Summary
| Description |
English: Northrop YB-49 Flying wing, a heavy bomber prototype Cropped version of Image:YB49-1 300.jpg Northrop YB-49 flying wing. The YB-49 was the jet-propelled variant of the company's XB-35 bomber. Eight Allison J35 engines, each delivering 3,750 pounds of thrust, gave the flying wing a top speed of 510 mph, or more than 100 mph faster than its prop-driven predecessor. Flight testing revealed stability problems which could not be corrected with existing technology. The second aircraft crashed on June 5, 1948, killing its five-man crew. Edwards AFB was subsequently named for one of its crew members, Capt. Glen W. Edwards. |
