Aviation Quotes
When once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you
... [Show More] will always long to return.
- Leonardo da Vinci
The air up there in the clouds is very pure and fine, bracing and delicious. And why shouldn't it be? – it is the same the angels breathe.
- Mark Twain
Aviation Quotes
It is possible to fly without motors, but not without knowledge and skill.
— Wilbur Wright
There are airmen and there are pilots: the first being part bird whose view from aloft is normal and comfortable, a creature whose brain and muscles frequently originate movements which suggest flight; and then there are pilots who regardless of their airborne time remain earth-loving bipeds forever. When these latter unfortunates, because of one urge or another, actually make an ascension, they neither anticipate nor relish the event and they drive their machines with the same graceless labor they inflict upon the family vehicle.
— Ernest K. Gann
The way I see it, you can either work for a living or you can fly airplanes.
Me, I'd rather fly.
— Len Morgan
What is Aerodynamics?
❑ Aerodynamics - a branch of fluid dynamics
▪ Concerned with the study of forces and gas flows.
▪ The sub-discipline of fluid mechanics that studies fluids (liquids and gases) in motion.
❑ The solution of an aerodynamic problems involve
▪ Calculating for properties of the flow (e.g., velocity, pressure, density, and temperature, as a function of space and time)
❑ Understanding the flow pattern makes it possible to calculate or approximate the forces and moments acting on bodies in the flow.
Aerodynamic Classifications
❑ External aerodynamics is the study of flow around solid objects of various shapes.
▪ Evaluates the lift and drag on an airplane
▪ The shockwaves that form in front of the nose of a rocket or
▪ The flow of air over a wing are examples of external aerodynamics.
❑ Internal aerodynamics is the study of flow through passages in solid objects.
▪ Studies the airflow through a jet engine or through an air conditioning pipe.
Basic Quantities
❑ Basic Quantities
▪ Force pounds (lb)
▪ Distance feet (ft)
▪ Time seconds (sec)
❑ Fundamental Units
▪ Velocity (distance/time) ft/sec (fps)
▪ Area (distance squared) square ft (ft2)
▪ Pressure (force/unit area) lb/ft2 (psf)
▪ Acceleration ( velocity) ft/sec/sec (fps2)
