Compressor Building Hoosac Tunnel Then and Now

In the first days of tunnel construction the blasting holes in the rock were drilled by hand. This was a slow and dangerous job especially for the man that held the drill bit. In 1866 the first pneumatic drill started to work in the tunnel. The picture to the right shows the air compressor building built along the bank of

Failure Analysis of a Large Wind Tunnel Compressor Blade

A failure analysis was performed to establish the cause and prevent the recurrence of a 2014-T6 aluminum compressor blade failure in a large NASA-Ames Research Center wind tunnel. A metallurgical failure analysis showed that a 0.13 mm (0.005 in.) deep scratch in the shank of the blade had acted as an initiation site for a fatigue crack.
