NZR G Class (1928)
The NZR G class was a type of Garratt locomotives used in New Zealand, later rebuilt as Pacific (locomotive), Pacific type locomotives. They were the only Garratt type steam locomotives ever used by the New Zealand Railways Department, New Zealand Railways (NZR). They were ordered to deal with traffic growth over the Grade (slope), 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. The locomotives lasted longer in rebuilt form as standard Pacific locomotives than they did as Garratts, but their numerous mechanical issues lead to their final withdrawal following a union ban on their use in 1956. Introduction About 1913, the General Manager E. H. Hiley considered the importing of ten articulated Garratt engines and ten Pacifics. With the success of the NZR AB class, AB class and NZR WAB c ...

Mercedes-Benz G-Class
The Mercedes-Benz G-Class, colloquially known as the G-Wagon or G-Wagen (as an abbreviation of Geländewagen), is a four-wheel drive luxury SUV manufactured by Magna Steyr (formerly Steyr-Daimler-Puch) in Graz, Styria, 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 was 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 introduced the second-generation W463 with heavily revised chassis, powertrai ...

Power Amplifier Classes
In electronics, power amplifier classes are letter symbols applied to different power amplifier types. The class gives a broad indication of an amplifier's efficiency, linearity and other characteristics. Broadly, as you go up the alphabet, the amplifiers become more efficient but less linear, and the reduced linearity is dealt with through other means. The first classes, A, AB, B, and C, are related to the time period that the active amplifier device is passing current, expressed as a fraction of the period of a signal waveform applied to the input. This metric is known as conduction angle (\theta). A class-A amplifier is conducting through the entire period of the signal (\theta=360°); class-B only for one-half the input period (\theta=180°), class-C for much less than half the input period (\theta 180°); each one of the two active elements conducts more than half of the time. Class-AB is widely considered a good compromise for amplifiers, since many types of input signal are ... [...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, main-sequence star (luminosity class V) of stellar classification, spectral type G. Such a star has about 0.9 to 1.1 solar masses and an effective temperature between about . Like other main-sequence stars, a G-type main-sequence star converts the Chemical element, element hydrogen to helium in its core by means of nuclear fusion. 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), Mass–energy equivalence, 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, and 51 Pegasi. Description Th ...

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
Airspace class is a category used to divide the sky into different zones, defined by both geographical boundaries and altitude levels. The International Civil Aviation Organization (ICAO) provides standardized airspace classifications that most countries follow. The classification dictates the level of control and services provided to aircraft operating within that airspace. However, nations may choose to implement only certain classes and modify the associated regulations and requirements to suit their needs. Additionally, countries can establish special use airspace (SUA) zones with supplementary regulations to address national security concerns or safety considerations. 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 r ...

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. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
