Measurement, Engine & Airframe

Module name (EN):
Name of module in study programme. It should be precise and clear.
Measurement, Engine & Airframe
Degree programme:
Study Programme with validity of corresponding study regulations containing this module.
Aviation Business (Basic), Bachelor, ASPO 01.10.2018
Module code: ABBG14
The exam administration creates a SAP-Submodule-No for every exam type in every module. The SAP-Submodule-No is equal for the same module in different study programs.
Hours per semester week / Teaching method:
The count of hours per week is a combination of lecture (V for German Vorlesung), exercise (U for Übung), practice (P) oder project (PA). For example a course of the form 2V+2U has 2 hours of lecture and 2 hours of exercise per week.
4V (4 hours per week)
ECTS credits:
European Credit Transfer System. Points for successful completion of a course. Each ECTS point represents a workload of 30 hours.
Semester: 2
Mandatory course: yes
Language of instruction:
Written exam (120 minutes)

[updated 01.10.2020]
Exam recurrence:
The information regarding exam recurrence is found within the exam policy of the study programme (ASPO).
Applicability / Curricular relevance:
All study programs (with year of the version of study regulations) containing the course.

ABBG14 (P410-0031) Aviation Business (Basic), Bachelor, ASPO 01.10.2015 , semester 4, mandatory course
ABBG14 (P410-0031) Aviation Business (Basic), Bachelor, ASPO 01.10.2018 , semester 2, mandatory course
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
60 class hours (= 45 clock hours) over a 15-week period.
The total student study time is 150 hours (equivalent to 5 ECTS credits).
There are therefore 105 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):

Learning outcomes:
After successfully completing this part of the module, students will be able to explain the physical principles on which measurements are based. They will be able to describe the technical implementation of these physical relationships of the most important measurement methods in aviation. Students will also be able to describe how a measurement result is obtained and explain possible measurement errors. To do this, students will first learn to classify the basic terms of measurement technology and develop an understanding of the actual measurement process. After this, students will be introduced to the problem of measurement errors (including possible causes) and estimating errors of indirectly measured quantities using the theory of Gaussian error propagation (e.g. determining density using the ideal gas equation, determining velocity using the Bernoulli equation, etc.). Furthermore, students will learn to evaluate measuring equipment with the help of statistical methods. Based on the assumption of a normally distributed population, mean value and standard deviation serve this purpose. Subsequently, students will learn about possible conversion principles and the measuring devices derived from them for physical quantities relevant in aviation and aero-/thermodynamics and will thus, be able to evaluate the respective conversion principles with regard to their applicability and significance. The latter includes the technical correlations and application of these in case studies (e.g. calculating a temperature increase from the measured thermoelectric voltage).
After successfully completing this part of the module, students will be able to describe and classify the different conventional propulsion systems used in aircrafts (especially commercial aircrafts). Furthermore, they will be able to explain the function and mode of operation of turbojet engines and their components. In addition, they will be able to characterize individual engines by means of various key figures (unit mass, specific thrust, specific fuel consumption, propulsion efficiency, etc.). They will be familiar with the physical principles and will be able to explain them with the help of thermodynamic relationships (e.g. ideal gas equation, conservation laws, cyclic processes). Based on this knowledge, students will be able to formulate the requirements for aircraft engines, e.g. with regard to pollutant emissions, fuel consumption and noise development.  Finally, students will be able to illustrate which future technologies can be used to meet these requirements.
After successfully completing this part of the module, students will be familiar with the main design groups of an aircraft and will be able to describe them. They will also be able to differentiate between construction methods, types of construction, construction principles and be able to give examples. On the basis of simple examples, students will be able to identify geometric and material parameters that influence the level of stress in the individual construction groups of the airframe. Using the airframe structure of the A300B2 and B4, students will apply what they have learned and deepen their knowledge in a case study on the A318/A319/A320/A321.
