Hey everyone - first post, so please be gentle!
I've been meaning to get into electronics for a long time and more often than not the ubiquitous UAV comes up as an ideal first project to learn many of the basics. The fact that I'm an aviation and space nut is just a bonus!
I know that putting together pre-made kits is one way of learning some of the basics, but personally I've always felt that I learn more by designing and building something from scratch. That being said, I also always seem to make things difficult for myself by (unintentionally) over complicating things due to a lack of knowledge. Just the other night I was thinking about how to use magnetic bearings to get higher performance out of propeller systems, and after several hours of thinking and research, I realised that I had ended up re-inventing the brushless motor :D
So. For my first question, I've been looking into UAVs and noticed that most, if not all, rely on the direct thrust provided by the propellers to maneuver. Although this obviously works well and is probably the way I'll end up going, I've been thinking of a potential UAV design which uses EDFs, or some similar ducted system to gather thrust and channel it all into a kind of central manifold. This manifold system would then redistribute the total available thrust to various thrust reaction "nozzles" (for want of a better word) according to the needs required by the maneuvers in progress.
So the idea is that instead of driving the aircraft off of the raw thrust of the propellers, I would refine the system through a process of collecting the total available thrust and then redistributing it in a more precise way to allow for finer control and possibly a larger range of maneuvers.
I know this idea might be a bit odd, and probably isn't viable, or practical, but I enjoy challenges and the learning that comes with them, plus I think designing and building something a little bit different from scratch will help me to learn more than just copying existing designs.
Any thoughts or suggestions? I'm open to criticism and any feedback.
Thanks in advance!
