Well the fuselage is like a tube right, so the air goes all around it. The wings are curved at the front so wind has to split which gives it lift (use this link to try and under stand it may be a bit difficult) http://en.wikipedia.org/wiki/Lift_(force)
(aerodynamic means affected by motion through the air, or streamlined)"The aerodynamic design of the airplane allows it to fly faster, and use less fuel.""The aerodynamic pressures on a rocket can cause it to break up if it is not properly aligned in flight."
The fuselage of an airplane is the body of the airplane so it would be the main part of the plane and holds everything together. It is in a long tube shape so it can be aerodynamic.
It is made from an element with a lower density because it would be lightweight and aerodynamic
Airplane wings are shaped like a bird's wing. They are thick at the front and thin at the back. This form of shape is more aerodynamic.
Airplanes have become more aerodynamic. The have become much more expensive. They have become faster.
Yes, the design of a paper airplane cane help it to fly farther. The more aerodynamic the design, the better the plane will fly.
The wings push air down, creating lift. Aerodynamic force causes drag and thrust to keep the airplane steady. They have to be made a certain way (aerodynamic) for this to work.
Airplanes have become more aerodynamic. The have become much more expensive. They have become faster.
It was a small bi plane. Biplane are planes that have two wings. This plane's design was not aerodynamic. It created much drag.
The center of gravity is a point on the airplane that the airplane would balance while sitting on the ground. The center of gravity or also called "the CG" is important in trimming the aircraft in flight as the weight has to balance out the forces on the wing. It is also important in aerodynamic maneuvers as the G-forces act through CG.
Aerodynamic simulation
Engineers put very accurate models of new airplanes in wind tunnels to see how aerodynamic they are.
