Essentially, the calculations that proved the Hypersoar concept feasible were conducted here by Dr. Pines and a student (Lael Rudd). Message From the Chair Our research expenditures within the department were 7.25 million dollars for 1999. On average, each of the faculty members within the department supported 5 graduate students. This past year our research expenditures increased to 10.5 million dollars and Greetings from the Department of Aerospace Engineering. The our publication record again increased slightly. Over the past 10 last AeroContact you may have received was in the Winter of 1998, years the research expenditures for the department have increased and our department has been growing and progressing since that from 2.8 million to 10.4 million. Research expenditures in the newsletter. For the 2001-2001 academic year, our undergraduate department on a per faculty basis are higher than any other population stands at 254, with 123 graduate students. In fall 2000 our department in the college and equals any aerospace department in faculty size increased to 18, and this fall we have increased to 20. the country. In 1999 our faculty wrote 3 textbooks, 3 chapters Drs.

The year 1999 was also our 50th Anniversary and we celebrated Dr. David Schmidt left the department after taking a 11⁄2 year that milestone with two very important events.
