HMS Ashanti (F117)
HMS ''Ashanti'' was a of the Royal Navy. She was named after the Ashanti people, an ethnic group located in Ghana. The frigate was sunk as a target in 1988. ''Ashanti'' was built by Yarrow, of Scotstoun, at a cost of £5,315,000 and was the first commissioned Royal Navy warship to be equipped with combined steam and gas (COSAG) engines. She was launched on 9 March 1959 and commissioned on 23 November 1961. Operational Service In 1962 malicious damage was reported aboard ''Ashanti''. ''Ashanti'' deployed to the Caribbean for trials in 1962. There, in early October, the ship suffered a failure in her COSAG engines, forcing the frigate's return to Britain. Subsequent tests discovered that the COSAG's machinery was defective, which caused blade fracturing in the gas turbine. Hull strengthening also found to be required ''Ashanti'' was also used to trial the Westland Wasp helicopter, prior to its introduction to active service in 1964. The frigate conducted operations in the Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Westland Wasp
The Westland Wasp is a small 1960s British turbine powered, shipboard anti-submarine helicopter. Produced by Westland Helicopters, it came from the same P.531 programme as the British Army Westland Scout, and is based on the earlier piston-engined Saunders-Roe Skeeter. It fulfilled the requirement of the Royal Navy for a helicopter small enough to land on the deck of a frigate and carry a useful load of two homing torpedoes. The Wasp sank one ship in combat, seriously damaging the ARA ''Santa Fe'' submarine in 1982 during the Falklands war. Design and development The increasing speed and attack range of the submarine threat, and the increased range at which this threat could be detected led to a Royal Navy requirement for a "Manned Torpedo-Carrying Helicopter" (MATCH). Contemporary shipboard weapons did not have the necessary range, therefore MATCH was in essence a stand-off weapon with the helicopter carrying the torpedo or other weapon to the target and being instructed ...

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

Sea Trial
A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a " shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, they are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combined Steam And Gas
Combined steam and gas (COSAG) is a propulsion system for ships using a combination of steam turbines and gas turbines to power the shafts. A gearbox and clutches enable either of the engines or both of them together to drive the shaft. It has the advantage of the cruising efficiency and reliability of steam and the rapid acceleration and start-up time of gas. This system was mainly used on first-generation gas-turbine ships such as the Royal Navy The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against Fr ...'s and .

Scotstoun
Scotstoun ( gd, Baile an Sgotaich) is an area of Glasgow, Scotland, west of Glasgow City Centre. It is bounded by Garscadden and Yoker to the west, Victoria Park, Jordanhill and Whiteinch to the east, Jordanhill to the north and the River Clyde (and Braehead beyond) to the south. At the heart of Scotstoun lies Scotstounhill, an enclave of late Victorian and post-war housing centred on Scotstounhill railway station. Scotstoun (along with the Govan shipyard) is home to BAE Systems Surface Ships (formerly Yarrow Shipbuilders), and to the Glasgow Warriors rugby team. History Scotstoun was until the early 1860s the site of the Oswald family estate, which was centred on Scotstoun House. By 1861 the westward expansion of the Clyde shipbuilding yards had reached Scotstoun with the opening of the Charles Connell and Company shipyard in 1861 and the new Yarrow Shipbuilders yard in 1906. This led to the break-up of the estate, as portions were sold off for housing, to create Victoria Park a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ashanti People
The Asante, also known as Ashanti () are part of the Akan ethnic group and are native to the Ashanti Region of modern-day Ghana. Asantes are the last group to emerge out of the various Akan civilisations. Twi is spoken by over nine million Asante people as a first or second language. The wealthy, gold-rich Asante people developed the large and influential Ashanti Empire, along the Lake Volta and Gulf of Guinea. The empire was founded in 1670, and the capital Kumase was founded in 1680 by Asantehene (emperor) Osei Kofi Tutu I on the advice of Okomfo Anokye, his premier. Sited at the crossroads of the Trans-Saharan trade, the Kumase megacity's strategic location contributed significantly to its growing wealth. Over the duration of the Kumase metropolis' existence, a number of peculiar factors have combined to transform the Kumase metropolis into a financial centre and political capital. The main causal factors included the unquestioning loyalty to the Asante rulers and the Kum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
