Τι μπορεί να προκαλέσει η έλικα ενός αθώου drone; Δεν θα πρέπει να αποτελεί έκπληξη ότι μια γρήγορη περιστροφή κάποιας λεπίδας μπορεί να προκαλέσει σοβαρές σωματικές βλάβες (ακόμη και αν η εν λόγω λεπίδα είναι κατασκευασμένη από ένα εύκαμπτο υλικό όπως plastic or carbon).
Researchers at the Drône Research Laboratory of Aalborg University have tried to find out the damage that can be caused by twins of different drone to a large piece of pork (which has similar consistency to human skin and muscles).
It should be mentioned that the laboratory carried out the tests on the propellers of the drones under very specific controlled conditions. In other words, if you try it with the drone you have on home you will cut your hands.
How do propellers fall on pork when traveling with about 20 mph?
The carbon propel pinches in the pork with the least possible speed (carbon fiber is known for its strength), while the plastic propeller has little difficulty in impacting:
Considering the video shot with a high-speed camera at 3200 fps, it may seem like the drone does not move too fast. So the lab also published, and a video at normal speed:
Of course this is not the first time someone has tested drónes for possible injuries.
Οι Mythbusters δοκίμασαν αρκετά νέα models drone πέρυσι και κατέληξαν στο συμπέρασμα ότι τα μικρά και τα μεσαία μοντέλα drone, είναι γενικά ασφαλή.
But the bigger ones drones they can occasionally cause real damage:
Naturally, laboratory conditions can not be fully proportional to real conditions, but these investigations may eventually lead to safer propellers that break before serious damage is caused.
