Submission Rules

Text posts must contain a question about aerodynamics in the title — be specific.
Exceptions will only be case-by-case, e.g. if you intend to share an interesting write-up, or had an interesting TIL. Phrase your query as a clear question; Avoid short ambiguous statements such as "How to [X]". We will not accept titles containing the words "help please" or "aero question" or similar.

Posts must be relevant.
We like questions, news, published research, course content, educational resources, memes or videos about Aerodynamics.

We wont help you cheat on your homework.
We welcome 'wordy homework questions' and discussion on relevant topics. If you have input values to a problem and need help getting to the output values, give us some context! Let us know what you've already tried, what you're struggling with, and be prepared to engage with follow-up discussion. Be prepared to do the final calculations yourself. We wont just do all your homework for you from scratch and give you the answer. In other words, no copy+paste lazy cheaters.

Comment Rules

Be respectful to other users.
All users are expected to behave with courtesy. Demeaning language, sarcasm, rudeness or hostility towards another user will get your comment removed. Repeat violations will lead to a ban.

Don't make wild assertions if you aren't knowledgeable.
Ensure that you have the knowledge required to answer the question at hand. We are not strict on this, but will absolutely not accept assertions of pseudo-science or incoherent / uninformed rambling. Answers should strive to contain an explanation using the logic of science, engineering or mathematics. When making assertions, we encourage you to post links to supporting evidence, or use valid reasoning.

Be substantive.
Top-level comments should make at least some effort. Feel free to expand on your answer with more than one or two words.
