>Norwegian F-35A Conducts In-Air Drag Chute Testing, Clears Full Envelope
Apr 10, 2018
The F-35 Integrated Test Flight team at Edwards Air Force Base, Calif.
recently completed in-air deployments of the Norwegian Drag Chute System.
The drag chute is unique to Norwegian F-35A aircraft and rapidly decelerates
Royal Norwegian Air Force F-35s after landing on the country's icy runways.
These tests were required in order for the maximum amount of force to be
applied to the entire system. Tests were first conducted 19 March using full
afterburner a few thousand feet above the runway in level flight. When the
pilot deployed the chute under these conditions, the heat from the
afterburner slightly tore the chute and invalidated the test data. The
flight test team reassessed its method to achieve the proper loads. On 28
March, the aircraft deployed the chute while conducting a dive and
maintaining the engine power at idle. This enabled the flight engineers to
collect the data points necessary to complete the in-air testing. Pending
final data review, all drag chute testing is complete and Norway is on track
for full certification of the system by the end of this year.
Earlier this year, cold-weather testing of the drag chute system was
conducted at Eielson Air Force Base in Alaska and Norway's Air Force
validated the drag chute at Ørland Air Force Base 16 February.
