no doubt the wind tunnel model of the European TILTROTOR, realized by the Rapid Prototyping Department of CRP Technology during the first months of the 2007. The wind tunnel model has been designed and projected by our italian customer Sistemi Dinamici Spa for AGUSTA WESTLAND. This project allowed, once again, to highlight the perfect union between RP technology and WINDFORM materials. Thanks to the WINDFORM materials, it was possible to complete and test the model in the wind tunnel within a very short time, with excellent results and with really high-performing mechanical and aerodynamic properties. The project related to the manufacturing of the external fairings of a wind tunnel model (1:8 scale) for the prototype of the European TILTROTOR, made by Rapid Prototyping and WINDFORM® GF material. This mock up was designed and projected by Sistemi Dinamici Spa for AGUSTA WESTLAND, for a research program, sponsored by the European Community whose aim is to develop the European TILTROTOR.

14.45-15.15 Implementation of a Particle Image Velocimetry (PIV) system in the BAE Systems 4m Low Speed Wind Tunnel

Brian Cleator, Wind Tunnel Operations Manager, BAE Systems

The presentation will describe the process followed to install and commission a fully developed PIV system in the BAE Systems 4m Low Speed wind tunnel.

15.15-15.45 RUAG Precise Propulsion and Measurement Technology for Low Speed Wind Tunnel Testing

Michel Guillaume, General Manager, RUAG Aviation

RUAG has a long tradition in developing, manufacturing and operating precise 6 component strain gauge balances. Based on this experience a second block-type balance family was developed with substantial higher stiffness and increased specific load capacities. In close cooperation with other partners RUAG plays a major role in the testing and development of the new counter rotating technology for future aircrafts. This technology in combination with space limitations inside the nacelle requires new measurement technology and substantial higher power as provided by existing propulsion systems. Based on it’s available know-how RUAG pushed the hydraulic propulsor technology to a new dimension.

Industrial solutions for in-flight & offline experimental flutter analysis

Jan Debille, Aerospace Testing Solutions Manager, LMS

Testing during first flight - where aerodynamic and aero elastic behavior predicted by simulation models, needs to be confirmed - is time consuming. This testing time can be greatly reduced using smart tools fit for industrial purposes. This presentation presents industrial solutions for experimental flutter analysis. Experimental flutter analysis needs to be able to acquire data in operational conditions, automatically perform modal analysis, make a statement on actual flutter conditions, and finally, deal with flutter prediction. An overview of prediction techniques is given. The new developments for in-flight data analysis are illustrated by wind tunnel and real-life aircraft in-flight tests.

Structural Testing

10.00-10.30 Structural & acoustical testing for efficient and safe aircrafts

Tim Fountain, Market Dev. Mrg, Aero & Defense, National Instruments

Aircraft are subject to heavy mechanical loads and often cause an undesirably high noise pollution. Therefore, structural as well as acoustic tests play a vital role when developing reliable and efficient flying objects like civil aircrafts and military fighter jets. Learn how to rapidly acquire and analyze test measurement data like force, strain, sound and vibration, using an open, scalable test and measurement platform.

11.00-11.30 The Challenge of successful structural testings

Stephan Ploegman, Aerospace Test Systems, Project Manager, Moog

11.30-12.00 In-flight structural dynamics testing of a very large aircraft: excitation and data analysis techniques

Jan Debille, Aerospace Testing Solution Manager, LMS international

Aero elasticity, the interaction between inertial, elastic and aerodynamic forces is crucial in aircraft design. As aircraft designs get optimized, aero elastic behavior becomes more complex. Along with aircraft optimization, modal identification methods used during flutter testing have advanced to assure correct parameters identification. Tuning an aero-elastic model requires very accurate in-flight frequency and damping estimations. This presentation discusses excitation and highly accurate data analysis techniques for in-flight testing. Main concepts are illustrated using data from a very large four-engine aircraft, instrumented with over 100 accelerometers during the test flight.

12.00-12.30 Test Article Safety

Arlin Nelson, Applications Engineer, MTS Systems Corporation

Today’s aerospace test program schedules are tremendously aggressive and often budget-constrained to a point where time and money pressures can increase risk of test article damage. Yet, protecting test articles from catastrophic damage created by accidental loads or unexpected test shutdown is paramount in meeting test program schedules and budgets. This presentation outlines the many options for enhancing test article safety; including mechanical attachments and load limiters, abort manifolds and the safety features that can be built into the controller, DAC and hydraulic systems. Come learn how to evaluate the options and balance test setup costs with test article safety considerations.
