I'm going through one of my cyclical interests in aircraft, so I thought this would be a good place to start collecting resources related to aircraft design.
Please feel free to add more, including on more esoteric topics. My practical experience is limited almost entirely to models and the like, so I tend to hove to a few simple rules which suit low-speed designs using props.
1. Basic principles
2. Wing and airfoil selection
We have occasionally talked about self-defence weapons, with quite a few disagreements on all aspects of the subject. Part of the problem, to my mind, is that a perfect self-defence weapon has a bunch of conflicting requirements: compactness, ease of use, availability, stopping power (lethal or nonlethal) and reliability. Added to these conflicting requirements, we have a whole gamut of legal issues which limit the solution space which can be realistically explored: limitations on substances, types of weapons, their form and operation and so on.
To really game this one out, I propose that we completely throw out the rulebook and try to imagine the ultimate self-defence weapon. Again, this must be something that anyone can use, that is always available, that always works and that kills or incapacitates instantly.
Have at it gents.
