The available tools to detect skin to core disbonds are both difficult to use and require extensive training. Complex waveforms must often be interpreted. We are proposing a small, portable, low cost ultrasound camera for in-service inspection of honeycomb rotor blades for skin to core disbonds. The basis of our technique is a two dimensional imaging array which generates real time C-scan images of defects in materials. The key advantage of this system is the simplicity of the technique. Therefore, a non-specialized inspector can easily be trained to find small defects in these structures.

Based on the success of our Phase I SBIR, Imperium, Inc., with Boeing and Bell Helicopter, is submitting this proposal for the development of a field portable low cost ultrasound camera for the rapid, simple inspection for disbonds in helicopter rotor blades. As composites become more prevalent in programs such as the V22 or H1, the need for inspection of these structures is vital. Presently, there is no easy to use, simple device for maintenance personnel to find defects in blades, especially by non-specialists at the Fleet Readiness Centers (FRC’s). The inspection process is slow and labor intensive, taking many hours to perform the inspection with poor resolution. The Imperium device alleviates these issues. Specifically, we will design, build, test, and deliver a through transmission ultrasound camera device for internal blade defect detection which requires minimal training. The device will be used in a ‘dry’, or non-immersion mode. To use the device, the inspector will simply place the device over the area in question and begins scanning. A large area image will be formed. A 12”x12” area will be covered within one minute. The image quality generated is far superior to that of conventional A-scan systems or phased array ultrasonics.
