Fraunhofer ILT wins Aviation Week 2012 Innovation Challenge for Additive Manufacturing of BLISKs

29.03.2012
The American magazine Aviation Week awards excellent solutions for the aerospace and defense (A&D) industry annually.
Sought-after are new developments, e.g., for sinking production costs and improving integration of innovative technologies. The team from the Fraunhofer Institute for Laser Technology ILT has won the 2012 Innovation Challenge in the category “Power and Propulsion” for its additive manufacturing process of BLISKs. Representing the entire team, Dr. Ingomar Kelbassa and Johannes Witzel received the award in Washington, D.C. on March 7, 2012.

Turbomachines form the heart of power plants and airplanes. As the need for energy and mobility grows, so too increases the demand for turbomachines as providers of energy. What is currently at stake is designing them in such a way that they produce more energy and less CO2 while using less fuel. Researchers at the Fraunhofer Institute for Production Technology IPT and the Fraunhofer Institute for Laser Technology ILT have made it their goal of implementing processes for the manufacture and maintenance of energy-efficient turbomachines. Together with the Fraunhofer Society and the German Federal State of North-Rhine Westphalia, they have called into life the Aachen Fraunhofer Cluster for Innovation “Integrative Production Technology for Energy-Efficient Turbomachines” with a total volume of 10.25 million Euros. Also part of the project are 16 industrial enterprises, among others global players such as MAN Diesel & Turbo, Siemens PG, Rolls-Royce Deutschland and MTU Aero Engines.

Preserving Resources and the Environment Intelligently

BLISKs are important components for aircraft engine and turbine construction, consisting of disks with integrated compressor blades. Currently BLISKs are produced with conventional manufacturing processes, e.g. five-axis milling, creating a great loss of material and use of energy and time, and causing very high production costs. Within the Fraunhofer Cluster for Innovation “TurPro” – in cooperation with Rolls-Royce Deutschland Ltd & Co KG as well as in partnership with the Fraunhofer IPT – the Fraunhofer ILT has developed a laser-based process that preserves resources during manufacture and maintenance of BLISKs.

In this process, a powder feed nozzle applies a layer of nickel or titanium-based alloy exactly where a blade should be formed on the disc with the highest precision. Then, the laser beam melts the powder and joins it with the underlying material. This way, a compressor blade can be built layer by layer. This additive manufacturing method, Laser Material Deposition LMD, is also suitable for maintaining components. Using the innovative manufacturing technology, the Aachen researchers have been able to save materials by up to 60 percent as compared to conventional processes and to shorten the overall manufacturing time by around 30 percent, all of which slashes the production costs of BLISKS significantly.

Im Focus: Biotechnology: Triggered by light, a novel way to switch on an enzyme

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".

Im Focus: New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Im Focus: I-call - When microimplants communicate with each other / Innovation driver digitization - "Smart Health“

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.

When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...

Im Focus: When predictions of theoretical chemists become reality

Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.

Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...

Im Focus: Rolling into the deep

Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
