So I have tested quite a few different platforms to use for UAV work, including a few flying wings, but, I can not seem to understand why in the SUAS world so many platforms are flying wings?
From my testing here are the pro's and con's I have found:
- Good MTOW for wing span
- decent crash resistance
- Easy to fit wide cameras
- Difficult launching, can be dangerous as prop is usually in the rear
- Very CG dependent
- Less efficient in practice
- No flaps
- Tip stalls/death spirals
- difficult to adjust CG when changing payloads
- Less stable in wind (No yaw control)
Am I missing something as to why so many fixed wing UAV's coming from the DIY community are flying wings?
Our testing has shown cargo plane style twins with fairly high aspect ratio and high aspect ratio gliders to be the best all around platforms for UAV work (carrying payloads)
I am curious to hear from the community on your thoughts and what designs other people find effective or what I am missing about the flying wing craze.
