Episode 405: RC Ornithopter Concept

Matt is a fan of both aviation and historical engineering, so he has decided to bring those two worlds together in an attempt to recreate one of the most elusive designs in aeronautics: the ornithopter. The ornithopter is a flapping-wing flying machine that is fairly easy to build small models of, but--like most novel aircraft designs--becomes exponentially more unwieldy at larger scales. Granted, RC ornithopters DO exist, but they're very small and do not mimic the form of a human-carrying fuselage. Will Matt succeed at creating a larger-scaled ornithopter and revolutionize powered flight? Or will he return to his bench and the idiomatic drawing board? Either way, it's going to be an interesting ride!

    I recall that Markus Fischer demonstrated a seagull-sized bird at one of the TED talks back in 2011 which was pretty impressive.

    May be of interest to those who haven't already seen it.

    Interesting project, but you should take a hard look at weight reduction with that low of a flapping speed.

     

    Have you considered trying to build Davinci's flying screw?

    Dave, you're a man after my own heart. I'll just have to find a place to test it!

    Thanks, DAB! Yeah, weight/balance was by far my biggest factor in trying to get the craft right. The balance was okay, with CG being right under CL, but I just had way too much weight for the available lift! Of course, my solution for securing the wings to the flapping mechanism could've been a bit more sturdy, too. It's a learning experience!

     

    As for the flying screw, that might be a fun build, but there's not much for controls on that rig! I think the autogyro might be a more practical build, but I'm not afraid to try....

    Working ornithopters are extremely cool, but they usually take teams of engineers to get just right. Any bigger and your weight ratios start to get crazy (as mine did). This one is just amazing!

    I'm in southern California; I don't need an earthquake machine!

     

    Though it might be fun to try....

     

    Maybe a model version? A resonator cannon?

    You could perhaps consider having a go at the Cornelius Drebbel (1620) rowing submarine ?

     

    Fun with linkages and buoyancy ( oh and ingress of water... )
