Titel:

Computed Tomography (CT) as a Nondestructive Test Method Used for Composite Helicopter Components

Zusammenfassung:
The first components of primary helicopter structures to be made of glass-fiber-reinforced plastics (GfRP) were the main and tail rotor blades of the Bo105 and BK117 helicopters (Bolkow system). These blades are now successfully produced in series. New developments in rotor components, e.g. the rotor-blade technology of the Bo108 and PAH2 programs, make use of very complex fiber-reinforced structures to achieve simplicity and strength. Computed tomography has been found to be an outstanding nondestructive test method for examining the internal structure of components. A CT scanner generates x-ray attenuation measurements which are used to produce computer-reconstructed images of any desired part of an object. The system images a range of flaws in composites in a number of views and planes. In the past ten years MBB has used conventional medical CT scanners to test composite materials. This paper reports on several CT investigations and their results, taking composite helicopter components as an example.
