THE FASTEST .-TEASIBU AFLOAT v fFrora 27is Timm, July 8.) Whatever doubts may have been r respect to the speed performances dcap.Uch vessel, were conclusive’. _ “J .h long and varied trial to whi-’ <* ™. st by the tho measured mile in St-’ She wa , t.rovssfi trt im nn f Bay last' week, bne navy l but the nub’ -•only’Uio quickest ship in tho to h£ S l .? -«>■ ship afloat, having surpaated f’ K peed realised, by the Lightning. • ati r- Ve "A»el. and cveq* outstripped tho most s l *^ l ?3 Ul^e , expectations Of Air. Barnaby. her Tho- Iri* wm in every respect eawi.tially experimental craft. There wag vothta: resembling lier in the service with reference to. the proportion of midship, section to length, the extreme fineness of her entrance and run, and the ratio of her enormous horse-power to displacement; and as a result there were only very imperfect data to guide the Constructive Department aa to her probable performances from the actual performances of previously existing ships. If was. therefore, necessary to obtain a constant for guidance hereafter, aryl to establish her co-efilcJents, and this was rendered all-the moio indispensable, seeing that the Mercury, & shter vessel, in which everything lias been saerhtoed to speed, was being’rapidly brought forward at Pembroke- The. results of her first trial at Portsmouth v/cre undoubtedly disappointing. Air. Barnaby has calculated that, with the engines developing 7000 horse-power, a speed of 17i knots an hour might bo realised; but tho fact remained that, while the engines indicated 600 over the contract power, tho full-power runs only gave a mean speed of 10*0 k'lots, the revolutions per minuto being 91. There were, however, grounds for thinking that tho comparative failure was due, not to tho form of hull, but to some defect In the machln-ry. The I Is was propelled by two four-Wadert screws, each 18}ffc. ii\ diameter, with a pitch of ISft., the joint dlic-ar<» being considerably greater In proportion to the engine power than is common In alngle-screw alii ’B, wfcjlo the surface of tho blades was also exceptionally Urge, (Jn the trial it became evident that the engine* were overweighted by tho'screw*, and that tho friction.and drag which were set up materially detracted from the effective power of tho. machinery. It was accordingly arranged, for experimental purposes only, to remove two of the four blades on each fan and to make a series of progressive trials in order bo see v/hat improvement would result from a reduction of tho blade-area and a consequent relief to the engines. According to an analysis which has been- made by Sir. \Y, 11, White, of the Admiralty, the highest power developed under the novel conditions was 43(59 horses, the corresponding speed 153 kuots, and the revolutions bO. With tho four-bladcd screws 16£ knots had required 6250 - horse - power. and 43C9 - horsepower would have sufficed for UJ knots only. It was not considered desirable to press the extemporised two-bladed screws by running at any higher speeds, nor by their form or pitch were they adapted for use as fcwo-bladcd propellers ; but enough had bceti done to show that the performance of tho ship could be greatly improved by a modification In the size of her fanj. .Tho .purpose of the trial last Wednesday was to practically test tho accuracy of tho deduction. Tho ship was In charge of Captain .Tones, and tho trial wai sup rlnfcended by Mr. Nathaniel Barnaby, Director of Naval Construction ; Air. J. Wright, the ihiglncer-in-Chief at the Admiralty ; Air. Icely/ of the Steam Reserve; Air. Duraton, of the Factory Department: and Air. George Thompson, the chief engineer of tho ship. Air. Fronde, juu., and Air. Brunei v/cro again in attendance for the purpose of taking electric diagrams of tho performances of tho engines, tho force of the wind, Ac. Tho ship was trimmed by ballast and coal to 16 feet 8 indies forward and 20 feet ,0 Inches aft, which was near about her load-line: and the new experimental fonr-bladed screws were 10 feet 3 Inches In diameter, . and had » pitch of 20 feet. While tho diameter had been reduced the pitch had been Increased, the ratio of screw disc *t6 area of midihip flection bong, thus much le?s than on tho original t-l*l The blades were smoothed to prevent friction and conical caps had been tapped into tho bosses over thf* nuts Which secure the screws to tho shafts, for tho i/uruoao of preventing tho v/ave which has been fouud to follow h Muif ending, wlwby the resistance

against which tho ship has to contend In passing through the water is augmented. The result of tho trial was In every respect more* than satisfactory * , Four fuP-power runs were made on the mile with the . following surprising results Steam at engines, 02 lbs.; vacuum/ 27 -inches; rc-v volutions, 9G starboard and 93 port; 7734’85 : speed of vcsael, 18 572 knots. IThe engines thus developed fully 700 horses more than the con-; ; tract, while the ship realised two knot* In excess of the- speed obtained from tho larger screws, and' fully a knot more 1 than tho Constructive Department anticipated to got out of her. - Four runs, at 10} knots gave 5132’1fi horse-power, with,Bo revolutions. Tills, as will have been seen, was tho utmost rfpeed realised at the original trial with 7500 horsc-power and 01 revolutions. Two runs at 12 knots gave 1837T4 horsepower, with 02 and 00 revolutions, and two runs fit 8 knots gave 607"25• horse-power, with 41 revolutions. The eng'nes were also turned as slowly as ppsaiblo with tho steam at only a little above the atmospheric pressure, when the following data were obtained: — Revolutions, 24 starboard and 19 port: vacuum, 28 inches: power indicated, starboard engines 127, port 59, making a total of ISO horses. There were scarcely .any vibrations noticed, although at tho previous trials thoshaking of the ship was excessive. Altogether the performances of the screws and tho ship were so satisfactory, that further experiments are superfluous, and similar propellers to those of the Iris will- bo fitted forthwith to the Mercuryi
