the air flow is provided and the part where the power is transferred to the gearbox as it is now, you can use it in the same way, you don't need to produce a new engine from the core engine from scratch.
