Employment of SHM systems for aircraft structure monitoring

SU-22 polish aircraft

Activities in the field of shm:

  • Advice and consultation for appropriate positioning of sensors on aircraft structure
  • Development of new methodologies and applications
  • Development and use of experimental SHM/NDT systems based on ultrasonic (UT / PAUT) and eddy current array (EC/ECA) principles for laboratory health monitoring of aircraft structure, development of assistive software for experiments
  • Development and use of experimental SHM/NDT systems based on electric resistance tomography (ERT) principles for laboratory health monitoring of aircraft structure, development of measurement software for ERT experiments
  • Development and research in the area of structural health monitoring using
    surface ultrasound waves (UGW - Ultrasonic Guided Wave) both metal composite structures
  • Research on application of embedded optical fibres in the forms of Fibre Bragg Gratings (FBGs) for structural health monitoring and inspection of composites
  • Development of use of NDT methods using acoustic emission (AE) for research and development projects
  • Wireless tracking of structures, identification and measurement of damage by optical methods
  • Data acquisition and analyses from voltage sensors during ground or flight tests
  • Software prediction of the service life of aircraft structure using loading spectra generated during the structural testing or aircraft operation
  • Development of experimental devices and fixtures for the non-destructive evaluation of metal, composite and hybrid structures using ultrasound, eddy currents and electric resistance tomography (ERT)
  • Development of software development, methodologies and procedures for non-destructive evaluation
  • Development of software tools for computer simulations of operational and manufacturing damages, e.g. delamination crack growth, impact analysis incl. BVID (Barely Visible Impact Damage), accumulation of damage at manufacturing / operational defects, evaluation of regression models of structural fatigue, etc.
  • Development of tools and technical solutions for repairs, deceleration of damage/crack propagation, efficient bonding and load transfer in composite and hybrid constructions
  • Development of experimental devices and jigs for analysis of damage/crack propagation in composite structures, analysis of crack arrestors (rip-stop doublers)
