2020年7月27日 · In September of 1996, Boeing needed a new big aircraft to compete with Airbus' new A3XX project (revealed to be the A380 half a decade later). Their new design? A super jumbo called the Boeing 747-700X. What happened to this legendary aircraft? Let's explore. What was the mystery 747-700X? Photo: Getty Images.

2023年1月5日 · The 747X was a project concept of a bigger version of the 747. It would use a new wing (derived from technology created for the Boeing 777 series) and use the latest engines that would allow a bigger, heavier aircraft to take off. Boeing actually tried twice to design an aircraft designated the 747X.

波音747是一款半雙層四引擎飛機，可用于載客、載貨、軍事或其它用途，例如作為美國總統 指揮專機 和 空軍司令部。 747上層甲板的設計令它的貨機型號能夠在機首加裝貨艙門，客機型號則可以增加額外座位，使得三級座艙設計（即是分為 經濟， 商務 和 頭等 艙）的載客量達到416人，而雙級艙設計的載客量則高達524人。 747這種大型客機在1969年橫空出世，令民航載客量顯著的增加，並降低了機票成本與價格，普羅大眾環遊世界也成為了可能，對於世界產生了巨大的影響 …

The 747-600X concept featured a greater stretch to 279 ft (85 m) with seating for 548 passengers, a range of up to 7,700 nmi (8,900 mi, 14,300 km), and a gross weight of 1.2 Mlb (540 Mg). A third study concept, the 747-700X, would have combined the wing of the 747-600X with a widened fuselage, allowing it to carry 650 passengers over the same ...

A third study concept, the 747-700X, would have combined the wing of the 747-600X with a widened fuselage, allowing it to carry 650 passengers over the same range as a 747-400. The cost of the changes from previous 747 models, in particular the new wing for the 747-500X and -600X, was estimated to be more than $5 billion.

2022年8月12日 · A third study concept, the 747-700X, would have combined the wing of the 747-600X with a widened fuselage, allowing it to carry 650 passengers over the same range as a 747-400. The cost of the changes from previous 747 models, in particular the new wing for the 747-500X and -600X, was estimated to be more than $5 billion.

2023年2月16日 · The mega-stretch: 747-700X. In the 1990s Boeing sought to seriously compete with what seemed like an upcoming wave of superjumbos, spearheaded by the Airbus A380. After considering and rejecting the NLA (New Large Aircraft) proposal and some double-decker 747 modifications, Boeing settled on stretching and upgrading what it already had.

2021年2月18日 · The 747-600X concept featured a greater stretch to 279 ft. (85 m) with seats for 548 passengers, a range of up to 7,700 nmi (8,900 mi, 14,300 km), and a gross weight of 1.2 Mlb (540 tons).

2023年11月2日 · Boeing’s work and development surrounding future variants in the Boeing 747 family wouldn’t stop at just the 747-500X, -600X and -700X, with a further round of concept studies unveiled. The more refined 747X and 747X Stretch were in direct response towards the growing anticipation of Airbus’ widebody study, the A3XX.
