| Title | Watts, Sir Philip: certificate of election to the Royal Society |
| Citation | Naval Architect and Director of the War-Shipbuilding Department of Sir W G Armstrong, Whitworth and Co. Distinguished for his knowledge of the science and pratice of Naval Architecture. Responsible designer of a considerable number of the swiftest and most powerful war-ships. Has done much original scientific and experimental work in connection with investigations of the stability of ships and floating bodies; the oscillations of ships in still water and amonst waves; the propulsion and manoeuvring powers of ships. Was appointed by the Admiralty and acted for some years as assistant to the late Mr W Froude, FRS, on the analytical and experimental work carried on by that investigator. In that capacity took part in the device and application of the progress of 'graphic integration' by which the oscillations of ships can be approximately determined under assumed conditions of wave motion, including the effect of fluid resistance. Has independently proposed a method of reducing the rolling of ships at sea, by the introduction of free water into a suitably formed chamber. This plan was adopted by the Admiralty for several important ships, after mathematical and experimental demonstration of its efficiency. Was entrusted with the experimental investigation of the turning powers of HMS 'Thunderer' made in connection with the work of the 'Inflexible' Committee Devised and applied methods for determining exactlythe pathtraversed by the C G of the ship, the rate of acquisition of angular velocity, the angle of heel and other phenomena incidental to turning under the action of the rubber. This investigation led to subsequent modifications in the under-water form of ships, tendering to increase their handiness. Is author of the following papers printed in the Transactions of the Institute of Naval Architects: - 'On a Method of Reducing the Rolling of Ships at Sea' (1883); 'The Use of Water Chambers for Reducing the Rolling of Ships at Sea' (1885); 'The Italian Cruiser 'Piemonte' (1889); 'The Steering Qualities of the 'Yashima'' (1898); 'Elswick Cruisers Built during the last Ten Years' (1899). |
