They displaced at standard load and at deep load.Whitley, p. 203 The ships had two Kampon geared steam turbines, each driving one propeller shaft, using steam provided by three Kampon water-tube boilers. The turbines were rated at a total of for a designed speed of . The main armament of the ''Yūgumo'' class consisted of six Type 3 guns in three twin-gun turrets, one superfiring pair aft and one turret forward of the superstructure. The guns were able to elevate up to 75° to increase their ability against aircraft, but their slow rate of fire, slow traversing speed, and the lack of any sort of high-angle fire-control system meant that they were virtually useless as anti-a ...

Propeller Shaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-19th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semirara Island
Semirara is an island in the Philippines located at in the Caluya archipelago which is situated south of Mindoro Island. It is under the jurisdiction of the town of Caluya of the province of Antique. It is a major site of coal mining in the Philippines. Other economic activities in the island include fishing, seashell gathering, and farming. History The island was declared a mineral reservation by President Manuel Quezon in 1940 through Proclamation No. 649. Semirara Mining and Power Corp. (SPMC) opened its first coal mine in the island in Unong in 1984 which operated until 2000 and the area's vegetation and lake restored years later. The company then opened several more mines including the Panian Pit which operated until in October 2016 shortly after its coal deposits depleted. SPMC also opened the Narra Pit and the Molave Pit in Semirara Island, both which started commercial operations in the same year. Administration Semirara Island is part of the municipality of Caluya of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

Coron Island
Coron is the third-largest island in the Calamian Islands in northern Palawan in the Philippines. The island is part of the larger municipality of the same name. It is about southwest of Manila and is known for several Japanese shipwrecks of World War II vintage. Because of its unique ecological features, the entire area is protected by several legal proclamations. The island and surrounding fishing grounds are part of the ancestral domain of the indigenous Tagbanwa people, officially designated such on June 5, 1998. Known as Calis among the Tagbanwas and Coronians, its tribal chieftain is Rodolfo Aguilar I. The island comprises two barangays of the municipality of Coron: Banuang Daan and Cabugao. Geography Partially between Busuanga and Culion islands, Coron Island faces the Sulu Sea and forms the eastern side of Coron Bay. It is about long from north to south, and at its widest point. Part of the North Palawan Block, Coron Island is distinguished by its Late Triassic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
