And what makes you think that?
TAI KAAN has approximately at least the first prototype would have 27 tons as take-off weight, if fully fueled and loaded with ammunition, at least in theory.
Both GE F-110-129 Engines each have a dry and wet thrust of 76KN/131KN.
TAI KAAN
To calculate the thrust-to-weight ratio for the TAI Kaan with two engines and a maximum takeoff weight of 27 tons, here are the details:
Given Data:
1. Thrust per engine: General Electric F110-GE-129
With afterburner: 131 kN per engine
For two engines:
View attachment 72716
Result:
The thrust-to-weight ratio of the TAI Kaan is approximately 0.98 at maximum takeoff weight with full afterburner thrust. If the aircraft operates at a lower weight (e.g., reduced fuel or fewer weapons), the ratio can exceed 1.0, improving acceleration and maneuverability.
F-22
To calculate the thrust-to-weight ratio of the F-22 Raptor when fully fueled and armed, we need the following data:
Given Data for the F-22 Raptor:
1. Engines: Pratt & Whitney F119-PW-100
Thrust per engine (with afterburner): 156 kN
Total thrust for two engines:
View attachment 72717
Result:
The F-22 Raptor has a thrust-to-weight ratio of approximately 0.84 when fully fueled and armed (at its maximum takeoff weight). This value increases significantly when the fuel load decreases or the aircraft carries fewer weapons, often exceeding 1.1 in combat configurations with partial fuel and weapon loadouts.
TAI KAAN probably uses more composite, titanium materials than the F-22, The Second KAAN Prototype will probably be somewhat smaller and more delicate, probably 6-8% Lighter then the first Prototype.
We would then be talking about a thrust ratio of 1.10/1.20 and that is more then the State of the Art.
KAAN is actually an air superiority fighter with multi-role options. But it is not a bomb truck like the F-35 which is superior against other GEN 4+ aircraft but I doubt it has a chance against a J-20 Chengdu SU-57 at least in dogfight provided the radars of both aircraft have the F-35 under control.
