Cyclogyro

This is a concept UAV cyclogyro aircraft. This means that it is a VTOL plane that is propelled by cyclorotors, which are the equivalent of the Voith Schneider propeller in boats. These rotors are capable of achieving higher efficiency at greater speeds than regular propellers, and also produce less noise. Nowadays there aren´t many of this aircraft, just some prototypes from universities, Cyclotech and D-dalus; and that´s why I tried to design my own aircraft. This cyclocopter is a rc aircraft to simplify the design. The cyclorotor has all of the internal components and it moves and works (at least in the Catia assembly), but the internal structure that holds the surface and the internal components is missing, I haven´t designed yet. The cyclorotor´s blades use a NACA 0015 airfoil, because many studies that I found say that it is the most efficient one for small size cyclocopters. The main structural plates of the rotor are meant to be made from carbon fiber, and the blades are meant to be 3D printed with an hexagonal infill so that they don’t twist during flight. Over the carbon fiber plates there will be 3D parts that will hold a bearing wherever there is a rotation axis, that has to be placed inside the piece while printing so that it stays inside the PLA piece after the piece is done. This helps reducing the amount of glue and screws used.

The bearing size is 7mm because its’s the easiest to buy at local stores. The metallic tubes and connectors are from rc cars connectors because they are stronger than regular rc plane ones (https://www.amazon.es/Rayocon-Actualizaci%C3%B3N-Varilla-Tracci%C3%B3N-Accesorios/dp/B092ZXRPT6/ref=sr_1_11?__mk_es_ES=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=varilla+servo+coche&qid=1630633232&sr=8-11) <- link to see the original ones.I recommend you open the Cyclogyro or Cyclorotor Catparts at the Catia_files folder if you have this program, but I also left a stp version for those who don’t use it.
