He satisfied himself that all such propulsion in Nature is produced by oblique action; though, in common with all practical men, he at first supposed that it was inseparably attended by a loss of power.
We may add that in the Princeton was exhibited the first successful application of screw-propulsion to a ship of war, and that she was the first steamship ever built with the machinery below the water-line and out of the reach of shot.

The resistance necessary for propulsion will not be situated at the circumference of the wheel?
Is the screw propeller as effectual an instrument of propulsion as the radial or feathering paddle?
The engines employed for the propulsion of screw vessels are divided into two great classes,--geared engines and direct acting engines; and each of these classes again has many varieties.
There is more slip in the latter case, but there is also more engine power exerted in the propulsion of the ship, from the greater speed of engine thus rendered possible.
Is the whole power expended in the propulsion of a vessel consumed in moving aside the water to enable the vessel to pass?
Will you describe the principal features of the kind of steam engine employed for the propulsion of vessels?
He soon after went to Buffalo, and contracted for a boat to be built, with two of his Archimedean screws for propulsion by steam.
The history of the experiments for means of propulsion on our canals shows that no system has been developed by means of which the carrying power of these great channels of communication can be made available by steam.
An endless-chain propulsionwas tried upon the Western Division, without success.
Steam was also applied to the propulsion of boats in this decade and reached the practical stage when Fulton built the Clermont in 1807.
This is of highest importance on submarines and Diesel engines are commonly used for propulsion on the surface or to drive the generators which charge the storage batteries for submerged travel.
The Savannah made the trip from Savannah to Kinsale in 23 days and was under steam propulsion for only 80 hours of this time.
Although the balloonist has no means of self-propulsion and must drift with the winds, he is capable of controlling motion in the vertical direction and can choose the particular air currents on which he desires to ride.
The propulsion would be the same were the jet discharged in the open air or in a vacuum or against a solid stone wall.
In either case propulsion is effected by the difference of air pressure on the opposite sides of the car.
From time to time other means of propulsion were proposed and tried.
Trevithic applied steam power to the propulsion of a coach in 1801.
He provided himself with wings and, jumping off a height or running down a slope, depended upon gravity to furnish him with the necessary propulsion through the air.
The air frame and propulsionpeople can keep on, because they don't use the gadgets.
Similarly, the projects had air-frame departments, propulsion departments, instrumentation departments, and administrative departments.
Any one who understands the elementary principles of building and propulsion of boats will realise that volume of water of itself fixes limits for speed of vessels in it.
Miller and Symington, on the utilization of steam as a means of propulsion for vessels.
In addition to oars, sails were used as a means of propulsion whenever the wind was favourable, but not in action.
Apparently, oars were not used in this particular boat; the propulsion was effected by means of a single square sail.
