Its mentioned there "Typhoon is a similar design philosophy to the F-15C and the F-22A, i.e.. a lot of emphasis on acceleration, climb, 40,000+ feet altitudes and the turn fight..Not so much on the mid-lower altitude, close quarter dogfighting side of the envelope."
Typhoon aerodynamic design is a degenerated version of Russian Ye-8. In Ye-8, at large AoA wind can go through the gap between the wing and horizontal tail to access with the vertical stabilizer. Meanwhile, in Typhoon, at large AoA the vertical stab is blocked by the wing and the hull, and then lost its function.
Therefore Typhoon and other EUcanard can't have large AoA and has very low maneuverability.
Meanwhile, F-15 and F-22 has the gap between horizontal tail and wind. And they have two vertical stabs which are positioned so that they are not blocked by the hull. That configuration is learned from MiG-25/31. That means F-15 and F-22 can achieve great AoA and is good at dogfight.
So is it true that at 40K feel MKI would be at a disadvantage against Typhoon as the latter is optimised for high speed flight and former for subsonic low altitude ?
It is right that Typhoon max speed is slightly higher than Su-30 (M2.2 > M2) and it is right that EUcanard configuration is favorable for forward movement at high speed. But maneuverability of Typhoon is pathetic.
Maneuverability is a distinctive characteristic for air fight, both long range and short range. It enable you to escape the incoming missiles or escape the radar vision of the enemy, etc etc. In air fight, Typhoon can't win against Su-30.
Does MKI has advantage over Typhoon in BVR combat
Su-30 radar is bigger than Typhoon, that means it has better angular resolution.
Su-30 radar is PESA with dynamic shifted phase, that means it has advantage about the cleanliness, purity and quality of the signal, and it can quickly oscillate the radar beam like AESA.
Su-30 has 240 degree radar vision, much larger than Typhoon.
And as far as I know, Su-30's ECM is far superior than the West.
