	Well, our problem is this: It is presently fairly difficult to calculate 
the drag and lift of a given air foil very precisely.  We will solve this problem,
or make a large step in solving the problem, by calculating the drag and lift
of an airfoil of a constant shape, in different elements of the periodic table,
and displaying (or representing) the results visually in a two-dimensional 
diagram, by the use of a computer.  We are later going to convert the two-dimensional
diagram into a three-dimensional rendered graphic, with an image package.  It is 
fairly easy, we are told, to convert a two-dimensional graphic into a three-
dimensional wonder of computers.

	What we are presently doing, we believe, would simplify a lot of the 
hassle which is involved in calculating the drag of an air foil in the real 
world.  Unfortunately, we will most likely not be able to make the air foil 
anything but a constant shape, since we have only a little bit of time allotted
to us, and because right now we are just concerned about getting the project 
finished by the deadline.

	We are presently working on our code for the program, writing in C++. 
The beginning of our pseudocode is included at the end of this document.  We have 
read a few books on introductory aerodynamics, which has helped us to find the 
equation to calculate drag and lift, namely Bernoulli's Equation, which is:

Along with the equation for drag:

	We then interpreted this into an algorithm or equation that may be read 
by the computer.  We expect to have the finished, working program by the end 
of March.

What we have done so far is written the pseudocode, which is attached 
to the bottom of the document.  Pseudocode helps to outline the program, which 
is helpful to us for understanding the steps that are involved.  We have also 
researched the topic of aerodynamics quite a bit, which has taught us a lot on 
the subjects of aerodynamics and fluid dynamics.  

Our plan is to calculate these equations on the supercomputer to which 
we have been given access.  The problems are most likely not too complex, but 
it would speed up the running and execution of our program by quite a bit.

In the end, we hope to eliminate the cost of high-performance windtunnels
which can be very expensive.  We are only a few months away from achieving the 
expected results of our project.

We would like to thank Mr. Arlee Smith, and Mr. Roy Hogan for offering their
generous help and resources to us.  We would like to thank Mrs. Cheri T. Burch
for being our teacher and helping us become involved in the NMSCC.  We would 
also like to thank the committee that puts NMSCC together, because they are 
doing a great job.

Here is the pseudocode that we have so far:

	1.1 	Declare Variables
	1.2 	Format Files
	2.	Prompt user for element
	2.1	If element is solid loop back to 2.
	2.2	If element is liquid or gas continue
	3.	Call to periodic table file for element stats	
	3.1	Recall the effects of the specified density
	3.2	Save density effects for later use
	3.3	Prompt user for time limit of visual demonstration
	4.	Print airfoil to the screen
	4.1	Mimic the effects of the saved density on the printed airfoil
	4.1.1 	Redraw 45 times a second
