Hot on the heels of the announcement that the F-35A had completed its air restart testing and was moving on to angle of attack (AOA) testing comes the announcement that the B variant (STVOL) has also completed its air restart testing:
The short take-off and vertical landing variant of the F-35 Lightning II Joint Strike Fighter successfully completed a major prerequisite test for in-flight performance Aug. 15.
BF-2 completed the first air starts, which test the ability of the F-35’s propulsion system to restart during flight. Verifying the restart capability of the propulsion system is part of the initial flight test program for the F-35 and a prerequisite for high angle-of-attack testing, scheduled to start next year.
Using multiple restart methods during the tests, BF-2 successfully completed 27 air starts at various altitudes.
With the successful completion of that testing, another variant moves on to AOA testing.
