Aeronautic turbines

The major goals for aeronautic turbines design are a compact flame, stable combustion over a wide operating range, and low emission levels. Another crucial point...

Reynolds numbers are of value in the various fields because lesis of models are directly comparable to full-scale results of geometrically similar shapes if the Reynolds ratio for the model equals that of the actual or full-scale project. This has its practical applications in the field of hydrodynamics, in the study of water resistance of hulls or floats, and in the study of water velocities, levee problems, etc., of large rivers. It is used also to establish the best proportions of hydraulic turbines through the use of models. Much of the science of aeronautics rests upon experimental data obtained in wind tunnels. Dangerous inaccuracies might exist in drawing conclusions for actual construction from model tests, unless either the model were, tested at a Reynolds number equal to that of the completed project, or due corrections and allowances were made for the Reynolds number.

The EE methodology in LES used throughout this work is taken from previous work [280 328 347 346[ where the validity and limitations have been discussed extensively, and it is not the purpose here to discuss further theoretical aspects. Despite the known limitations of such methodology, it is interesting to evaluate the potential and accuracy of the existing models when applied to realistic geometries and flows. This is the objective of the present discussion in the case of aeronautical gas turbines.

He was awarded the U.S. Medal for Merit and Great Britain s King s Medal for his service during World War II as Chief of the National Defense Research Committee s Fire Warfere Section and on the Gas Turbine Committee of the National Advisory Committee for Aeronautics. After the war he was Chairman of the National Academy of Sciences Fire Research Committee for 10 years. He helped initiate and served for... 

These processes are well suited to the production of very large parts ranging from turbine blades and boats to rail cars and bridge decks with relatively low equipment investment. Compared to the conventional composite fabrication methods used in the aeronautical field, these infusion processes are an ideal technique using low cost materials without prepregs and autoclaves. 

The resistance of fibre-enhanced polymers to salts and acids has, however, kept them in active use in technical buildings. Silos and large halls are quite often raised using these materials. In the meantime, the industry has been able to gather a great deal of knowledge and experience through the construction of turbine blades for wind farms and the establishment of this technique in boat and yacht construction, as well as in the automobile, aeronautics and aerospace industries. 

Folsom lectured and contributed widely to the transactions and the scientific societies on the transportation of sand in pipelines, the design of propeller pumps and fans, the axial adjustment of deep-well turbine pumps, the performance characteristics of deep-well turbine pumps, the code for measurement of water discharges, nozzle coefficients for free and submerged discharge measurement structures, manometer errors, laboratory manuals and jet propulsion engineering. He was a member of the American Rocket Society ARS, the American Society of Engineering Education ASEE, the Aeronautical Society, and a Fellow of the American Society of Mechanical Engineers ASME. 

He emigrated in 1900 with his parents to the United Kingdom, and to the USA in 1915. He began his engineering career in 1929, working mainly in the fields of gas turbines and jet propulsion. He was an early pioneer in one of the first rocket companies of the USA fi om 1942 to 1946. He held between 1946 and 1953 a joint appointment between aeronautical and mechanical engineering at Piu due University,...
