Composite materials in aircraft wings and control surfaces can be fatally weakened by accidental impacts or environmental incidents, such as lightning strikes. NLA Diagnostics’ simple, fast and effective non-destructive testing (NDT) device is practical for use outside the laboratory to detect damage in composite wing material that is invisible to the eye and undetectable by other methods. Easy to use in the field, the device can reduce aircraft downtime by enhancing routine inspection procedures. At the same time, it can provide rapid, easily deployable “first aid” assessment testing in cases of suspected impact damage.

The “tap test” is the most common field inspection method currently being performed on composite helicopter rotor blades. However, the human subjectivity of traditional tap testing does not detect delamination and degradation accurately or early enough to prevent catastrophic failure. NLA Diagnostics’ affordable, reliable and user-friendly non-linear acoustics device determines the structural health of composite rotor blades in multiple failure modes. It can test for manufacturing defects, failures due to cyclic stress, projectile impact, battle damage, heat damage and other external damage effects that cause delamination and degradation.

Without the use of NLAD’s NDT impact resonance device, maintenance procedures on a single rotor blade can require more than 40 service hours resulting in operational and sustainability costs of $200,000 or more. NLAD continues its drive to create usable technologies that offer the Army, Navy, Marine Corps, Air Force and Coast Guard:

  • Ample resolution
  • A proper readiness level, and
  • Compact, feasible utility in field environments.
