HELICOPTERS: How They Work

by John Lewellen ‧ RELEASE DATE: Jan. 1, 1954

From the author of the excellent Birds and Planes: How They Fly (1952, p. 42) comes another clear and readable explanation of rotary wing aircraft, their history, inner workings and practical uses. In the opening chapter a personal account of a flight with a friend from Chicago to a distant suburb in bad weather gives a play by play description of a helicopter at work. Chapters on mechanics, engineering and types of helicopters follow and with interest rather skillfully aroused, even the uninitiated will be able to understand the processes of speed by rotation rather than forward movement, tilting by gyroscopic procession and so forth. There is a report on Sikorsky's work and future uses, and by the end the helicopter has taken on the fascination of a craft we may all be flying around in tomorrow.
