| IMPORTANT. This will be my last weekly video for a while. I have a lot to take care of academically and can no longer produce weekly videos. I may, however, post occasionally.
As for today’s topic; feathers! Birds use what are called ‘covert‘ feathers to reattach separated airflow during what would have been a wing stall. This stabilizes the wing even in the most turbulent of airflow, and allows continued lift production well into the stall angle range for most man-made aircraft. I was inspired to look into this idea by this video from Felix Schaller, linked here: [ Ссылка ]
I experimented with the covert feathers in much the same way Schaller did; by making fake feathers from a thin, bendy material, and affixing them to the wing‘s upper surface. I used only one row of smaller feathers, but was still able to notice improvement in glide ratio and stall recovery. I have no doubt that, had I put more time into the fabrication of the feathers, and arranged more bird-like feather rows, the improvement would have been more drastic.
If you enjoyed the video, your like and subscription are highly appreciated! As I will be away from this channel for a while, I do entreat you to share my videos with friends, and to help me maintain viewership during my absence. I have hundreds of other videos, so there always something new to watch! That said, thanks for watching!
