Produktbeschreibung
Excerpt from Manual of Medical Research Laboratory Though the principles of aeronautics were clearly enunciated by Samuel Johnson 159 years ago in his Rasselas, Prince of Abysinia, it was not until within the last decade that air flights began to be practical. During these years infinite time and thought have been spent upon the machine. The pitch of the screw, the angle of attack, the stream line, the admixture of gasoline and air, etc., have all been studied with mathematical accuracy. But the value of the human machine is just beginning to be properly recognized. A slack control wire is not more dangerous than a weak eye muscle, a poor mixture of gas and air is not more serious than a flier with poor adaptive respiration. And a poor compression in the cylinder is not of such vital consequence as a weak heart muscle. The Laboratory, which is the workshop of the Medical Research Board of the Air Service, investigates "all conditions which affect the efficiency of pilots"; classifies fliers not only according to their efficiency, but also according to their ability to stand diminished oxygen; and instructs Flight Surgeons and Physical Directors in the reactions of the human system to oxygen want. This manual is the result of the work done in the Laboratory and it is intended for the information and instruction of those who arc interested in the medical problems of aviation. In these brief pages it has been impossible to go fully into a subject so new and so large, but it is the earnest hope that the faithful painstaking work of the department heads and their assistants may be of service in stimulating the study of conditions that are of such vital economic, military, and human value.
