What is Aeronautics?

Definition


Aeronautics is the study of the science of flight. Aeronautics is the method of

designing an airplane or other flying machine. There are four basic areas that

aeronautical engineers must understand in order to be able to design planes. To

design a plane, engineers must understand all of these elements.



Design Process


1 Aerodynamics is the study of how air flows around the airplane. By studying the

way air flows around the plane the engineers can define the shape of the plane. The

wings, the tail, and the main body or fuselage of the plane all affect the way the

air will move around the plane.




2. Propulsion is the study of how to design an engine that will provide the thrust

that is needed for a plane to take off and fly through the air. The engine provides

the power for the airplane. The study of propulsion is what leads the the engineers

determine the right kind of engine and the right amount of power that a plane will

need



3. Materials and Structures is the study of what materials are to be used on the

plane and in the engine and how those materials make the plane strong enough to fly

effectively. The choice of materials that are used to make the fuselage wings, tail

and engine will affect the strength and stability of the plane. Many airplane

materials are now made out of composites, materials that are stronger than most

metals and are lightweight.



4. Stability and Control is the study of how to control the speed, direction,

altitude and other conditions that affect how a plane flies. The engineers? design

the controls that are needed in order to fly and instruments are provided for the

pilot in the cockpit of the plane. The pilot uses these instruments to control the

stability of the plane during flight.
