[原创]波音公司网站关于波音747的简介

在20世纪60年代后期，将近50，000的波音员工隶属于一个令人难以置信的团队。那里有建筑工人，机械师，工程师，文书与管理人员，他们通过在不到16个月的时间里建造世界上最大的民用飞机－－波音747创造了民用航空历史。
  开发巨型的747飞机的动机源自于降低飞行票价，应对民用航空运输的爆炸式发展和日益拥挤的天空。另外，波音已经开发了这种飞机的设计理念和技术，因为公司将其用于竞争巨型军用运输机－－C-5A的合同，但失败了。
  747飞机在尺寸上的确具有里程碑的意义。这种巨大的飞机需要在华盛顿州埃弗雷特的一个2,000,000立方英尺的装配车间生产，这是世界上最大的建筑（就体积而言）。最初的747飞机的机身有225英尺长，尾翼相当于六层楼那么高。加压后，它可以承载一吨的空气。货舱可容纳3,400件行李，并可在7分钟内卸载完毕。机翼总面积比一个篮球场还大。而且，全部的全球导航系统比一台现代便携式电脑还轻。
  飞行员在波音的训练学校里准备747的飞行。驾驶如此巨大的飞机的经验通过一种名叫“威德尔”的装置获得的，它是以公司的首席试飞员，杰克 威德尔，命名的。飞行员坐在一个设置在一辆移动的卡车上，有三层楼高的747飞行平台的模拟器上。飞行员从这种高度上通过无线电指挥他下面的卡车司机来学习如何驾驶。
  后来国家航空航天局改装了两架波音747-100型飞机作为航天飞机轨道器载机。下一个型号，747-200型，载客将近440人，航程大约5,600海里。1990年，两架747-200B型飞机作为“空军一号”服役，用来替换服役将近30年的总统专机VC-137（波音707）。
  波音747-300延长了上层机舱以运载比200型更多的乘客。波音747-400首飞于1988年。翼展达212英尺，并且有6英尺高的翼稍小翼，用来作短途飞行。
  延程型的波音747-400型飞机（即747-400ER），开始于2,000年下半年。747-400ER，首飞于2,002年7月31日，适合于客货双重用途，航程达到了8,826海里。它综合了加固的400货运型的机翼，加固的机身和起落架，以及一个安装在前货舱的辅助油箱，并且可选择安装第二个。当747-400ER的长程功能不需要时，运营者可以卸除油箱，为货物释放多余的空间。

747

During the late 1960s, some 50,000 Boeing people belonged to a group called "The Incredibles." These were the construction workers, mechanics, engineers, secretaries and administrators who made aviation history by building the 747 — the largest civilian airplane in the world — in less than 16 months.
The incentive for creating the giant 747 came from reductions in air fares, an explosion in air-passenger traffic and increasingly crowded skies. In addition, Boeing had already developed the design concepts and technology of such an airplane because the company had bid on, but lost, the contract for a gigantic military transport, the C-5A.
The 747’s final design was offered in three configurations: all passenger, all cargo and a convertible passenger/freighter model. The freighter and convertible models loaded 8- by 8-foot cargo containers through the huge hinged nose.
The 747 was truly monumental in size. The massive airplane required construction of the 200-million-cubic-foot 747 assembly plant in Everett, Wash., the world’s largest building (by volume). The fuselage of the original 747 was 225 feet long; the tail as tall as a six-story building. Pressurized, it carried a ton of air. The cargo hold had room for 3,400 pieces of baggage and could be unloaded in seven minutes. The total wing area was larger than a basketball court. Yet, the entire global navigation system weighed less than a modern laptop computer.
Pilots prepared for the 747 at Boeing training school. The experience of taxiing such a large plane was acquired in a contraption called "Waddell’s Wagon," named after Jack Waddell, the company’s chief test pilot. The pilot sat in a mockup of the 747 flight deck built atop three-story-high stilts on a moving truck. The pilot learned how to maneuver from such a height by directing the truck driver below him by radio.
The National Aeronautics and Space Administration later modified two 747-100s into Shuttle Carrier Aircraft. The next version, the 747-200, holds approximately 440 passengers and has a range of about 5,600 nautical miles. In 1990, two 747-200Bs were modified to serve as Air Force One and replaced the VC-137s (707s) that served as the presidential airplane for nearly 30 years.
The 747-300 has an extended upper deck and carries even more passengers than the -200. The 747-400 rolled out in 1988. Its wingspan is 212 feet, and it has 6-foot-high "winglets" on the wing tips. The 747-400 also is produced as a freighter, as a combination freighter and passenger model, and as a special domestic version, without the winglets, for shorter-range flights.
The longer-range 747-400 airplanes (also known as 747-400ERs), were launched in late 2000. The 747-400ER, which first flew July 31, 2002, is available in both passenger and freighter versions and has a range of 8,826 miles. It incorporates the strengthened -400 Freighter wing, strengthened body and landing gear, and an auxiliary fuel tank in the forward cargo-hold, with an option for a second tank. When the 747-400ER's full-range capability is not needed, operators can remove the tank (or tanks), freeing up additional space for cargo.
