The first of the Lebaudy vessels was named the 'Jaune'; its length was 183 feet and its maximum diameter 30 feet, while the cubic capacity was 80,000 feet. The power unit was a 40 horse-power Daimler motor, driving two propellers and giving a maximum speed of 26 miles per hour.
This indicated that the loss of power from this source would be only 5 per cent., as we originally estimated. But while we could see no serious error in this method of determining the loss, we were very uneasy until we had a chance to run the propellers with the motor to see whether we could get the estimated number of turns.
Hodgson bends the arms of his propellers backward, not into the form of a triangle, but into the form of a parabola, to the end that the impact of the screw on the particles of the water may cause them to converge to a focus, as the rays of light would do in a parabolic reflector.
Probably as much now as ever there was. Why should substituting smoke-pipes for spars, and propellers for sails, kill the thing that thrills us? I've seen men washing down decks of a tropic morning, and, ninety miles inland, old Orizaba showing his white head above the clouds; and some of those men thought it was slow work and others thought it was great.
The propeller subsequently applied to the steamship 'Princeton' was identical with my said design of 1835. Even the mode adopted to determine, by geometrical construction, the twist of the blades and arms of the 'Princeton's' and other propellers was identical with my design of the year last mentioned." At about this same time, or in 1835, the attention of Mr.
It was necessary not to aggravate the damage to the screws, for if the propellers were rendered useless the situation of the aeronef above the vast seas of the Pacific would be a very awkward one. And the engineer began to consider if he could not effect his repairs on the spot, so as to make sure of continuing his voyage.
There are three lines of propellers plying between this port and Buffalo, Cleveland, and Detroit, each employing three ships, while there is an additional line to and from Chicago. They together average four arrivals weekly. The trip from Buffalo is performed in little less than a week, that being the most distant of the respective places.
Then only would they begin repairing the stern-screw; and then the aeronef could resume her voyage across the Pacific to X Island. It was important, above all things, that the "Albatross" should not be carried too far to the northeast, but unfortunately the breeze grew stronger, and she could not head against it, or even remain stationary. Deprived of her propellers she was an unguidable balloon.
It must be evident that in case of a war between this country and a mighty naval power, which we trust will never occur, the many large "clipper ships," which compose a large portion of our commercial marine, will be provided with screw propellers, and transformed into privateers.
The wind from the propellers blew hats in every direction and streamed out the hair of the men holding the aeroplane back, as if they had been poking their faces into an electric fan. Faster and faster the propellers revolved, as Frank increased the power of his mixture and advanced the spark.
