Project Dream - The Institute of Aircraft Propulsion Systems of Stuttgart University

USTUTT

Universität Stuttgart was founded 1829. The University has more than 140 institutes, distributed over 10 faculties, employs almost 5500 people and caters for more than 20000 students – among them more than 3000 young women and men from all over the world. Since 1911 Universität Stuttgart has an academic research path in aerospace engineering.

The two institutes participating in the EU-Program DREAM are the Institute of Aerospace Thermodynamics (ITLR) and the Institute of Propulsion (ILA). Both institutes are part of the faculty of aerospace engineering and geodesy.

ITLR

Two professors are associated to the Institute of Aerospace Thermodynamics (ITLR). The institute has about 35 scientists and about 15 non-scientific employees (technicians, designer etc) and several testing equipment. Research topics of the institute are: heat transfer, aerothermodynamics, droplet dynamics, supersonic combustion and shock tube research.

Researches on convective Heat Transfer are one of the largest topics at the ITLR and are fundamental to develop and optimize cooling methods of gas turbine components such as turbine vanes or blades (internal cooling), combustor liner and turbine casing (external cooling). At the ITLR the investigation of the complex behaviour of the flow in these cases is done numerically and experimentally in order to obtain a high heat transfer rate and decrease the pressure drop. This is essential to increase the efficiency of modern gas turbines.

ILA

The Institute of Aircraft Propulsion Systems of Stuttgart University targets it‘s research on the numerical description and simulation of total system behaviour. In consequence all detailed aerodynamic and thermodynamic investigations at the institute shall be directly related to the complex technical system under research.

Besides purely technical research the Institute of Aircraft Propulsion Systems does research on important cross functional issues of the Turbo Machinery Industry, e.g. technical-economical issues with regards to development, design, production, maintenance and utilisation of turbo machines.

USTUTT AND DREAM

The part of the Institute of Aerospace Aerodynamics (ITLR) of Universität Stuttgart will be the measurement and the modelling of pressure losses and impingement heat transfer characteristics in the ACC close loop system developed and produced by MTU for the GP 7200 Engine.

Within DREAM the consolidated findings will be essential for the conception of the new ACC system developed by MTU in cooperation with MAGNA. The outcome of the DREAM project will enable the ITLR to consolidate and to extend its expert knowledge in the method of impingement cooling.

The Institute of Aircraft Propulsion Systems (ILA) of Univeristät Stuttgart will be part of the TERA2020 activities in DREAM. These activities are a consequent extension of ILA activities in VITAL and NEWAC. As in the other activities ILA will concentrate on the cost estimation within TERA 2020 and will work together with the other partners in the integration of the needed TERA2020 extensions.

ILA will benefit from this activity through the application of the existing method on other engine architectures. Furthermore ILA benefit from the extended verification which has to be done in DREAM also.
