I want to know how the individually controlled feather like winglets work on controlling and rolling by reducing drag.(concept of airbus bird's of prey) I just need a detailed review of the aerodynamics and its mechanics and how it reduce drag and what are its effect on L/D ratio etc as i am a aeronautical student i wish to know more about it on the futuristic design so it can be helpful in my projects😁
The "Bird of Prey" is nothing more than an artist's conception at this point so there is nothing to review from a mechanical design standpoint.
Somebody thought it would be neat to make a plane that looked like a bird, but the methods by which birds achieve flight is far different than in modern aircraft. I don't believe there are any practical advantages to having a control surface that looks like a feather, and "function follows form" isn't a design strategy that has been proven to work.
I doubt we will ever see one fly, but it would make a fanciful sculpture, like this:
