Overview
Background & policy context:
There are several challenges for the development of future high-pressure turbines of aircraft engines: Besides a high efficiency, low weight and costs, there are increasing requirements concerning service life and reliability. The development cycles have to be short and steady, and the after-sales support should be effective and cost-efficient.
Objectives:
The objective of the RobusTurb project is to develop several technological aspects which all contribute to the overall target of a robust high-pressure turbine. Therefore, the project focuses on connecting various concepts, forecasts and new alloys and materials.
Methodology:
To capture the multidisciplinary nature of potential challenges, the RobusTurb project is divided into 9 subprojects:
- Subproject 1- Improved aero-thermodynamic concepts
- Subproject 2- “cyclone” cooling concept and model of the turbulent Prandtl number
- Subproject 3- non-stationary impingement cooling concepts
- Subproject 4- energy consumption: Overall performance of the high-pressure turbine
- Subproject 5- draft: transonic turbine with 1.5 levels.
- Subproject 6- multidisciplinary optimization
- Subproject 7- Improved modelling of the contact points
- Subproject 8- Improved assessment of damages
- Subproject 9- Evaluation of the “Allvac 718Plus” material
