Evolution of The Curtiss Design
Due to the difficulties obtaining suitable training aircraft, the Walsh brothers decided to build their own trainers, initially based on this pattern. Over the next four years they produced a series of four flying boat designs, evolved from, but bearing little resemblance to the original Curtiss model. The last of the Walsh Brothers designs, the Type D of 1919 was an aerodynamically and hydrodynamically advanced machine, with a powerful Beardmore engine.

Famous quotes containing the words evolution of, evolution and/or design:
“Like Freud, Jung believes that the human mind contains archaic remnants, residues of the long history and evolution of mankind. In the unconscious, primordial “universally human images” lie dormant. Those primordial images are the most ancient, universal and “deep” thoughts of mankind. Since they embody feelings as much as thought, they are properly “thought feelings.” Where Freud postulates a mass psyche, Jung postulates a collective psyche.”
—Patrick Mullahy (b. 1912)
“The evolution of sense is, in a sense, the evolution of nonsense.”
—Vladimir Nabokov (1899–1977)
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
