He succeeded also in manufacturing some of his designed aircraft characterized by his designed innovative features. On that sphere he experimented the most important one, a patent of a particular cowling to be applied on a radial engine, that allowed to remarkably increase the aircraft aerodynamics penetration and allowing at the same time an efficient system of temperature regulation of the aircraft itself. This project, known as Anello Magni, has been further developed by the National Advisory Committee for Aeronautics, becoming known as NACA cowling
