Load Monitoring - "intelligent" aircraft wing gauges strains in case of overload

14.04.2008
At the Aerospace Testing Expo 2008 in Munich, 15 - 17 April, scientists of the Fraunhofer Institute for Structural Durability and System Reliability LBF will present a self-made mock-up of an "intelligent" wing for a future Very Light Aircraft that may be able to monitor fatigue relevant strains during operation. (Hall A1, Booth D185)

Today's aircraft are in use almost 24 hours a day. Functional reliability and operational safety are achieved by international maintenance standards for each component. In the future, sensor systems could assist the operators in monitoring, for example, aircraft wings.

"Sensors inside the wing measure cyclically-occurring structural strains. This generates load and stress data, which enable design engineers to tap the full potential of lightweight constructions in airplanes to reduce fuel consumption and noxious emissions," explains Dr. Andreas Büter, head of Lightweight Structures at the Fraunhofer LBF.

By sensory monitoring of aircraft parts, the assessment of residual fatigue life of components, for instance, after the occurrence of extreme loads, should become possible. Furthermore, time and cost-intensive maintenance cycles could be optimized.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
