The Trial trip of the English iron Ship Warrior.
The iron-clad war steamer Warrior
has created quite as much interest in England
as did the Great Eastern
during her construction and upon the occasion of her grand debut.
The Warrior made her first real sea-going trip on the 19th of September. We find in the London Times
a sketch of the trip, from which we make a few extracts.
She answers her helm like a yacht, was most astonishingly free from vibration or movement, even going at speed, seemed light and buoyant to the gentle swell she met with here and there, and, above all, even in her unfavorable condition as to a foul bottom and the launching cleats being on, made her way through the water faster than the average of quick sea-going mail steamers.
It only wanted a stiff breeze and heavy beam sea in the channel to make the trial perfect; but neither of these was she fortunate enough to meet.
Before the middle of next month, however, she will be out of her dry-dock at Portsmouth
— at least, completely ready for sea — when it is stated she is to take a cruise in search of bad weather.
Such a search is likely to be crowned with success at this season.
The Warrior is now nearly complete.
Her internal fittings have been arranged, her stores and armament taken on board, and the iron tower on her deck erected, but so unskillfully that ‘ "it almost spoils the look of the vessel."’
The Warrior set forth with only half a dozen observers on board, and drawing twenty five feet nine inches forward, and twenty-six feet three inches aft. The Thames
was blocked with craft, and only the Warrior
's ready obedience to her helm saved her from various unpleasant chances of grounding or of running over vessels.
The engines were moving easily at thirty-four to thirty- six revolutions, but, after passing Gravesend
, the rate was increased to forty.
, an admiral was saluted with fifteen guns from the Warrior
's sixty-eight pounders.--The Times
Much interest was evinced by those on board to observe the effect of the concussion of these heavy ordnance on the great ship, and, above all, to see what foundation there was for the rumor that her narrow ports would keep in smoke enough to almost suffocate the men on the main deck.
The result, as usual, quite upset the predictions of the alarmists.
The shock of each gun was sharp and sudden, but less than half what is felt on the same occasion in wooden ships, no matter what their size.
Of smoke on the main deck there was really scarcely any; the small ports kept it out instead of in, and, when the salute was over, the main deck was almost entirely free, while the spar deck was wrapped in a dense cloud.
The Warrior's armament at present consists of two 100-pounder and four 40 pounder Armstrong
on her upper deck, with two 25-pounder Armstrong
for field-pieces and boat guns.
The whole of her main deck guns, 36 in number, are all solid 68-pounders of 95 cwt, each.
No other vessel in the world has such a terrific battery.
Eight or ten of these midships guns on each side may, probably, hereafter be changed for 100-pounder Armstrongs, but a certain proportion of 68- pounders will always be kept, partly to throw shells filled with molten iron, and partly because there is a most decided opinion in the navy that for close range they are even better than the Armstrong
Once at sea the engines were moved at the rate of forty to forty-eight revolutions, with twenty pounds of steam, and thus at three-fourth speed the vessel sped along at the rate of fourteen and one-half miles an hour.
It is believed with the engines at 58 her speed will be fully 16 miles per hour.
Nominally yielding a force of 1,250-horse power, her engines are said to have a real power of 6,000.
The cylinders are 9 feet 4 inches in diameter, and they require an evaporation of 16,250 gallons per hour.
The main steam-pipe is 2 feet 8 inches across.
The condensers form a two-roomed space 15 feet long by 12 feet broad, and 9 feet high, each compartment supplied with a 9-feet pipe for condensing purposes, and with a 7-inch pipe for conveying the hot water back again to the boilers.
There are ten boilers and forty furnaces.
Each boiler has 440 tubes.
The boilers are each 14 feet long by 10 feet 3 inches broad, and 12 feet 4 inches high.
The weight of the Warrior
complete would be 9,000 tons, or within 1,000 tons of the Great Eastern
when she was launched.
The cylinders are placed 7 feet below the line at which any fire of the enemy could reach them.
The weight of the piston and the parts connecting it with the crank is no less than 13 tons, the stroke 4 feet, and the number of revolutions calculated at 50 per minute.
Here, then, is a weight of 13 tons moving backwards and forwards 100 times in that brief interval.
The steam shaft is forged in one piece of malleable iron, thirty feet long and twenty inches in diameter, having two cranks in its length cut out of the solid.
The screw, twenty-four feet in diameter, made entirely of gun metal, and weighing about twenty tons, is one hundred and twenty feet from the engines, and is connected with the main shaft by a succession of shafts, each twenty-six feet long by eighteen inches in diameter.
The screw alley is nine feet wide by seven feet high, and at the stern there is the usual well, fitted with the hoisting apparatus for raising the screw to the deck.
The bearings on which the screw works are lined with lignumvitiœ
a very beautiful, economical, and simple application, by which the immense cost of repairs from the effect of friction on the old brass bearings is reduced to a nominal amount.
The consumption of coals required for full steaming will be at the rate of about one hundred and twenty-five tons per twenty-four hours.
At the close of her voyage of two hundred and twenty miles, the Warrior
was taken into the Portsmouth
while jubilant over the action of the Warrior
"But that the public might be incredulous at the Admiralty
being accused of any oversight, we should be inclined to say that it was a decided blunder to build ships of a Warrior class, having only one dock large enough to repair them, and even that only accessible once in each two weeks.
