Two basic principles
of fluid dynamics underlie all objects in flight: The forces of Lift,
opposing the downward acceleration of gravity, and the forces of drag due
to air-resistance. Both
forces, properly harnessed and controlled lead to such ingenious devices
as the parachute and the helicopter. Aerodynamics, the field of fluid
dynamics involving the flow of gasses, even has applications in fields as
separate as the automotive industry, fire-safety, and
golfing. The aerodynamics of
paper airfoils, and additionally, the study of airfoils of small size and
low mass are allowing the emergence of a new generation of aircraft:
low-speed, affordable aircraft for a variety of uses: military
reconnaissance, civilian law enforcement, and interplanetary
exploration. This web-project will explore and discuss some of the fundamentals and phenomena regarding such low-speed airfoils. Constructing paper airfoils is one easy and enjoyable way to study such aerodynamics.
