Northrop YB-49 FLYING WING Pilot Manual Airplane BOOK !

Visionary designer Jack Northrop built a series of experimental “flying wing” aircraft both before and during WWII. One of the most radical designs of the post-war era, the propeller-driven YB-35 bomber’s all-wing design minimized drag and promised maximum payload capacity and terrific endurance. The YB-49, a turbojet powered variant built on the YB-35 airframe, forever altered aviation history and inspired the design of the B-2 Spirit stealth bomber.

Originally printed by Northrop Aircraft in 1948, the YB-49 Flying Wing Pilot's Flight Operating Manual taught pilots everything they needed to know before entering the cockpit. Originally classified “Restricted”, the manual was declassified long ago and is reprinted in book form for the first time in nearly 60 years!

This affordable facsimile has been reformatted, and color images appear as black and white. Care has been taken however to preserve the integrity of the text. It even includes racy, and definitely NOT politically correct, reproductions of the manual's original instructional cartoons!

More on the YB-49 Flying Wing

The Northrop YB-49 was a prototype jet-powered flying

With the B-35 program seriously behind schedule by 1944, and the end of the piston-engined warplane in sight, the production contract for the type was cancelled in May. Nevertheless, the design was still sufficiently interesting to the Air Force that work on the pre-production aircraft was ordered to continue for testing purposes. Amongst the aircraft to be completed were two that the Air Force required to be fitted with jet propulsion.

The first aircraft flew on October 1, 1947 and immediately proved more promising than its piston-engined counterpart. The YB-49 set both an unofficial endurance record of staying continually above 40,000 ft (12,200 m) for six hours, and a trans-continental speed record, flying from Muroc Air Force Base in California to Andrews Air Force Base in Washington, DC in 4 hours 20 minutes. The program nevertheless experienced a number of serious setbacks, not least of which was a disastrous crash of one of the prototypes, killing its pilot, Capt Glen Edwards (after whom Edwards Air Force Base is named) and all crew. The cause was never fully explained, but appears to have been a serious structural failure.

In September 1948, the Air Force ordered the type into production as the RB-49A reconnaissance aircraft, with Convair to undertake the mass-production. By January, however, this order was cancelled, due in part to a particularly damning report delivered by Air Force test pilot Maj Robert Cardenas in November which painted the aircraft as seriously unstable.

Aerodynamics experts have recently proposed the theory that the instability of the YB-49 was due to the fact that it was adapted from the YB-35 without taking into account the need to redesign the wing completely after the removal of the propellers. They note that the propeller equipped YB-35 did not have instability problems, since the spinning propellers acted as discs in the airflow and gave an important stabilizing surface, which was absent with the jet engines.

Testing of the one remaining YB-35 prototype still continued through most of 1949, with the aircraft demonstrating many problems as a bombing platform and also suffering a major engine-bay fire. On March 15, 1950, the program was cancelled completely, and co-incidentally, the prototype suffered an accident while taxiing and was...
