Blended Wing Body – A potential new aircraft design
翼胴合體-一種潛在的新飛機設計

NASA and its industry partners are investigating a blended wing aircraft concept for potential use as a future air transport for both civilian and military applications.
美國太空總署與其工業夥伴正在研究翼胴合體的概念做為未來民用與軍用飛機的潛在用途

The concept is called the blended wing body (BWB).
這個概念稱作翼胴合體

The BWB is a hybrid shape that resembles a flying wing, but also incorporates features from conventional transport aircraft.
這個翼胴合體是種混合外型整體來說像是個飛行翼,但是也融入了傳統飛機的特色.

This combination offers several advantages over conventional tube-and wing airframes.
這樣的結合提供了一些超越傳統管狀機體的優點.

The BWB airframe merges efficient high-lift wings with a wide airfoil-shaped body, allowing the entire aircraft to generate lift and minimize drag.
翼胴合體的機身結合了高效率的升力機翼與機身結合在一起,讓整個機身都可以產生升力把阻力降到最低.

This shape helps to increase fuel economy and creates larger payload (cargo or passenger) areas in the center body portion of the aircraft.
這樣的構型提昇了燃油效率,和在機體中央創造了大型的內部載人或載貨空間.

The basic concept for a blended wing body was first developed decades ago and variations of it have been used in the famous B-2 bomber (a blended wing) and the lesser-known YB-49 (a pure flying wing from the 1940’s).
這翼胴合體的基本的概念首次開發於數十年之前,著名的B-2(翼胴合體)轟炸機,還有鮮為人知的YB-49(純飛翼式機體1940)兩者都是.

Like the B-2, the BWB design uses composite materials that are stronger and lighter than conventional metal construction.
就像是B-2,翼胴合體的設計使用複合材料較傳統金屬材料結構強度更佳且輕.

The BWB also has several control surfaces on the trailing edge, like the B-2, instead of the conventional tail assembly.
翼胴合體有些飛行控制翼面在機翼後端就跟B-2一樣,是用來取代傳統的控制翼面的.

The BWB shape allows unique interior designs.
翼胴合體外型有著獨一無二的內部設計

Cargo can be loaded or passengers can board from the front or rear of the aircraft.
貨物或是乘客可以從前面或是後面上飛機

The cargo or passenger area is distributed across the wide fuselage, providing a large usable volume.
貨物或是乘客區是分佈在寬廣的機身裡面,提供了大型且可用的容積.

For passengers in the interior of the craft, real-time video at every seat would take the place of window seats.
對坐在飛機內的乘客來說,每張座椅都會由攝影機擷取即時的窗外景色,一如坐在窗邊的位置一樣.
