Martin XB-48 prototype taxiing, showing spaces between engines for cooling, tandem main gear, and nacelle outriggers The Martin XB-48 was an American medium jet bomber developed in the mid-1940s. It competed with the Boeing B-47 Stratojet , which proved to be a superior design, and was largely considered as a backup plan in case the B-47 ran ...
The Martin XB-51 was an American trijet ground-attack aircraft. It was designed in 1945 and made its maiden flight in 1949. It was originally designed as a bomber for the United States Army Air Forces under specification V-8237-1 and was designated XA-45. The "A" ground-attack classification was eliminated the next year, and the XB-51 ...
The XB-16 was designed to meet the United States Army Air Corps (USAAC) request for a bomber that could carry 2,500 lb (1,100 kg) of bombs 5,000 mi (8,000 km; 4,300 nmi). The XB-16 (Model 145A) was to use four Allison V-1710 liquid-cooled reciprocating V-engines ; contemporary American aircraft used air-cooled radial engines .
The Boeing X-48 is an American experimental unmanned aerial vehicle (UAV) built to investigate the characteristics of blended wing body (BWB) aircraft. Boeing designed the X-48 and two examples were built by Cranfield Aerospace in the UK. Boeing began flight testing the X-48B version for NASA in 2007. The X-48B was later modified into the X-48C ...
The Convair XB-46 was a single example of an experimental medium jet bomber which was developed in the mid-1940s but which never saw production or active duty. It competed with similar designs, the North American XB-45 and Martin XB-48, all of which saw little use after the successful development of the Boeing XB-47.
The Douglas XB-42 Mixmaster is an experimental American bomber aircraft, designed for a high top speed.The unconventional approach was to mount the two engines within the fuselage driving a pair of contra-rotating propellers mounted at the tail in a pusher configuration, leaving the wing and fuselage clean and free of drag-inducing protrusions.
XB-26H—This test aircraft for tandem landing gear was nicknamed the "Middle River Stump Jumper" from its "bicycle" gear configuration, to see if it could be used on the Martin XB-48. [49] (One converted) JM-1P—A small number of JM-1s were converted into photo-reconnaissance aircraft for the US Navy. [44] Marauder I
This new configuration was designated the XB-1B. Three other similar aircraft designs were requested by the Army Air Corps around the same time which competed against the XB-1 for the contract. Of these three (the XB-2 Condor, the Sikorsky S-37 and the Fokker XLB-2), the Curtiss model eventually won, and only a single XB-1 was ever produced.
