Method and system for monitoring and displaying engine performance parameters
The invention is believed a major improvement that will have a broad application in governmental and commercial aviation. It provides a dynamic method and system for monitoring and simultaneously displaying in easily scanned form the available, predicted, and actual thrust of a jet aircraft engine under actual operating conditions. The available and predicted thrusts are based on the performance of a functional model of the aircraft engine under the same operating conditions. Other critical performance parameters of the aircraft engine and functional model are generated and compared, the differences in value being simultaneously displayed in conjunction with the displayed thrust values. Thus, the displayed information permits the pilot to make power adjustments directly while keeping him aware of total performance at a glance of a single display panel
Both Sides of Our Mouths: Contemporary Legends as a Means of Dissent in a Time of Global Modernism
The legend is a permanent fixture of human societies. Though the legends themselves are permanent, their functions and meanings can fluctuate as the context in which they are told and retold shifts. As societies move through history, certain authoritative institutions create narratives that direct those societies and frame debates within them. Issues neglected by these institutions yet experienced by members of the population can be said to be unconstructed. Social problems that have achieved some level of construction inevitably provoke those who dissent from those constructions.
In these situations, members of a society look for alternative means for talking about these problems. Often they turn to the contemporary legend for this purpose. This study reviews a sample of the most popular legends in the early part of 2012 to determine the ways members of American society were dealing with the unconstructed social problems of that time
Heat transfer to fuel oil in viscous flow-characteristics of a fin-type heat exchanger.
A unit was constructed for the study of film heat transfer coefficients of a heavy fuel oil in viscous or streamline flow. The heat exchanger was of the shell and tube type, having extended longitudinal steel fins welded to the tube. Auxiliary equipment consisted of an oil pump, oil storage reservoirs, piping, and means for measurement of temperatures and oil flow rates. The unit was operated both as a fin type heat exchanger with the oil in contact with the finned surfaces, and as a straight tube and shell exchanger with the oil on the tube side. Oil flow rates and temperatures were varied over a wide range. The data obtained was calculated by the means of existing empirical equations, and the results were compared with those of previous investigators and with the proposed correlations by plotting. The experimentally determined film coefficients obtained on the exchanger when operated as a fin type were found to be in agreement with the best existing correlation. Coefficients determined on the straight tube and shell exchanger were found to be forty per cent higher than the values predicted by this correlation. A comparison was drawn between the exchanger as a fin type and as a shell and tube type. The fin type was found to transfer approximately four hundred per cent as much heat per unit length of exchanger as did the straight shell and tube type. It is believed that a considerable saving would be effected by the use of a fin type exchanger in any application of heat transfer in which one fluid film definitely controlled the rate of heat transfer
Oral History Interview: Abbott M. Smith Jr.
This interview is one of series conducted concerning the Oral History of Appalachia. Mr. Smith was a bombardier in the 303rd Bomb Group, U.S. Army Air Corps during World War II. He discusses: his war-time experiences; his work helping to test proximity fuses in preparation for the dropping of the atomic bomb over Japan; humor as an antidote against combat fatigue; medical care, food, accommodations, and social life while the 303rd was based in Molesworth, England; the high losses of the unit; people he knew; his business life; the recent interest in World War II; and other topics.https://mds.marshall.edu/oral_history/1555/thumbnail.jp
