NZR G Class (1928)
The NZR G class was a type of Garratt steam locomotive used in New Zealand, the only such Garratt type steam locomotives ever used by the New Zealand Railways (NZR). They were ordered to deal with traffic growth over the heavy gradients of the North Island Main Trunk (NIMT) and to do away with the use of banking engines on steep grades. They were one of the few Garratt designs to employ six cylinders. A mechanical stoker was used to feed coal into the locomotive. Introduction About 1913, General Manager E H Hiley considered the importing of 10 articulated Garratt engines and 10 Pacifics; however, with the success of the AB class and WAB class Pacifics no more was heard of Garratts. Then with the retirement in 1925 of the Chief Mechanical Engineer E E Gillon his successor G S Lynde invited Beyer, Peacock & Company of England to suggest a suitable Garrett for the NIMT, and they were then asked to quote for engines with either four or six cylinders. But the three six-cylinder e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
G-class Frigate
The G class (Turkish: ''Gabya sınıfı fırkateyn(ler)'') is one of the frigate classes of the Turkish Navy. They are extensively modernized versions of ex- guided-missile frigates of the US Navy, mainly designed for air defense with a weapons configuration that is optimized for general warfare. Modernization The G-class frigates have undergone a major modernization program which included the retrofitting of a Turkish digital combat management system named GENESIS (''Gemi Entegre Savaş İdare Sistemi''). The system was designed and implemented jointly by the Turkish Navy and HAVELSAN, a Turkish electronic hardware systems and software company. The first GENESIS upgraded ship was delivered in 2007, and the last delivery is scheduled for 2011. The GENESIS advanced combat management system includes the following characteristics and abilities: * A modern and reliable system * High performance * Open architecture * Capacity of tracking more than 1,000 tactical targets * Modern digit ...

Mercedes-Benz G-Class
The Mercedes-Benz G-Class, sometimes colloquially called the G-Wagen (as an abbreviation of Geländewagen) is a four-wheel drive automobile manufactured by Magna Steyr (formerly Steyr-Daimler-Puch) in Austria and sold by Mercedes-Benz. Originally developed as a military jeep, military off-roader, later more luxury car, luxurious models were added to the line. In certain markets, it has been sold under the Puch name as Puch G until 2000. The G-Wagen is characterised by its boxy styling and body-on-frame construction. It uses three fully locking differentials, one of the few passenger car vehicles to have such a feature. Despite the introduction of an intended replacement, the unibody SUV Mercedes-Benz GL-Class in 2006, the G-Class is still in production and is one of the longest-produced vehicles in Daimler's history, with a span of years. Only the Unimog surpasses it. In 2018, Mercedes-Benz launched a technically new second generation, still with only minor design changes. The ...

Electronic Amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a Signal (information theory), signal (a time-varying voltage or Electric current, current). It may increase the power (physics), power significantly, or its main effect may be to boost the voltage or current (power amplifier, power, voltage or current amplifier). It is a two-port network, two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a greater amplitude signal at its output. The ratio of output to input voltage, current, or power is termed gain (electronics), gain (voltage, current, or power gain). An amplifier, by definition has gain greater than unity (if the gain is less than unity, the device is an attenuator (electronics), attenuator). An amplifier can either be a separate piece of equipment or an electrical circuit contained within another device. Amp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
G-type Main-sequence Star
A G-type main-sequence star (Spectral type: G-V), also often, and imprecisely called a yellow dwarf, or G star, is a main-sequence star (luminosity class V) of spectral type G. Such a star has about 0.9 to 1.1 solar masses and an effective temperature between about 5,300 and 6,000 K. Like other main-sequence stars, a G-type main-sequence star is converting the element hydrogen to helium in its core by means of nuclear fusion, but can also fuse helium when hydrogen runs out. The Sun, the star in the center of the Solar System to which the Earth is gravitationally bound, is an example of a G-type main-sequence star (G2V type). Each second, the Sun fuses approximately 600 million tons of hydrogen into helium in a process known as the proton–proton chain (4 hydrogens form 1 helium), converting about 4 million tons of matter to energy. Besides the Sun, other well-known examples of G-type main-sequence stars include Alpha Centauri, Tau Ceti, Capella and 51 Pegasi. The term ''yel ...

G-class Blimp
The ''G''-Class Blimps were a series of non-rigid airships (blimps) used by the United States Navy. In 1935, instead of developing a new design airship, the Navy purchased the Goodyear Blimp ''Defender'' for use as a trainer and utility airship assigning it the designator ''G-1''. ''Defender'' was built by the Goodyear Aircraft Company of Akron, Ohio and was the largest blimp in the company’s fleet of airships that were used for advertising and as passenger airships. Goodyear built additional ''G''-class airships for the Navy during World War II to support training needs. Operational history After purchase on September 23, 1935, ''G-1'' was in constant use until it was lost in a mid-air collision on 8 June 1942 with another blimp, the ''L-2''. The two blimps were conducting experimental visual and photographic observations during night flight. Although twelve people were killed in the crash, ''G-1'' had demonstrated her capabilities as a trainer and utility blimp. As the Nav ...

Airspace Class
The world's navigable airspace is divided into three-dimensional segments, each of which is assigned to a specific class. Most nations adhere to the classification specified by the International Civil Aviation Organization (ICAO) and described below, though they might use only some of the classes defined below, and significantly alter the exact rules and requirements. Similarly, individual nations may also designate special use airspace (SUA) with further rules for reasons of national security or safety. Abbreviations used in this article ICAO definitions On March 12, 1990, ICAO adopted the current airspace classification scheme. The classes are fundamentally defined in terms of flight rules and interactions between aircraft and air traffic control (ATC). Generally speaking, the ICAO airspaces allocate the responsibility for avoiding other aircraft, namely either to ATC (if separation is provided) or to the aircraft commander (if not). Some key concepts are: * Separation: Mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OOCL G-class Container Ship
The G class is a series of container ships built for OOCL. With a maximum theoretical capacity of 21,413 TEU they were the largest container ships in the world when they were built and the first ships with a capacity larger than 21,000 TEU. They took the title of largest container ships from ''Madrid Maersk'' (20,568 TEU). They have since been surpassed by other ships like the (23,756 TEU) and the (23,964 TEU). The ships have 24 container bays. Containers can be placed 23 wide on deck and 21 wide below deck. History In April 2015 Samsung Heavy Industries announced it had received an order from OOCL to build six container ships of 21,100 TEU for a total cost of 950 million USD. The first ship, the ''OOCL Hong Kong'', was christened on 12 May 2017. On 18 October 2017 the ''OOCL Japan'' suffered a mechanical failure while traversing the Suez Canal, causing the ship to run aground. She was quickly pulled free by tugs and was able to continue her maiden voyage to Europe. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

G-class Landing Craft
The G class, or "G-boat" also known as the Marine Alutech Watercat M8 landing craft ( fi, G-vene, sv, Gruppbåt) is a type of vessel in use by the Finnish Navy and the Swedish Navy. The G-boat was originally designed for the Swedish Navy which ordered about 100 of them. It is primarily used for amphibious landings by, and transportation of, marines. It has a very low draught (approximately 20 cm) at high speeds which makes it ideal for amphibious assault even in shallow waters. It has a cargo capacity of 8 men or one metric ton.

Tasmanian Government Railways G Class
The Tasmanian Government Railways G class was a class of steam locomotives operated by the Tasmanian Government Railways. History In 1896, the Tasmanian Government Railways purchased two steam locomotives from Sharp, Stewart and Company, Glasgow to operate the North East Dundas Tramway. Shortly after entering service, G1 was destroyed on 17 May 1897 after the boiler exploded. The crew were killed and the boiler flung 30 metres into the air landing 230 metres away. A replacement arrived in 1900, assuming G1's identity. After the railway closed, both were sold to the Isis Sugar Mill in Cordalba, Queensland and converted to tender locomotives'."Steam Locomotives of the Tasmanian Government Railways and its Constituents" ''Australian Railway History'' issue 917 March 2014 page 18 G1 ended up in a Childers service station, but has since disappeared, while G2 was sold for use at a planned Sydney theme park, but illegally cut up at St Marys in 1991.
