View of the AEDC about as it was when I headed the UT/AEDC Graduate Study Program from 1957 to 1964. Beyond the right margin is the A&E bldg. where some of our courses were taught and we had our main offices. The tall building on the right houses the 40 by 80 foot Space Chamber where I did much of my consulting work under the guidance of Eino Latvala and Ken Tempelmeyer. The very large tubes to the left is the PWT wind tunnel with super sonic and transonic legs. I taught courses in the small building adjacent to the wind tunnel. Further to the left is the Engine Test Facility where I also taught courses. To the rear is a sphere at VKF where I also held classed and my first consulting at AEDC was with Clark Lewis on a graphite heated wind tunnel design. The water tower behind that is the location of the 200 foot deep liquid rocket test cell with other rocket test cells near by. My class schedule was usually 315 to 430 pm on Monday and 445 to 6 pm on Wednesday. Half on company time and half off. We had a fine school and it was a pleasure to work there. However, it was as a consultant that I made my first but not last mistake in dealing with Dr. Goethert. In their research to determine the heat transfer at the base of multi-nozzle rocket engines, the facilities were using a heat gauge to measure the rate of heat transfer at the rocket base. The Gauge was a copper block located at the surface of the base of the engine with a thermocouple inserted in the gauge for the purpose of measuring the variation of temperature with time. There was a simple mathematical solution for the heat transfer to such a device if the variation of temperature with time was known. However the solution assumed no heat exchange at the back or sides of the gauge. And that condition existed only for a very short time after the flow was started so the only valid data for heat transfer so obtained was the initial slope of the temperature versus time curve for the gauge. So Doc asked me to talk to the young engineer in charge of that project. I did and he bought me a temperature versus time plot for several minutes and the line wandered around sometimes up sometimes down. I explained to the young man that with the data reduction methods they were using only the initial slope of the temp - time plot meant anything and sent him on his way. Later Dr. Goethert called me into his office wanting to know why I had not reported to him on the gauge situation. I told him what I had told the young engineer and he was quite unhappy with me for not first reporting the matter to him. Despite that mistake, I had many pleasant years working with Dr. Goethert however I always felt that I was a few steps behind him in the thinking process. I still see many of my former students who did very well and are now mostly retired. There is no doubt that the test, development and research done by these folks in the AEDC facilities were a major factor in keeping the peace and assuring victory in the space race. What a privilege it was to be associated with such events. UTSI, opened in 1964. is located about 4 miles as the crow flies to the left of this photo.
