- 3. Definition • Aerodynamics is the study of the motion of air, particularly when it interacts with a moving object. • In physics the term dynamics customarily refers to the time evolution of physical processes.
- 4. Factors that Affect Aerodynamics The Object: Shape & Size The Motion: Velocity & Inclination to Flow The Air: Mass, Viscosity, Compressibility
- 5. Four Forces of Flight • Lift is a force used to stabilize and control the direction of flight. • Drag is the aerodynamic force parallel to the relative wind. • Weight is the force generated by gravity on the rocket. • Thrust is the force which moves the rocket forward.
- 6. Weight • Weight is the force generated by the gravitational attraction on the rocket. • The gravitational force is a field force; the source of the force does not have to be in physical contact with the object. • Gravity affects the rocket whether it is stationary or moving (up or down).
- 7. Thrust Thrust is the force applied to the rocket to move it through the air, and through space. Thrust is generated by the propulsion system of the rocket through the application of Newton's Third Law of Motion. The direction of the thrust is normally along the longitudinal axis of the rocket through the rocket’s center of gravity.
