Aeroelastic and Aeroacousic Experiments – PHARE 2

A comprehensive approach is envisaged, fundamentally based on immense synchronized instrumentation. The ground-breaking difference towards conventional research approaches is that the inseparability of the phenomena leading to instability is accepted and it is intended to understand and quantify them in the coupled system. Additionally to the characterization of the instability phenomena, the planned experimental setup will also allow a detailed assessment of the global performance and the emitted noise of the test case, which increases the value for computational method validation. The proposed concept combines complementary measurement systems and enables the detection of interactive mechanisms and instability phenomena where individual systems are insufficient. Unstable aerodynamic phenomena like local flow separations and interactions between shock and tip leakage vortex or boundary layer are sensitive to external feedback mechanisms, either acoustic or structural. It is absolutely necessary to cover all physical contributions synchronously during transient experiments to clearly characterize the coupling mechanism. To achieve this goal it is intended to realize the followng instrumentation concept:

The anticipated methodology is expected to allow a characterization and quantification of the contributing effects in the stable operating range and during transient onset of instability. A comprehensive approach is envisaged, fundamentally based on immense synchronized instrumentation.

Specifically designed for such a multi-physical investigation, two high-speed test facilities have been commissioned within the EU-Framework-7 programme in 2017 at ECL and proven their suitability for transient experiments.

The core investigation is planned to be conducted on PHARE-2, a 3MW fan test rig with advanced aerodynamic, acoustic and structure-dynamic instrumentation. Aerodynamic, aeroelastic and aeroacoustic investigations including Laser-optical methods will be led by LMFA, complemented by the Von Karman Institute who will participate with advanced unsteady instrumentations, accuracy studies and analysis techniques.

Structure-Dynamic Experiments – PHARE 1

To derive isolated mechanical characteristics - particularly exact eigenfrequencies and modal damping - the fan will be analysed on the high speed vacuum facility PHARE-1. Here, the individual blades will be equipped with piezo actuators to excite structural modes. Via strain gauges, the response of the blades can be determined.

This rig is dedicated to experimental studies on full scale rotating industrial Fans or Compressor bladed disks at their operating conditions and focusing on the structural dynamics behaviour. Basically the fluid-structure coupling interaction is suppressed as the experiments are performed in vacuum. Also, these conditions allow to drive the specimen using a relatively small amount of power. While aeroelastic excitations are removed, a very versatile piezoelectric excitation system is used for generating vibrations needed for modal testing. The influence on blade response of experiment parameters – namely rotating speed, excitation spectrum, excitation strength and spatial distribution over the fan or compressor - can then be precisely investigated. This research effort is related to several scientific topics: general vibration characterisation of full set of rotating blades involving effects such as stress stiffening, Coriolis, large strains or large displacements vibrations, structural and friction damping. These latter are crucial issues for flutter instability studies where fluid interaction is taken into account after by numerical CFD. The nonlinear analysis of vibrating behaviours induced by friction or contact between parts of the assembly is also a major challenging and need accurate and extensive experimental data required for correlation with solid mechanic numerical computations.

One of the major goals of the facility PHARE-1 is to provide such complete and reliable database of experimental results in the field of vibrating and rotating nonlinear structures. The aim is to follow a scientific approach using numerical models compared to experimental data in order to obtain a deeper understanding of physical phenomena involved in such full scale industrial complex structures.
The rig can also serve to demonstrate the efficiency of innovative solutions for reducing vibration levels on the studied test pieces or to evaluate different means of monitoring and measurement technics.
Figure xx depicts a cross sectional view of the test rig. The idea of this test rig is to use an electric motor (650 kW) able to accelerate inertia of full scale test specimen representative of next fan and compressor generations. This is made possible by operating the specimen inside a vacuum chamber extracted by a double stage rotating 630m³/h vane vacuum pump. The driving power is transmitted from the motor up to 8000rpm to the rotating part inside the chamber by means of a rotating seal. The specimen under study is mounted on a supporting rotor whose bearings are lubricated inside the vacuum chamber, oil being returned back from vacuum to the hydraulic unit at ambient pressure.
A telemetry system has been adapted on the driving shaft in order to carry out measurements in the rotating frame and for the alimentation of the piezoelectric actuators. This 44 dynamic strain measurement channels telemetry has the capacity of measuring the 16 blades fan of the CATANA project with very good accuracy and completeness.

Project Organization / Partners

Responsibility
The partners of Project CATANA are the laboratories LMFA and LTDS of Ecole Centrale de Lyon as well as the Von Karman Institute for Fluid Dynamics in Brussels. The project coordination and all aerodynamic and aeroelastic experiments on the fan test facility PHARE-2 / ECL-B3 are conducted by the Turbomachinery Group of LMFA (Coordinators / PIs: Xavier Ottavy and Christoph Brandstetter).

ECL LMFA - Laboratoire de Mécanique des Fluides et d'Acoustique UMR CNRS 5509
Ecole Centrale de Lyon (ECL) is one of the leading French public engineering schools which delivers the Engineer Degree of the French Ministry of Education and Research. Two laboratories of ECL participate to Project CATANA:
LMFA develops fundamental and applied research in the fields of transport (aeronautics, space, land and environmental impact), internal aerodynamics, polyphasic flows, urban pollution, aerodynamics and aeroacoustics and turbomachines.
ECL LTDS - Laboratoire de Tribologie et Dynamique des Systèmes UMR CNRS 5513
The LTDS is a multidisciplinary laboratory that conducts research in tribology, mechanics of solids and structures, chemistry and physics of materials, dynamics of systems. Measurements of structural damping of the composite blades are conducted at the vacuum test facility PHARE-1 of LTDS (Resp. Claude Gibert)
VKI - The Von Karman Institute for Fluid Dynamics
Advanced Probe measurements will be performed by the Von Karman Institute for Fluid Dynamics (VKI), founded in 1956, which is an international non-profit organization for post graduate education and research (Resp. Fabrizio Fontaneto).
In the frame of CATANA, VKI will be in charge of delivering an as-complete-as-possible characterization of turbulence, both upstream and downstream the test section. At such extent, VKI will design, machine and operate up to 4 multi-sensor hot wire probes.
Furthermore, VKI will contribute to CATANA with its last developments in terms of uncertainty analysis.
