he Air Force and Boeing has demonstrated the ability to release munitions from an aircraft weapons bay while the aircraft flies at high supersonic speeds. According to a Boeing release, during a recent test at the High-Speed Test Track at Holloman AFB, N.M., researchers from Boeing Phantom Works and Air Force Research Lab employed “active flow control” with a rocket sled to test the release of an Mk-82 Joint Direct Attack Munition at Mach-2. AFRL program manager on the effort, Jim Grove, said this innovative technology “will enable safe separation of weapons from weapons bays of future high-speed aircraft.” He also commended the use of the rocket sled as “a lower risk technology evaluation alternative to flight testing in this complex, high-risk environment.” The program is called High Frequency Excitation Active flow Control for Supersonic Weapon Release, or HIFEX for short.
The Pentagon on March 30 announced a a $3.8 billion contract modification to buy F135 engines for the F-35 Joint Strike Fighter from contractor Pratt & Whitney.
