家园 大概指的是2008年9月15日的试飞

如果这个没错的话,绝不能小瞧F-35的机动性

Comments on the september 15. AA-1 test flight by LMs chief test pilot, Jon Beesley. The flight was conducted to test performance and handling with full internal weapon stores of 5000 pounds:

I had the opportunity yesterday to fly the F-35 for the first time with the INTERDICTION COMBAT load of 2-GBU 31 (2000# bombs) and 2 AIM -120 missiles. In current fighters there is an expectation of performance degradation when carrying 5000# of ordinance but the internal carriage made any degradation hard to discern.

The acceleration in MAX AB takeoff was very quick and interestingly there is an increase in the acceleration rate above 120 KCAS. The takeoff roll was very near to the 3500’ prediction. Once airborne I came out of AB relatively soon after lift off and continued to climb and accelerate in MIL power in a 10 deg to 15 deg climb attitude. There was plenty of performance. The climb out with full internal weapons carriage was particularly impressive to me.

The climb rate seemed to be only slightly hindered by the stores carriage with climb angles near 15 deg in MIL power while in a 30 deg bank turn back over the field. Very pleasant to see clean fighter climb rates and angles while carrying a combat load. The chase aircraft still required brief inputs into AB to keep up with me. This is especially impressive because the 325 KCAS climb speed is well below the optimum climb speed profile for the aircraft.

We only did a brief handling qualities test point on this mission but the handling qualities with this combat loading were indistinguishable from the aircraft with no stores.

Landing occurred with 4500# of fuel and was easily stopped inside of an 8000 ft. runway length with brake temperatures cool enough to taxi straight back to the hangar.

转贴人加了一个注解说:

Note that 8000 ft. refers to the runway length, not the stopping distance.

Chase was an F-16 with "most powerful engine" and no weapon stores.

Take off fuel was 13000 pounds.
