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

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.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
