Introduction  Aerodynamics is a branch of dynamics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies in motion relative to such fluids. We can simply define it as Aerodynamics is the study of objects (cars, airplanes, etc.) moving relative to a fluid, such as air. Relevant Properties That Affect the Aerodynamics  There are many factors that affect aerodynamic forces. The Object Geometry has a large effect on the aerodynamic forces generated by an object. Lift and drag depend linearly on the size of the object moving through the air. The cross-sectional shape of an object determines the form drag created by the pressure variation around the object. Motion of the Air Lift and drag are associated with the movement of the rocket through the air, so lift and drag depend on the velocity of the air. Lift and drag actually vary with the square of the relative velocity between the object and the air. The inclination of the object ...
