What Is Aeronautics? Aeronautics is the science that underlies the study, design, and manufacture of airplanes or other aviation vehicles. Aeronautics also includes research into methods for aircraft operation within the earth's atmosphere. Aeronautical engineers apply principles and concepts of engineering to create new aircraft containing the most current and sophisticated technologies.
Aeronautical engineers use the fundamentals of aerodynamics to design aircraft that fly through the Earth's atmosphere. Aerodynamic drag. The most significant aerodynamic force that applies to nearly everything that moves through the air is drag. Drag is the force that opposes an aircraft's motion through the air, according to NASA. Drag is generated in the direction the air is moving when it encounters a solid object. In most cases, such as in automobiles and aircraft, drag is undesirable because it takes power to overcome it.
