Sagrad has spent four years collaborating with NASA, the Air Force, DARPA and the FAA to develop our first multipurpose AFTU which is now in flight qualification.
Initial qualification testing was completed in late-2018. Technical performance through the test sequence revealed no performance issues.
Final inspection uncovered a mechanical issue isolated to one specific component – a through-hole capacitor. We have chosen to improve the design with an appropriate surface-mount capacitor, with no other changes to the current design. This improved board design will be part of a new series of qualification tests; there is high confidence in the successful completion of this qualification based on the success of the initial qualification.
The re-qualification effort began in mid-Q2 2019 and has remained close to the original schedule. Completion of qualification is anticipated in early Q3 2019.
QUALIFICATION TEST SEQUENCE
The qualification testing sequence includes:
- Full Performance Verification
