Sustaining High Gs at Higher Airspeeds

hawker111 · February 18, 2018

What exactly causes a fighter aircraft to sustain high G turns at higher airspeeds?

For example, let's say you have a jet fighter than can sustain, say, 7 Gs at 500 knots, but if the fighter started the 7 G turn at, say, 425 knots it would not be able to sustain the 7 G turn, but would bleed its airspeed down. What exactly causes the fighter to sustain the 7 G turn at the higher airspeed?

Is it:

1) A lower AOA at the higher airspeed
2) At the higher airspeed a jet engine produces greater thrust
3) A combination of both 1 and 2

Thanks,
