10.30-11.00 Compressor Testing at MTU Aero Engines Part 1 Testbed / Instrumentation / Data Acquisition

Ingolf Krenz, Manager Rig Testing, MTU Aero Engines

MTU Aero Engines has two testbeds for compressor testing. It is possible to test low, intermediate or high pressure compressors for both aero / performance and me-chanical analysis. For the different types of compressors special features are implemented, e.g. heated inlet for high pressure compressors to simulate engine like conditions or separate core and bypass exhaust pipes and throttles for low pressure compressors. When running modern multi stage compressors with variable guide vanes, control systems are used for safe de- and acceleration. Instrumentation, data acquisition and online analysis are designed for quick health and safety monitoring and detailed analysis of aero, performance and mechanical parameters.

11.00-11.30 Compressor Rig Testing at MTU Aero Engines - Part 2: Model-based data analysis

Wolfgang Horn, Performance Engineer, MTU Aero Engine

A new procedure has been adopted for test monitoring and data analysis at MTU Munich’s compressor rig test facility. It is based on a thermodynamic model of the compressor rig and the flowpath through the test facility. The approach allows an online comparison with expected values, an advanced measurement check procedure and a direct feedback to test and design engineers. The presentation will show the concept of the analysis tool and outline the data analysis methodology at MTU from data acquisition to test results.

11.30-12.00 Maximizing Accuracies Through a Distributed Measurement Approach

Jon Semancik, Director, Business Development, VTI Instruments Corporation

Distributed data acquisition systems offer improved measurement accuracy and easy setup when compared to centralized systems, however, their design must take into account signal conditioning, self-calibration, excitation, and noise rejection to achieve the most accurate and reliable measurement results. While a centralized approach provides convenient control room access to the signal conditioning and instrumentation, the long cable lengths can cause unintentional measurement error by introducing electrical noise, calibration uncertainty, bridge excitation uncertainty, and cable impedance. To improve measurement accuracy, test engineers use a distributed measurement philosophy by placing the instrumentation near the test article.

12.00-12.30 Centralized and decentralized amplifier systems for high channel count applications in the aerospace industry

Marc Zürn, Hottinger Baldwin Messtechnik GmbH

In applications of the experimental structural and stress analysis strain gauges are used to measure strain in small to very big mechanical structures. For a structural analysis of an aircraft body thousands of strain gauges are necessary. The challenge in these applications for the data acquisition system is to readout and measure all data synchronized. Further more it is critical to minimize costs and negative effects caused by complex cabling. A combination of centralized and decentralized synchronized Data acquisition to generate the data has many advantages. The insert and advantages of such a hybrid data acquisition system and the software user interface will be presented.

10.45-11.15 Nondestructive inspection of composites with infrared thermnography

Carosena Meola, Dr, Universit

In 2010 the German Aerospace Center (DLR) will conduct the second experiment of its hypersonic Sharp Edge Flight Experiment Program SHEFEX-2. The mission will investigate new shapes for launcher or re-entry vehicles with faceted surfaces. A key re-entry technology to demonstrate is hypersonic flight control using steerable canards relying on an accurate hybrid navigation system with multiple sensors. This talk presents the methodology of the hardware-in-the-loop tests of the hybrid navigation system using a dSPACE HIL system. These tests subject the flight hardware to simulated flight and laboratory conditions in three phases to debug the system and prove robustness.
