INTERNET RESOURCES FOR M447:AERODYNAMICS
NASA's Beginner's Guide to Aerodynamics
is a good start ing  point for an elementary introduction to aerodynamics !
THE IDEAL FLOW MACHINE
is an interactive Java applet to experiment and visualize ideal fluid flows.
You can place singularities such sources, sinks, doublets, point vortices, etc. in uniform flow
or any combinations of these singularities and then plot the streamlines and flow field variables.
You might also want to try yet another POTENTIAL FLOW APPLET.
FOILSIM
 (created at the NASA Glenn Research Center )
 is a simple software package on the aerodynamic lift generation mechanism of airfoils and wings.
 FOILSIM (with User Notes)   is a version of the software with user notes 
You can also download your own copy by clicking FoilSim.zip.
AeroFoiL
is a shareware utility that allows you to download all the airfoils on the
UIUC Airfoil Coordinates Database Site 
and some other airfoils not falling into this database site onto
your computer and  to  conveniently view these airfoils and edit their coordinates.
You can also use a PANEL CODE to analyse and view the incompressible aerodynamic flow field
and airfoil characteristics of many of these airfoils.
COMPRESSIBLE AERODYNAMICS CALCULATOR
is an interactive Java applet to evaluate compressible flow properties
across expansion fans using isentropic flow relations
and across normal and oblique shocks using shock relations.
SUPERSONIC WING!
is an interactive Java applet to determine the aerodynamic characteristics
of supersonic wedge-shaped airfoils  using the shock-expansion theory
Linearisation of the full-potential equation by way of the small-distrubance theory enables one to develop simple and elegant estimates of airfoils characteristics in high subsonic (i.e  Compressibility Corrections) and supersonic regimes (i.e. linearised supersonic thin airfoil theory) of flight.   However in the transonic regime, the small-disturbance theory gives a non-linear equation which can be solved by numerical methods.
You can use
TRANSONIC SMALL-DISTURBANCE SOLVER
which solves the nonlinear transonic small-disturbance potential equation numerically
to visualise the structure of the flow field and the formation of shocks in the vicinity of an airfoil in  transonic flow
