Structural Mechanics, Manufacture and Design Compromise
Ideally, centrifugal compressor impellers have infinitely thin airfoil blades that are infinitely strong, each mounted on an infinitely light rotor. This material would be infinitely easy to machine or cast and infinitely inexpensive. Additionally, it would generate no operating noise, have an infinite life while operating in any environment.
From the very start of the aero-thermodynamic design process, the centrifugal impeller’s material and manufacturing method must be accounted for within the design. Whether it be plastic for a vacuum cleaner blower to aluminum alloy for a turbocharger, steel alloy for an air compressor or titanium alloy for a gas turbine. It is a combination of the centrifugal compressor impeller shape, its operating environment, its material and its manufacturing method that determines the impeller’s structural integrity.

Famous quotes containing the words structural, manufacture, design and/or compromise:
“The reader uses his eyes as well as or instead of his ears and is in every way encouraged to take a more abstract view of the language he sees. The written or printed sentence lends itself to structural analysis as the spoken does not because the reader’s eye can play back and forth over the words, giving him time to divide the sentence into visually appreciated parts and to reflect on the grammatical function.”
—J. David Bolter (b. 1951)
“The great cry that rises from all our manufacturing cities, louder than the furnace blast, is all in very deed for this—that we manufacture everything there except men.”
—John Ruskin (1819–1900)
“What but design of darkness to appall?—
If design govern in a thing so small.”
—Robert Frost (1874–1963)
“The trail of the serpent reaches into all the lucrative professions and practices of man. Each has its own wrongs. Each finds a tender and very intelligent conscience a disqualification for success. Each requires of the practitioner a certain shutting of the eyes, a certain dapperness and compliance, an acceptance of customs, a sequestration from the sentiments of generosity and love, a compromise of private opinion and lofty integrity.”
—Ralph Waldo Emerson (1803–1882)
