Structural integrity assessment of airborne external antenna and active antenna array unit (AAAU)

Uniqueness

  • Complex structure built with components such as antenna, beams, bottom cover, brackets, connector plate, inner duct, power supply unit, TRMM bay, top cover, rear hood, pylon interface, etc.

Methodology

  • Constraint conditions invoked in the integrated finite element model to interface beam, shell, gap and solid element
  • Free vibration analysis to extract natural frequencies and mode shapes
  • Dynamic response analysis under different loading conditions
