Experimental Investigation of the Upstream Effect of Different Low Pressure Turbine Exit Guide Vane Designs on Rotor Blade Vibration
Autor: A. Marn, C. Schitter, Thorsten Selic, Franz Heitmeir, Florian Schönleitner
Publikováno v: Volume 7B: Structures and Dynamics.
Exit guide vanes of turbine exit casings are designed to meet aerodynamic, structural and acoustic criteria. New low pressure turbine architectures of aero engines try to optimize components weight in order to decrease the fuel consumption and reduce

On the Effect of Axial Spacing Between Rotor and Stator Onto the Blade Vibrations of a Low Pressure Turbine Stage at Engine Relevant Operating Conditions
Autor: Franz Heitmeir, Florian Schönleitner, Mathias Mayr, Andreas Marn, Thorsten Selic
Publikováno v: Volume 7B: Structures and Dynamics.
In order to achieve the ACARE targets regarding reduction of emissions, it is essential to reduce fuel consumption drastically. Reducing engine weight is supporting this target and one option to reduce weight is to reduce the overall engine length (s

Acoustic Comparison of Different Turbine Exit Guide Vane Designs Part 2: Experimental Analysis
Autor: Franz Heitmeir, Martin Hoeger, Florian Schönleitner, Thorsten Selic, Andreas Marn, Dominik Broszat, Stefan Zerobin
Publikováno v: 21st AIAA/CEAS Aeroacoustics Conference.
In this paper the sound power levels of three different designs of turbine exit guide vanes (TEGV) of turbine exit casings are compared with a standard design of an TEGV. The comparison is made with respect to the LPT for the acoustically relevant op

Modal Characterization, Strain Gauge Setup and 1-Way FSI of a Low Pressure Turbine Rotor Blading
Autor: L. Traussnig, A. Marn, Franz Heitmeir, Florian Schönleitner
Publikováno v: Volume 7B: Structures and Dynamics.
New designs of low pressure turbines show optimized geometries of stator and rotor blading as well as reduced axial spacing between stator and rotor due to the main target of saving weight which is directly related to the fuel consumption of the aero

Comparison of the Aerodynamics of Acoustically Designed Exit Guide Vanes and a State-of-the-Art Exit Guide Vane
Autor: Franz Heitmeir, Dominik Broszat, Andreas Marn, Thorsten Selic, Florian Schönleitner
Publikováno v: Journal of Turbomachinery. 137
Within previous EU projects, possible modifications to the engine architecture have been investigated, which would allow for an optimized aerodynamic or acoustic design of the exit guide vanes (EGVs) of the turbine exit casing (TEC). However, the eng
