NORTHROP XB-35 YB-49 FLYING WING
Title: Northrop XB-35 and YB-49 Flying Wing
The Northrop Flying Wings were the brainchild of Jack Northrop, who conceived the “flying wing” as a means of reducing parasitic drag and eliminating structural weight not directly responsible for producing lift. In theory, the flying wing could carry a greater payload faster, farther, and cheaper than a conventional bomber.
In 1941 the USAAF issued a specification for a long-range bomber capable of carrying 10,000 lbs of bombs 10,000 nm. This contract, won by the Convair B-36 design, was extended to include the work Northrop was doing.
The first XB-35 flew in June 1946. The aircraft suffered from a large range of technical difficulties, but was already made obsolete by the jet engine. Three YB-35 aircraft were converted to jet power, two YB-49s with eight Allison J35 engines in the wing, and one YRB-49A with four engines in the wing and two in external pods. Two aircraft were lost in accidents, and the remaining prototype and all semi-completed airframes were scrapped.
This title contains the flight manual and maintenance manual for the XB-35, the parts catalog for the XB-35/YB-49 and two pilots handbooks for different variants of the YB-49. The files have been scanned from copies of the flight manuals.
