Learning outcomes

The main objective is to give to students the basic know-how necessary to properly design experimental tests to be conducted in a test rig, to acquire data, and to analyze them in order to obtain the required information on the turbine or engine under study.

Course contents

Introduction to the use of an Engine Test Room
The architecture of a engine test room: the systems present in the test room and description of their behaviour.
Signal acquisition: Hints on signal sampling and the aliasing phenomenon.

Performing experimental tests
Visit of the engine room test and description of the test room control systems. Experimental tests with data acquisition will be carried out.

Data processing
After the acquisitions performed in the test room, Matlab language procedures will be developed to process the signals and extract information in order to deeply understand the behaviour of the tested systems.
The tests and the analysis of the relevant experimental data will be performed on the following systems:
- a turbogas for aeronautical propulsion to obtain its thermodynamic cycle on the plane (T, s) and the determination of its performance;
- a compression ignition engine to study the combustion and the determination of the heat release;
- a spark ignition engine for analyzing the mean and instantaneous rotational speed and the detonation phenomenon.

Teaching methods

The course is based on theoretical lectures on theory of measurements, tests carried out in the lab, and data analysis.

The material - both in terms of explanation of the topics covered, codes developed in the classroom and the relative data - will be made available on the IOL platform.

Assessment methods

At the oral examination the student must present a report of maximum 25 pages in which he summarizes the results obtained in the analysis of the three experimental tests that were analyzed during the laboratory activities.

The assessment of learning is valuated in an oral exam lasting about 30 minutes in which the teacher asks the student to explain what was reported in some parts of the report. The student must be able to explain the methodology used to analyze the data and to obtain the results reported in the report.

Teaching tools

Exercises will be carried out in the computer room, using Matlab-Simulink.
