That post was not a detailed engineering discussion.
J79 has more potentional upgrading options to work on, such upgrading to twin spool 3th generation turbojet.
I don't think you are more familiar than me with what going on iran in turbojet upgrading projects.
I am ready to discuss about j79...
All of Iranian F-4 equipped with Iranian modified j79
Which is better than Al21f .
Modifications ,,/
Inlet temperature of turbin increased to 1100 degree centigrade
Compressor blade (shape and material) changed to inject more air
Ignation box (insulation and nozzles,) modified to carry...
We should base a modern inhand platform such mig29 and define new project that inject f14, f4, f5 and .... Features on it and stealth feature also.
Qaher is :
Small but installing j79 or Al21 on it with size up-scaling give more power than f20 or Pakistanian jf-17 or f16 also in single engine...
Turbine inlet temperature of Al21f3 is more than j-79 and it because of kind of Thermal barrier coating, coated on Al2qf3 turbine blade.
So increasing turbine inlet temperature of j-79 convert it to high performance engine.
F-20 manufacturing is not cheap also but for A2A role is good choice.
Look at what Iriaf thinking in this maket.
Q
Qaher is a modified F-5 with a weapon bay under it which can change landing gear location also.
Very good solution which with this Technic a Qaher can be based on F-4 also.
Some problem should solved in F5 such as:
1-Landing gear location
2-Radar low space
3-Mid wings instead of low wings
4-Operating range
F-20 is not a solution but jf-17 may be better.
1-More hardpoints
2-Bigger radar
3-More range
4-More space for future upgrade
5-Economical
Better than f-20...
