Embedded Sensor Processes for Aviation Composite Structures


Develop and demonstrate new manufacturing techniques for integrating sensor networks on composite aviation structural components.


Develop and demonstrate manufacturing techniques for integrating strain, temperature, vibration, and damagedetection sensors in composite structures. Identify adhesive materials and bonding techniques for integrating sensors with composite materials; evaluate current composite repair techniques for incorporation of sensor network repair processes; develop affordable processes for manufacturing of sensors on fl exible substrates; and demonstrate sensor network conductivity.

Due to limited fl exible sensor technology, some helicopter airframes have been historically passive and function without the ability to detect and assess structural damage. Continual upgrades to add more capable mission equipment to the aircraft have increased weight and stresses on the airframe with no way to monitor the lifetime effects on the structural components. There is a strong need to incorporate structural monitoring and battle damage detection capabilities into these structures.


Successful testing has been completed including: ground testing of the sensor network in the Composite Vertical Stabilizer (up to 100% of max load for landing gear, 60% of max fl ight load testing, and 90% of maximum load) and ballistic testing of sensors on composite panels at Aberdeen Proving Grounds. All panels and sensors performed as predicted.


• Advance the capability for aircraft damage detection
• Provide opportunity to integrate into the aircraft platform conditionbased maintenance system to produce structural health indicators
• Leverage the composite structures to produce lighter aircraft structures to allow for more mission equipment that can expand the soldier and aircrew warfighting capabilities
• Increase aircraft survivability
• Potentially can save lives


• Program is currently in final year of funding
• Integration, assembly, and sensor network testing started in FY09 and has been successfully completed
• Conductivity demonstration and live fire testing started in FY10 and continues on a successful path for transition to the Apache Program Manager for qualification and flight test


• AH-64 Apache Helicopter
• Unmanned Aircraft Systems
• Manned Aircraft Structures


• Return on Investment up to 17.7 to 1 with a cost benefit of $95.3M
