The Type C-1 F. Navy Training Hydroaeroplane was flown from Hampton Roads, Va., to Rockaway, N. Y., for exhibition at the aero show. This machine is equipped with a Curtiss OXX-5 100 horse-power motor. It is an experimental type built for the navy, and has single float instead of the double floats usually employed on Boeing seaplanes. Span, both planes 43′ 0″ Over-all length 24′ 0″ Speed range 36-65 M. P. H. BURGESS COMPANY The Burgess Company exhibited a car designed for one of the “C” class twin-motored navy dirigibles. The car is of streamline form, 40 feet long, 5 feet in maximum diameter, with steel tube outriggers carrying an engine at either side. Over-all width of outriggers, 15 feet. Complete weight of car, 4,000 pounds. Seven passengers may be carried, but the usual crew consists of four. The engines are made by the Union Gas Engine Company, and are 150 horse-power each. Fuel capacity, 240 gallons; oil, 16 gallons. Four bombs, totalling 1,080 pounds, are carried at the side. The dirigible for which the car was designed is 192 feet long, 43 feet wide, and 46 feet high; it has a capacity of 180,000 cubic feet. Its high speed is 59 miles per hour, at which speed it has an endurance of 10 hours. Cruising speed, 42 miles per hour; cruising radius, 12½ hours. Climb, 1,000 feet per minute. THE CANTILEVER AERO COMPANY The Christmas Bullet has caused a great deal of comment in aeronautical circles because of its freedom from struts and wires. It is the first heavier-than-air machine built on the Cantilever truss principle, and is the result of years of painstaking investigations and experiments made by the inventor, Doctor William Whitney Christmas. The wings of the Christmas Bullet are flexible and resemble true bird form. Because of this yielding principle the machine is absolutely immune from all strain and resistance, as are “stiff-wing,” parallel-strut machines. The Christmas Bullet has a horse-power of 185. Span 28′ 0″ Length over all 21′ 0″ Weight, machine empty 1,820 lbs. Weight, fully loaded 2,100 lbs. A Liberty “6” is used, giving 185 horse-power at 1,400 R. P. M. CAPRONI COMPANY The Caproni Company exhibited a giant triplane which has been famous since 1915, when it made its first appearance. This triplane has a spread of 130 feet. It is equipped with three 400 horse-power engines, two of them in tractor position at the nose of the fuselage, and one a pusher at the rear of the central nacelle. This machine has climbed to an altitude of 14,000 feet with a ton of useful load, and with only two of the engines running. The triplane was used as a bomber, and carries a bomb compartment below the lower plane. CURTISS AEROPLANE AND MOTOR COMPANY _Curtiss J N 4 D_ The J N 4 D Tractor shown by the Curtiss Company.
