Welcome to the On-line resources for Aerodynamic Design of Aircraft with Computational Software. The guiding principle for the book is learning by computing with ready-made software. This learning-by-doing approach to teaching aerodynamic design is accomplished by working with exercises, tutorials, and extended projects and using the computational tools under guidance. Experience gained in carrying out these exercises will help student when completing a tern project or a capstone design course or writing a senior-year, masters, or PhD thesis. The hands-on assignments are presented not in the book itself, but on this website. Useful public-domain software, which has been used for computing many of the examples in this book, can also be found here. Downloads of software and documentation as well as links to the home and developer pages for the different packages are provided.
The Airinnova website (here) provides a Virtual Machine with all software installed and m-file or python scripts for some of the tasks. These are all arranged in a directory structure following the chapters, like the tabs for the chapter material on this page, and libraries necessary are linked already in the scripts. Don’t move them unless you are sure how those connections should be set.
Example: Optimization tasks in Ch. 1
For instance, Ch. 1 gives an overview of algorithmic design by non-linear optimization, and the scripts in
.../Ch1 opt1.m and
opt2.m are ready-to-run, by starting octave in GUI mode in a terminal window:
>octave --gui &
which lets the student browse, inspect, modify, and run the m-files interactively. The script can also be executed in a terminal by
which runs the calculation and exits. This is less convenient since any plots generated will be closed. The Ch.1 scripts need the
optim octave toolbox which is installed but must be loaded at the start of any octave session that wants to use it. This also is taken care of in the scripts given.
The next task is for the student to modify the scripts and the relevant functions (here
constr.m) to solve another performance optimization task. The “real deal” in Ch.1 is shape optimization. That requires flow simulation by CFD and such examples will have to wait until Ch.3 in connection with exposition of the VLM flow model.
In a standard course the instructor will provide a walk-through and demo to show how it all works. Then for each lecture a list of relevant tutorials, labs, self-study activities with review questions will normally also be provided by the instructor as the lecture series unfolds. The questions usually require the students to read parts of the chapters which have not been covered in detail in lecture form.
