Python for Mechanical and Aerospace Engineering

by Alex Kenan

Overview

The traditional computer science courses for engineering focus on the fundamentals of programming without demonstrating the wide array of practical applications for fields outside of computer science. Thus, the mindset of "Java/Python is for computer science people or programmers, and MATLAB is for engineering" develops. MATLAB tends to dominate the engineering space because it is viewed as a batteries-included software kit that is focused on functional programming. Everything in MATLAB is some sort of array, and it lends itself to engineering integration with its toolkits like Simulink and other add-ins. The downside of MATLAB is that it is proprietary software, the license is expensive to purchase, and it is more limited than Python for doing tasks besides calculating or data capturing.

This book is about the Python programming language. Specifically, it is about Python in the context of mechanical and aerospace engineering. Did you know that Python can be used to model a satellite orbiting the Earth? This book assumes a college junior level of mechanical/aerospace engineering understanding. It will use examples like

• Thrust available and thrust required for an aircraft


• Dynamic pressure and how it changes with altitude and velocity


• Plotting different airfoils


• Orbital mechanics and orbital parameters


• Mechanical properties of different aluminum alloys

to show the reader how Python is better than MATLAB for anything that does not require Simulink. Don't be scared if you don't understand all of those topics; they are just being used to provide concrete examples for how Python can be used for engineering.

In total, there are 10 chapters:

1. Intro chapter on how to download Python via Anaconda distribution and getting started with Python syntax


2. A very small problem and solution to demonstrate a basic Python program


3. Graphing thrust required and thrust available for an A321 at three different altitudes with matplotlib


4. Graphing dynamic pressure as a function of time for a rocket launch with Matplotlib


5. Getting and plotting airfoil coordinates with Requests and Matplotlib


6. Modeling a satellite's orbit around Earth with PyAstronomy and Matplotlib


7. Introduction to web scraping (Requests and BeautifulSoup4) and exporting data to Excel (Openpyxl)


8. Modeling camera shutter effect on an aircraft's propeller with Tkinter and Numpy


9. Creating a GUI to convert units with Tkinter and Pint


10. Making pdf reports of Python code with Pweave

You can find the completed programs and a very helpful 595 page NSA Python tutorial at the book's GitHub page at https://www.github.com/alexkenan/pymae.

About the Author

Alex Kenan is a Senior Analyst at Delta Air Lines in the SkyMiles loyalty program, focusing on data analysis and program strategy. He uses Python, SAS software suite, and Oracle Hyperion to build models of future customer behavior, creates consumer insight from past customer behavior, and performs ad-hoc analyses for frequent flyer population impact. He provides instruction to new hires on data analysis in SAS software suite, Oracle Hyperion, Microsoft Access, and Python. He also uses Python to catch and prevent fraud in the SkyMiles program by identifying and blocking fraudulent redemptions and identifying hacked customer accounts.

Alex previously worked as a Propulsion Engineer for Delta TechOps where he oversaw a jet engine portfolio of nearly 200 Rolls-Royce engines, and nearly 900 CFM56-5A, CFM56-5B, and CFM56-7B engines before that. He was responsible for the overall engine reliability for in-flight shutdown rate, unscheduled engine removal rate, and delays attributed to engine issues. He used Python to correlate engine component failure to FADEC faults which improved engine component troubleshooting and reduced engine component repair and overhaul costs.

Alex holds a Bachelor of Science degree in Aerospace Engineering from the University of Virginia and a Master of Business Administration from Emory University’s Goizueta School of Business.
