Aerospace Engineering: Aircraft Fundamentals (Udemy.com)

This is a 4.4 hour overview of how aircraft work, split into 25 lectures across eight sections: classification of airplanes, aerodynamics, jet engines, flight mechanics and performance. Lluís Foreman, an aeronautical engineer who grew up near Barcelona, teaches from slides with plenty of infographics. It's aimed at the curious, from high school to graduate level, and only asks for basic physics, which the requirements list says is not even mandatory. The aerodynamics and engine sections carry most of the weight, at 70 and 77 minutes each.

Reviewers like the bite-sized videos and clear explanations. One student with an electrical engineering background said the infographics did a lot of the work, and a fresh aeronautical graduate found it a useful primer on propulsion and aerodynamics. The complaints are about depth. A four-star reviewer asked the instructor to go deeper and said some topics feel missing, another wanted a V-n diagram, and a three-star review reports a few spoken mistakes that need revision. The rating split backs this up: about 2,600 five-star reviews, 1,900 four-star and only 61 at one or two stars.

Value depends on what you expect. The course was updated in May 2026 and has six quizzes, but no assignments or projects, so this is watching and note-taking rather than doing. Next to the electronics, ROS 2 and systems engineering courses it sits beside, it's the only one that explains a physical machine rather than a tool or a process. A good first step if you want to understand why a wing lifts before opening a textbook; a poor one if that is already familiar ground.
