    Need help on designing a conceptual HALE UAV

    There probably isn't a tutorial, however you could email the author(s), e.g. Palacios, for an example, e.g., test driver, you could learn from. If you started from scratch, then you would need to have a structural model of the aircraft that you could use as input to the Python/C++ code. For a...

    A book for designing RC aircraft

    What you're asking for is discussed in undergraduate student vehicle design courses (usually in the senior year as a capstone project where they build/fly their designs). You should be able to find resources online at various universities. Here's a Texas A&M University course syllabus I googled...

    Need help on designing a conceptual HALE UAV

    See if you can get an academic copy of ASWING. You need a software that can assess the fluid structure interaction of flexible wings inherent to HALE-type aircraft. At the very least, you could use AVL to understand the stability & control aspects of your aircraft design. If you want a Python...

    How does control theory help engineers understand and predict system behavior?

    The difference in the example you gave between thermodynamics and control theory is in the way you learn about systems. The way you learned thermodynamics is prescriptive, i.e., if X happens, do Y. Control theory is in developing the prescription itself. It is possible for engineers to learn...

    Physically measuring forces of gun recoil

    Probably late, but whatever ... It may be possible to use an old smartphone accelerometer to estimate the peak force by attaching the phone to the side of the gun ... or buy an expensive accel.

    Vertical movement turning a gear

    Perhaps the following book could be an inspiration: https://www.amazon.com/dp/1603863117/?tag=pfamazon01-20Instead of the rack and pinion described earlier, you can get uniform circular motion from a modified pinion. Here's a video of the design:
