Boeing 777 Diagonal Brace Prototype: 

  • Specimen bearing, thermal cycling tests (2000 cycles) 
  • Impact 'screening' tests (to find visible damage threshold)
  • Full-scale prototype with visible damage:
  • 42,000 fatigue cycles
  • Static and stiffness measured between each test
  • Ultimate compression
  • Ultimate tension
  • Static tension to failure at approximately 3,500 kN (800,000 lbs)


Boeing 787 Diagonal Brace:

  • Qualified in 2008-2010
  • Impact screening, compression after impact, full scale static with impact damage and manufacturing defects, and 3 lifetimes cyclic testing, rough flight testing and rough landing testing.
  • Several million load points running 24-7 over a 3 month period
  • Involved 80+ strain gages, several lvdt's and 8,900 kN (2000 kip) load cell.

Qualification Tests on Aircraft Emergency Locator Transmitter (ELT)

  • All Testing in Accordance with RTCA DO-204 and DO-160
  • Tests included:  shock, vibration, humidity, salt spray, salt water immersion, altitude, rapid decompression and overpressure.
  • Testing of lithium battery packs contained within the ELT’s to RTCA DO-227 and DO-160
  • Tests included: shock, vibration, thermal cycling, humidity, altitude and decompression, bench tests and abuse tests.




Acceleration Testing of high voltage power supplies for an aircraft radar system

  • Tests carried out at an off-site centrifuge facility
  • Tested in 6 directions as per RTCA DO-160







 

Tensile testing of coupons at high and low temperatures.  Three materials tested using coupons previously exposed to 1000 hrs UV accelerated weathering tests and 10 humidity tests.
