Abstract
THE eleventh Thomas Hawksley lecture was read before the Institution of Mechanical Engineers on Friday. November 7, by Engineer Vice-Admiral Sir George G. Goodwin, and dealt with the development of marine-propelling machinery. Whilst naval conditions impose restrictions on the design of machinery, both warships and vessels of the mercantile marine must possess the qualities in their machinery of reliability, endurance, durability, and economy, each in high degree. The best economical performances are generally obtained in the merchant service, where machinery is designed for economical running at steady speed. In warships, economy at full power is necessary in order to keep down the weight of the boiler installation; most of the steaming is done at powers so low as one-tenth, or less of full power, and economy at these low powers is also of great importance. Both desires cannot be met completely, and a compromise is arranged.
