Collection Item Summary:

In 1945 Curtiss-Wright received a contract from the Army Air Forces for the XT35 turboprop engine, and Boeing was awarded a study contract for a long-range heavy bomber designated XB-52. Boeing initially proposed a straight-wing bomber powered by six Wright T35s, and then later revised the design to incorporate only four-more powerful-T35 engines.

Curtiss-Wright delivered six XT35-W-1 engines in late 1948. One was test flown in the nose of a Boeing EB-17G bomber and proved more powerful than the bomber's combined four standard reciprocating engines. However, the Air Force dropped the straight-wing, turboprop bomber design and decided instead to produce the now famous, swept-wing B-52 powered by Pratt & Whitney J57 turbojet engines. With no applications found for the XT35, and it never qualified for military application.
