👉 The term "superfinical" refers to a type of aircraft designed for supersonic flight. It is characterized by its ability to achieve significant speeds (typically in the range of Mach 1) without requiring any external propulsion or power source, allowing it to fly at extremely high speeds and with minimal energy consumption. Superfinical aircraft are typically designed with an advanced aerodynamic system that allows them to rapidly change their speed from zero to Mach 1. This system is called a "superlumin
