The float of a seaplane is that part of the machine which enables it to float on, rise from and alight on the water. It performs the same functions on the seaplane as the landing gear on the land machine, and is virtually a small boat divided into water-tight compartments, connected to the machine proper by steel or wood struts and wire stays of sufficient length to give good clearance for the propeller from the hull and the water.
To meet the demand for an extremely light aeronautical engine for use in pursuit machines and in training work, the General Vehicle Company of Long Island City has made arrangements with the Gnome and Le Rhone Engine Company of London to build and sell 9 cylinder 100 h.p. Gnome engines in the United States.
The Inflation and Manipulation of Dirigible Balloons
C. F. Smyth
The handling of lighter-than-air aircraft is a subject requiring much experience and study. Work of this character is being undertaken daily in Europe. A study of European methods will undoubtedly be of value for this country. The usual method of inflating a balloon is to lay it out with the top exposed.
Hardly any branch of practical airplane design offers such difficulties as the estimate of weights. A manufacturer who has built a number of machines and has kept careful weight schedules has valuable data in his possession, but is, as a rule, chary of making such data public.
