Abstract: A system and method for controlling a multi-rotor aircraft that implements the unconventional use of an odd number of rotors. The odd or auxiliary rotor is designed to be smaller in diameter than the remaining main rotors and accordingly generates a smaller unbalanced torque and pitch on the aircraft. Additional configurations implement the use of smaller thrust rotors that can be used to generate thrust as well as control yaw and thus counteract any remaining unbalanced torque from the odd auxiliary rotor.

Abstract: A thin oil film having parylene irregular dendritic-like columns extending from one side to another exhibits hydrophobic properties that can be used as a corrosion resistant coating or water-repellant, biofouling resistant surface. This parylene-in-oil layer can be paired with an adjacent layer of solid parylene that it overlays or underlays. The solid parylene cross polymerizes with the parylene dendrites, keeping them in place as well as the oil film. The parylene dendrites are fabricated by chemical vapor deposition (CVD) of parylene over the oil layer, the dendrites self-forming from the bottom to the top. Continued CVD over the dendrites can produce a top layer of solid parylene. Etching the solid parylene away can result in a water repellant, anti-biofouling surface.
