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: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
