F O C U S A V I AT I O N 2PTS 3PTS 4PTS 5PTS AUTOMOTIVE KNOW-HOW FOR AVIATION MEASUREMENT SOLUTIONS When OEMs and the authorities began work on the development of a new measuring solution that addresses the specific technical challenges of certifying jet engines, AVL was contacted. “In 2011, our US emissions expert Bill Silvis and Manfred Linke, Sales Manager, made it possible to assist in the development of a new measuring procedure. We soon realized that the technical requirements could be met very efficiently based on our product portfolio, and by drawing on the technology know-how of application experts from the global AVL team,” Dieter Florian, Global Business Segment Manager Particle Measurement, told FOCUS. Beyond developing the equipment for the aviation industry, AVL also supported the setup of EMPA’s European reference system (Eidgenössische Material Prüfanstalt, Swiss Federal Laboratories for Materials Science & Technology) at the airport in Zürich by supplying application knowledge. After that, AVL converted the reference system into an industrialized sampling system: “The AVL Particle Measurement System Aviation (PMS) consists of the newly developed AVL Particle Sampling System Aviation including the Control Software and the specifically adapted standard products AVL Micro Soot Sensor Aviation (MSS) and the AVL Particle Counter Aviation (APC),” Dieter Florian explained. Thanks to AVL’s decade-long experience in the field of particle measurement systems, the customer requirements were implemented in the best possible way. “The all-in-one package provides customers with an easy and efficient solution for the jet engine certification. Moreover, the measurement system offers customers a very high measurement data quality, which is of major importance because a certification run may cost several hundreds of thousands of US dollars. In addition, the high measurement repeatability, especially for the determination of nm particles in turbine test facilities, poses a huge challenge for a system length of 35(!) meters”, Roman Davok, AVL Product Manager Particle Measurement, explained. AVIATION LEGISLATION – AN IMPULSE FOR UPDATES IN THE AUTOMOTIVE INDUSTRY? This new particle emission regulation for the aviation industry relies on the latest technology trends. Dynamic soot measurement, for example, has for the first time found its way into an emission legislation, the PN quantity has for the first time become relevant in an US emission standard, and PN measurements for particles < 23 nm could soon become relevant for discussions in the automotive legislation. “In the meantime, EU research projects are being run in order to better understand the mechanisms of particle formation for modern diesel and gasoline engines” Dieter Florian concluded. So, AVL has successfully contributed its technology expertise and product innovations to another emission application. Thus the allin one solution has great potential of becoming a future standard for the aviation industry. < System Control Software Aviation 3rd Device Gas Transfer System – GTS raw PTS ...
