Stran 1 - Smithsonian executive committee, may exercise its functions for the military and civil departments of the government of the United States, and also for any individual, firm, association, or corporation within the United States ; provided, however, that such department, individual, firm, association, or corporation shall defray the cost of all material used and of all services of persons employed in the exercise of such functions.
Stran 4 - ... operate air craft, and who determine largely the scope and character of their development; each has its aeronautic station equipped with machines in actual service throughout the year. Besides various aviation establishments, the War Department has a balloon plant at Fort Myer, Va., and at Omaha, Neb.; the Navy has its marine Model Basin, useful for special experiments in aeronautics, its extensive shops at the Washington Navy Yard, available for the alteration or repair of air craft, or the...
Stran 4 - ... with the United States Treasury, or place them otherwise, as may be required by the donor. Likewise, it can be the recipient or custodian of material objects representing any province of nature, or any branch of human knowledge or art. This unique character allows the public to anticipate or supplement the cooperation of Congress in promoting the aerodromical (aeronautical) work of the Institution.
Stran 3 - United States Bureau of Standards, from which the Secretary of Commerce has designated one representative. This bureau has a complete equipment for studying the mechanics of materials and structural forms used in air-craft; for standardizing the physical instruments — thermometers, barographs, pressure gauges, etc. — used in air navigation; and for testing the power, efficiency, etc., of aeronautical motors in a current of air representing the natural conditions of flight. In these general branches...
Stran 1 - An aeroplane or airship in flight has six degrees of freedom, three of translation and three of rotation, and any study of its behavior must...
Stran 4 - These departments, while especially interested in aeronautics for national defense, can be of service in advancing the general science. Each has an aeronautical library; each has an official representative in foreign countries who reports periodically on every important phase of the art; whether civil or military; each has an assignment of officers who design, test, and operate air craft, and who determine largely the scope and character of their development ; each has its aeronautic station equipped...
Stran 4 - Myer three lofty open-work steel towers suitable for studies in meteorology or aerodynamics in the natural wind. Furthermore, the Navy Department has detailed an officer for special research in aeronautics at one of the principal engineering schools. Because of their fundamental interest in aeronautics, each of these departments has two representatives on ¿the advisory committee, and each will be able to place at the service of the committee one or more skilled aviators and aeroplanes for systematic...
Stran 1 - States, and also for any individual, firm, association, or corporation within the United States ; provided, however, that such department, individual, firm, association, or corporation shall defray the cost of all material used and of all services of persons employed in the exercise of such functions.
