MTS Announces AeroPro 6.1 Software for Aerospace Structural Testing

New release streamlines test setup and enhances post-test data sharing and analysis

Eden Prairie, Minn. – February 12, 2009 – MTS Systems Corporation (NASDAQ: MTSC) today announced AeroPro™ 6.1 software, the latest version of its proven control and data acquisition software for aerospace structural testing. AeroPro 6.1 builds on the powerful test-acceleration capabilities of version 6.0 with a host of new features designed to help aerospace test labs improve the speed, efficiency and safety of aerospace structural testing.

“Test labs are being pushed to perform more complex cyclic and static tests faster and often with fewer test articles,” said Mike Englerth, MTS aerospace product manager. “AeroPro 6.1 software provides the capabilities they need to streamline the setup of complex structural tests, ensure the safety of valuable test articles, improve post-test analysis and adapt quickly to changing demands.”

New AeroPro 6.1 software features a number of new utilities for accelerating structural test setup, including signal-based command via look-up table, a wizard for simplifying and automating Active Load Abort system setup, and command based on an external signal. Also new in version 6.1are capabilities for enhancing post-test efficiency and flexibility: channel parameters can now be stored with acquired data during testing, and then modified post-test to allow for data recalculation; and improved export utilities mean more efficient results sharing. Additionally, new AeroPro 6.1 software fully leverages the latest in Microsoft® software innovation with enhanced multithreading capabilities and Windows® Vista operating system compatibility.

Version 6.1 carries forward all the defining capabilities that make AeroPro software the industry’s premiere tool for aerospace structural test management, including:

Tightly-Integrated Control & Data Acquisition (DAC) – AeroPro software is the only solution capable of integrating the operation and analysis of up to 360 control channels and 10,000 data acquisition channels into a single, unified interface, eliminating the need to support separate software applications for each testing task.

Test-Accelerating Control Loop Optimization – AeroPro software features a powerful arsenal of test accelerating optimization tools, including C3 Performance and Profile Segment Optimization (PSO).

• Developed through close collaboration with NRC Canada, C3 Performance is a cross-coupling compensation utility that can dramatically accelerate complex structural tests and improve accuracy without introducing additional strains on test articles.

• Profile Segment Optimization (PSO) optimizes flight - or profile - segment times to ensure the fastest possible test execution. This is accomplished by monitoring errors between command and feedback during transitions and adjusting transition times as needed to improve the next play out of the same profile.

• Version 6.1 also features powerful Calculations in the Loop functionality, which enables advanced users to introduce sophisticated calculations into the control loop and run them at the system update rate, dramatically expanding their ability to address the most complex structural test scenarios.

Broad MTS Controller Compatibility – AeroPro software runs on several models of the new FlexTest controller family. The FlexTest family is based on a modular architecture that features uniquely field-upgradeable processors, allowing users to meet future test requirements and easily accommodate lab expansions and updates. AeroPro 6.1 software continues to support legacy Aero ST and Aero-90 control systems.

Extensive Data Acquisition Functionality – AeroPro software supports an array of leading data acquisition hardware, such as HBM and VXI Technology, and also offers a Digital Data Interface (DDI) for integrating digital input from vehicle bus or onboard monitoring sources directly into the data acquisition stream.

Streamlined Test Setup & Data Sharing – AeroPro software facilitates streamlined test setup and execution. A variety of wizards enable test engineers to easily import existing test profiles, load conditions, calculated channel configurations and historical calibration information. A database of constants greatly simplifies the development, inputting and editing of advanced equations, and custom waveform generation capabilities allow users to refine tests to meet the most exacting requirements. Test results gleaned with AeroPro 6.1 software can be easily exported into spreadsheets, tab delimited files or XML.

MTS will demonstrate the full capabilities of new AeroPro 6.1 software at Stand D134 during Aerospace Testing ’09 Munich, Germany, April 21-23.
