04.10.2020A wide-body aircraftalso known as a twin-aisle aircraftis an airliner with a fuselage wide enough to accommodate two passenger aisles with seven or more seats abreast. The largest wide-body aircraft are over 6 m 20 ft wide, and can accommodate up to eleven passengers abreast in high-density configurations. By comparison, a typical narrow-body airliner has a diameter of 3 to 4 m 10 to 13 ftwith a single aisle, [1] [5] and seats jambo jet planes model two and six people abreast.
Jambo jet planes model aircraft were originally designed for a combination of efficiency and passenger comfort and to increase the amount of cargo space. However, airlines quickly gave in to economic factors, and reduced the extra passenger space in order to maximize revenue jambo jet planes model profits. Wide-body aircraft are also used for the transport jambo jet planes model commercial freight and cargo [8] and other special uses, described further below.
The term jumbo jet usually refers to the largest wide-body airliners due to their very large size; examples include the Boeing the first wide-body and original "jumbo jet"Airbus A "superjumbo jet"and Boeing X "mini jumbo jet". Seven-abreast aircraft typically seat to passengers, eight-abreast jambo jet planes modelnine- and ten-abreast to By the end ofnearly 8, wide-body airplanes had been delivered sincepeaking at jambo jet planes model Following jambo jet planes model success of the Boeing and Douglas DC-8 in the late s and early s, airlines began seeking planws aircraft to meet the rising global demand for air travel.
Engineers were faced with many challenges as airlines demanded more passenger seats per aircraft, longer ranges and lower operating costs. Early jet aircraft such as the and DC-8 seated passengers along either side of a moxel aisle, with no more than six seats per row.
Larger aircraft would have to be longer, higher such as a double-deckor wider in order to accommodate a greater number of passenger seats. Engineers realized having two decks created difficulties in meeting emergency evacuation regulations with the technology available at that time. During the s, it was also believed that jambo jet planes model airliners would succeed larger, slower planes.
Thus, it was believed that most subsonic aircraft would become obsolete for passenger travel and would be eventually converted to freighters. As a result, airline manufacturers opted for a wider fuselage rather than a taller one theand eventually the DC and L By adding a second aisle, the wider aircraft could accommodate as many as 10 seats across, but could also be easily converted to a freighter and carry two eight-by-eight freight pallets abreast.
The engineers also opted for creating "stretched" versions of the DC-8 61, 62 and 63 modelsas well as longer versions of Boeing's B and C models and model ; and Douglas' DC-9, and modelsall of which were capable of accommodating more seats than their shorter predecessor versions. The wide-body age began in with the entry into service of the first wide-body airliner, the four-engined, partial double-deck Boeing The first wide-body twinjetthe Airbus Aentered service in This period came to be known as the "wide-body wars".
After the success of the jambo jet planes model wide-body aircraft, several subsequent designs came to market over the next two decades, including the Boeing andthe Airbus A and Aand the McDonnell Douglas MD In the "jumbo" category, the capacity of the Boeing was not surpassed until Octoberwhen the Airbus A entered commercial service with the nickname "Superjumbo".
The proposed Comac C and Planee may also share this new wide-body market. The production of the large Boeing and Airbus A four-engine, long-haul jets is coming to an end as airlines are now preferring the smaller, more efficient Aand twin-engine, long-range airliners.
Although wide-body aircraft have larger frontal areas and thus greater form drag than narrow-body aircraft of similar capacity, they have several advantages over their narrow-body counterparts, such as:. British and Russian designers had proposed wide-body aircraft similar in configuration to the Vickers VC10 and Douglas DC-9but with a wide-body fuselage.
The British Three-Eleven project never left the drawing board, while the Russian Il wide-body proposal eventually gave way to a more conventional wing-mounted engine design, most likely due to the inefficiencies of mounting such large engines on the mdoel fuselage. As jet engine power and reliability have increased over the last decades, most of the wide-body aircraft built today have only two engines.
A twinjet design is more fuel-efficient than a trijet or quadjet of similar size. The trijet design was dismissed due to higher maintenance and fuel costs compared to a twinjet. The upcoming Boeing X -9 twinjet is approaching the capacity of the earlier Boeing Complete GE90 engines can only be ferried by outsize cargo aircraft such as the Antonov Anpresenting logistics problems if a is stranded in a place due to emergency diversions without the proper spare parts.
If planse fan is removed from the core, then the engines may be shipped on a Boeing Freighter. The t 1, lb maximum takeoff weight of the Airbus A would not have been possible without the engine technology developed for the Boeing such as contra-rotating spools.
The Trent is designed to fit jambo jet planes model a Boeing F freighter for easier transport by air cargo. The interiors of aircraft, known King Air Jet Planes Model as the aircraft cabinhave been undergoing evolution since the first passenger aircraft. Today, between one and four jambo jet planes model of travel are available on wide-body aircraft. Bar and lounge areas which were once installed on wide-body aircraft have mostly disappeared, but a few have returned in first class or business class on the Airbus A[29] Boeing ER jambo jet planes model, [30] and on the Airbus A Depending on how the airline configures the aircraft, net size and seat pitch of the airline seats will vary significantly.
Due to current economic pressures jambo jet planes model the airline industry, high seating densities hambo the economy class cabin hambo likely to continue. In some of the largest single-deck wide-body aircraft, such as the Boeingthe extra space above the cabin is used for crew rest areas and galley storage.
Modell comparison of interior cabin widths and economy class seating layouts is shown below under wide-body specifications. Further information can be found under external links.
The economy class cabin of an Airbus A Cathay Pacific 's First Class cabin on board jambo jet planes model Boeing Aircraft are categorized by ICAO according to the wake turbulence they produce.
Because wake turbulence is generally related to the weight of an aircraft, these categories are based Jambo Jet Planes Youtube on one of four weight categories: jambo jet planes model light, medium, heavy, and super.
Due to their weight, all current wide-body aircraft are categorized as " heavy ", or jambo jet planes model the case of the A in U. The wake-turbulence category also is used to guide the separation of aircraft. In some countries, such as the United Statesit is a requirement to suffix the aircraft's call sign with the word heavy or super when communicating with air traffic control in certain areas.
Wide-body aircraft are used in science, research, and the military. Some wide-body planrs are used as flying command posts by the military like the Jambo jet planes model Il [ citation needed ] or the Boeing E-4while the Boeing Jsmbo is used for Airborne Early Warning and Control.
New jambo jet planes model weapons are tested aboard wide-bodies, as in the laser weapons testing on the Boeing YAL Other wide-body aircraft are used as flying research stations, such as the joint German—U. Airbus A, [39] Airbus A, [40] and Boeing [41] four-engine wide-body aircraft are used to test new generations of aircraft engines in flight.
A few aircraft have also been converted for aerial firefightingsuch met the DC -based [42] Tanker and the -based Evergreen Supertanker. Some wide-body aircraft are used as VIP transport. Canada uses the Airbus Awhile Russia use the Jambo Jet Planes Kenya 5g Ilyushin Ilto transport those holding the highest offices.
Germany replaced their Jambo jet planes model A with an Airbus A in spring Some wide-body aircraft plqnes been modified to enable transport of especially large cargo. Two specially modified Boeing s were used to transport the U. Space Shuttlewhile the Antonov An was initially built to carry the Buran. From Wikipedia, the free encyclopedia.
