SAN FRANCISCO—Composites continue making inroads on airframe and engine components, but for MROs in the composite structure repair business, managing the exotic carbon fiber materials and adhesives can be a logistical nightmare.
The proliferation of mobile devices and software that enables increasingly more complex data distribution and handling could lead to the most significant evolution in maintenance documents management since the transition from paper to electronic formats.
Blowing sand in the Middle East and high levels of airborne particulate matter from industrial pollution in Asia are parts of the impetus behind a new generation of thermal barrier coatings (TBC) designed to better protect engine components and withstand corrosive elements.
TBC corrosion is becoming a growing issue, specifically attributable to the build-up of calcium magnesium aluminosilicates (CMAS).
As more nacelles are made of composites, their repair market is becoming quite diverse.
“Fleet transitions are adding complexity, failure modes vary as aircraft age, and operators are customizing work scopes to fit their needs,” says Meredith Siegfried, CEO of Nordam, a major nacelle OEM and repair specialist.
Siegfried says most of today's nacelle work stems from mature aircraft, which generally employ comparable technologies and materials, so today's primary focus is on doing the work faster and cheaper.
An analysis of Airbus' and Boeing's delivery data from Aviation Week Intelligence Network's Fleet database reveals that both Airbus and Boeing tend to deliver a majority of their aircraft during the second half of each month....More
"These finding have implications for planetary protection policies for future landed spacecraft," according to the Nature Geoscience report. "Cl-bearing brines are very corrosive and this may have implications on spacecraft design and surface operations."...More
