Blog day 6

Today as we did more reasearch on the sr-71 Blackbird, we learned that the onl fuel blackbird's could us is a low vapopr pressure fuel that would not boil over 300 degeress farenheit. This fuel is called jp-7 which is the only fuel that is used by the blackbird. We also learned that the BlackBird keeps accelerating and accelerating until it reches mach 3.

Blog Day 4

Today we watched a video on the SR-71. We learned that the tempature effects evrything on the plane. The faster the plane goes, the hotter it gets. The plane is made out of 90% titanium. The C.I.A. buys the titanium from the soviet union. The titanium skin on the plane reaches up to 1,000 degrees farenheit, which causes the plane to expand about a half a foot. The plane has to go through a heating and recooling process when it lands to put the plane back in its original shape. The SR-71 has unsealed fuel tanks to keep the plane cool. http://www.youtube.com/watch?v=a_-mCPA_Gk0
