A number of units of Cornell University--particularly those associated with the College of Engineering--produce technical reports or did so in the past. Some of these reports are online, some are in print, and some are not available at all at present.
Below are some sources of tech reports from Cornell:
From 1946 until 1972, Cornell operated the Cornell Aeronautical Laboratory in Buffalo, New York, after which time operations were spun off into the independent CALSPAN corporation, which was later acquired--but later again spun off--by General Dynamics.
The Cornell Aeronautical Laboratory produced a large number of technical reports, some--though not all of which--are held by Cornell University Library. Some are in print, some are online, some are in microfiche format.
