Abstract

[en] During the first steps of an aircraft engine design project, it is important to rapidly answer to a tender process. For that, it is important to rapidly provide the first compressor maps. The aim of this study is to create a tool which is able to build compressor maps of a booster composed of three stages from geometry and MFT data of the individual stages.
The first part of this project presents the company where this internship was performed : Safran Aero Boosters. Then, the main different types of compressors, and more specifically the low pressure axial flow compressor are presented. Finally, a brief description of the parameters of interest are developed.
The second part of this work is a bibliographical study where four methods are exposed. These are the Map Fitting Tool method (MFT), the previous booster scaling, the -lines method and the booster map warping which relies on the relative warps method. The chosen method of this internship is the MFT one because it is judged as the more physical : its parameters rely on work coefficient and low coefficient. Furthermore, the data used later to confirm the efficiency of the tools created are based on these MFT parameters. With this in mind, a complete description of the MFT methodology is presented.
The third part of this report presents the multi-stage engine studied. Furthermore, a thorough description of the stacking methodology used to perform the construction of the compressor map of a three-stage booster is performed.
The fourth part presents the first tool created during the internship which allows to stack up three stages with the same VSV schedule at different speeds of rotation. After a brief presentation of the implemented tool, the development of an application is discussed.
The last part of this project gives a brief description of the use of VSV in a multi-stage compressor. Then, the second tool implemented is presented. This tool allows to enter up to three stages with three different VSV schedules but each at a given rotation speed.
Due to the outbreak of Covid-19 in Belgium, exceptional measures where taken within Safran Aero Boosters which forced the workers to work at home. Therefore, I could not end my last week at SAB and retrieve the data necessary to present concrete applications of the tools created.
