You have good intentions but do not have much information. The Som - Atmaca engine is a cruise missile engine, so its life is short, it does not require high metallurgy. TEI manufactures parts for turbine engines for world giants and is already testing the Turboshaft engine and will deliver it for field tests this year.
Sorry for late response,
I know already that cruise missile engine doesnt need to have long life span since it will be crushed not long after the missile is launched.
The engine indeed doesnt need high metallurgy but you forget about thrust component. If they can build enough engine power with sufficient thrust for cruise missile, they have better possibility to make higher thrust engine for jet fighter, they can later outsource the material from other companies who have better metallurgy knowledge like TEI to make it has better endurance. So it should be a cooperation between different companies.
There is reason of why Kale is appointed as the one who will develop SOM cruise missile engine. I dont have any problem whether it is Kale or TEI or any one else but the one who is currently developing and design SOM missile engine should be the one who will develop TFX jet engine.
Here is the history about F 5 jet engine.
Design and development
The J85 was originally designed to power a large decoy missile, the McDonnell
ADM-20 Quail. The Quail was designed to be released from a
B-52 Stratofortress in-flight and fly for long distances in formation with the launch aircraft, multiplying the number of targets facing the
SA-2 surface-to-air missile operators on the ground. This mission demanded a small engine that could nevertheless provide enough power to keep up with the jet bomber. Like the similar
Armstrong Siddeley Viper being built in England, the engine on a Quail drone had no need to last for extended periods of time, so therefore could be built of low-quality materials.
The fit was a success on the Quail, but again like the Viper it was later built with normal grade materials and subsequently used to power small jet aircraft, including the
Northrop T-38 Talon,
Northrop F-5,
Canadair CT-114 Tutor, and
Cessna A-37 Dragonfly light attack aircraft. More recently, J85s have powered the
Scaled Composites White Knight aircraft, the carrier for the
Scaled Composites SpaceShipOne spacecraft, and the
Me 262 Project.
