I was sneaking around the net looking for information on "engineering graphics" for a paper I'm preparing. :roll:

I figured that I could interest kids with a picture of the SR-71 :twisted: , a high speed high altitude spy plane known as the "Blackhawk" ( :?: pic for the aircraft buffs [url="http://www.dfrc.nasa.gov/Gallery/Photo/SR-71/HTML/EC94-42883-2.html"]http://www.dfrc.nasa.gov/Gallery/Photo/ ... 883-2.html[/url] )

I downloaded the flight manual for this monster to get the graph that shows the operating limitations at all altitudes and speeds (up to 3.2 times the speed of sound, and 85,000 feet) 8)

:idea: I had my start and went after more graphs and charts that when put together make this graph understandable.

Then I hit [url="http://www.grc.nasa.gov/WWW/K-12/airplane/short.html"]http://www.grc.nasa.gov/WWW/K-12/airplane/short.html[/url] :wink:

Here is a list of all the topics available from the Beginner's Guide to Aerodynamics site. Clicking on the title will deliver a page with a slide and a scientific explanation of the contents. Click on the word "Animated" for the animated version of selected pages. If the number and variety of pages seems too intimidating, consider taking one of our Guided Tours through the web site.

The site includes teacher and student notes [url="http://www.grc.nasa.gov/WWW/K-12/aeroact.htm"]http://www.grc.nasa.gov/WWW/K-12/aeroact.htm[/url]

Maths and science people - you've gotta go there. :arrow: :arrow: :arrow:

I think this is the best example of an on line learning project and what's more its free, no registering, signing up, paying a fee, or the secret handshake to access. Maybe we could all learn from the initiative!
