Friday. April 20, 1956. University Daily Kausan Page 7 Engineering Power Exhibit Theme "Power in Engineering" is the theme which the mechanical engineering display will develop for the Engineering Exposition today and Saturday. Lace Planted Mid-way between Lindley Hall and the mechanical engineering laboratory the old automobile engine will be placed with signs directing the people to the mechanical engineering laboratory where the main display is located. The mechanical engineering display is contrasting an antiquated automobile engine to a model of the turbine engine, an engine design which is now being tested by several manufacturers and which will probably be applied to automobile industry in the near future. In the building there will be fuel testing equipment; an oil testing apparatus and a dynamometer, which is an engine testing apparatus which measures the horsepower and torque outputs, and which will be attached to a modern high-power auxiliary to a modern high-powered engine. A cut-away engine showing the construction and operation of a present 'a cut-away' model of a gas turbine engine, rear mounted in a mock-up auto chassis also will be shown. Not A Working Model Not A Working Model The model of the gas turbine engine is not a working model but rather a model which shows the principles involved in the engine and to compare its operation and construction to that of the present-day internal combustion engine. The central differentiating principle of the two types of engines lies in the fact that the turbine engine has a constant pressure heat-addition process; whereas in the heat-addition process of the internal combustion engine a constant volume is maintained. It is the pressure rise in the internal combustion engine which causes detonation (engine knock) and necessitates the high quality fuel requirements. Since detonation does not occur in gas turbine engine operation an advantage of this engine is simple fuel requirements. Another advantage of the gas turbine engine is the vibration free performance due to the rotational motion, as contrasted to the internal combustion engine which has reciprocating motion. Fight students will go to Winter General Hospital in Topeka Saturday to perform for the patients. The students are Roger Brown, Topeka sophomore; Sue and Ann Markwell, Gashland, Mo. sophomores; Mary and Betty Avison, Kansas City, Kan. juniors; Bonnie Dinsmore, Overland Park sophomore and Linda and Lvyn Miller, Dodge City, freshmen, musical comedy team. 8 To Perform In Topeka Lucy Wachter Gertrude Sellards Pearson Smiles because she has some short shorts and matching blouse from . . .
