Quest for Performance

Book excerpt: This provides access to a NASA History Office publication, NASA SP-468, by Laurence K. Loftin, Jr, NASA Scientific and Technical Information Branch, Washington, D.C. 1985. It traces the technical development of the airplane since World War I. It describes significant aircraft that incorporated important technical innovations and served to shape the future course of aeronautical development, as well as aircraft that represented the state of the art of aeronautical technology in a particular time frame or that were very popular and produced in great numbers. Primary emphasis has been placed on aircraft originating in the United States. The discussion is related primarily to aircraft configuration evolution and associated aerodynamic characteristics and, to a lesser extent, to developments in aircraft construction and propulsion. The material is presented in a manner designed to appeal to the nontechnical reader who is interested in the evolution of the airplane, as well as to students of aeronautical engineering or others with an aeronautical background.
