[61] Aspects of Aircraft Design and Control, Project 7

lecture 7

lecture 7 (aircraft trim) v1.1

project 7

project 7 (aircraft trim) v1.0

This lecture features guest lecturer Hamassala David Dicko who also shares authorship for the lecture source files.

It must be noted that several data in the project appendix, such as the wing root dimensions, are wrong by a factor of more than two. We found this out too late in the project set-up process to be able to correct them (this will be done for the next edition). The overall meaning and solving process in the project are not affected.

This was quite an outstanding lecture, and a rather modest project. A set of remarks accompanies this release on my blog.

Media used in this release:

  • A vast number of photos by the generous Vincent Edlinger (on Flickr, on Airliners.net)
  • 742 sideview drawing from lost source, would likely make for a good PD addition to the Wikimedia Commons
  • 3-axis streamlined ULM photos CC-0 by Olivier Cleynen
  • Cessna 172 cockpit CC by-sa Wikimedia contributor Markus Sümnick
  • 777 cockpit photo CC by Flickr user wbaiv

Many drawings were created for the purpose of this lecture but I don’t see any being published on the Wikimedia Commons (they only make sense within the context of a course).

[60] Aspects of Aircraft Design and Control, Project 6

lecture 6

lecture 6 (propulsion) v1.1

project 6

project 6 (turbofan design) v1.0

A rather conformal and straightforward lecture and project. A set of remarks accompanies this release on my blog.

Other people’s work used in these slides:

Media built for this lecture, that will be released later on this year:

  • Diagram used for derivation of the Steady Flow Energy Equation (recycled from my course on engineering thermodynamics);
  • All turbojet/turboprop/turbofan diagrams;
  • Diagram showing the effect of a duct on a free flow (about which I am particularly happy).

[59] Aspects of Aircraft Design and Control, Project 5

lecture 5

lecture 5 (scale and testing) v1.1

project 5

project 5 (wind tunnel design) v1.0

Quite a hefty lecture, that will need some clean-up next year. An enormous amount of material was created for these slides.

A set of remarks accompanies this release on my blog.

Public Domain media scanned/reworked from books and contributed back:

Media built for this lecture and released on the Wikimedia Commons:

Media built for this lecture, not yet released:

  • A320 wing profile (will be a nice one)
  • Reynolds-number effects on flow attachment figure
  • Pressure variation in tubes figures (will require work on Bernouilli eq. page to help anywhere)
  • A few pictures, mostly of a wind tunnel, by myself.

The beutiful 1904 drawings by Ludwig Prandtl are not published on the Commons, because although they are public domain in the USA (published before 1923) they are not in Germany (Prandtl died in 1953). +70 years brings us to August 2023!

[58] Aspects of Aircraft Design and Control, Project 4

lecture 4

lecture 4 (cruise performance) v1.1

project 4

project 4 (the market for winglets) v1.0

The shortest and simplest lecture in the whole series, and quite a successful one as well. A set of comments accompanies this release on my blog.

Media used in these documents:

Documents I created that will be published on the Commons later this year:

  • Payload-range diagram build-up
  • 345/346 Payload-range, if I find time to re-draw it from Doganis 2002.

[57] Aspects of Aircraft Design and Control, Project 3

lecture 3

lecture 3 (wing geometry) v1.1

project 3

project 3 (wing loads) v1.0

A very rich lecture and an interesting, if rather unsuccessful, project. See my commentary about this project on my blog.

Many improvements, indeed far too many to list here, were brought to the slides since they were first used in class (v1.0).

Media used in these documents:

The following photos would be in the slides if they were free... I tried to purchase these shots to put them on Wikipedia but could not get in touch with the photographers. Any help getting in contact with these people would be very appreciated.

Documents I created that I then published on the Commons:

Documents I created that will be published on the Commons later this year:

  • Expected and real lift distributions figures
  • Visual explanation for circulation (unsure about copyright status)
  • Trailing and starting vortices behind glider
  • Induced downwash figures used in lifting line theory demo
  • All wing shape diagrams (unsure how to publish)
  • Principle of the dihedral figures

[56] Aspects of Aircraft Design and Control, Project 2

lecture 2

lecture 2 (runway performance) v1.1

project 2

project 2 (runway performance) v1.0

The slides are very nearly identical to those used in class last March (v1.0).

This project was by far the hardest of the course. A whole set of comments accompanies this release on my blog (your comments are welcome!).

Documents I created that will be published on the Commons later this year:

  • Forces applying on an aircraft (unsure whether this is needed)
  • Balanced Field Length diagram

[55] Aspects of Aircraft Design and Control, Project 1

lecture 1

lecture 1 (basic flight mechanics) v1.1

project 1

project 1 (flight domain) v1.0

The slides and projects are very nearly similar to those shown in class in March (v1.0). I made minor modifications and replaced a few proprietary photos with free ones.

[54] Aspects of Aircraft Design and Control, Introduction

introduction

introduction v1.1

An important evolution from the slides that were shown in class (v1.0). This document does a much better job of presenting the course as a whole, its objectives and limitations.

I wrote an important set of accompanying remarks on my blog regarding the course as a whole; a series of blog posts will follow, hopefully giving insights on the projects themselves, and how they went.
