14-615: A different tailfin . Since the Continental engine was not available at rollout, the prototypes flew with Allison V-1710-47 engines. In 1942, the XP-39E was redesignated P-76. Although 4,000 aircraft were initially ordered, the order was cancelled to permit the Bell factory to manufacture B-29 Superfortress bomber aircraft under license from Boeing . Many of the lessons learned in the P-76 were implemented in
21-518: A more powerful engine in lieu of the V-1710. Its origins lie in the 1941 project to equip three P-39D (41-19501, 41-19502 and 42-7164) with the Continental V-1430 -1 liquid-cooled supercharged engine. The resultant XP-39E had a symmetrical airfoil wing with square wingtips, an elongated fuselage to accommodate the larger engine, and revised air intakes and radiators . The three prototypes each had
28-454: A new Allison V-1710-E9 was also underway. This version, which had the military designation of V-1710-47, used a two-stage mechanical supercharger to increase the engine power at altitude. However, this engine went through so many design changes that it ended up being almost identical to the later V-1710-93 which was fitted in the XP-63A . Another change was the engine bay was modified to accept
35-439: A new and thicker wing with a symmetrical airfoil ; the section chosen was NACA 0018 at the wing-root tapering to an NACA 23009 at the tip. Although the new wing has often been referred to as a laminar flow type, this was not the case. The wing span was increased to 35 ft 10 in (10.9 m) and the area to 236 ft (21.9 m ), the thicker wing allowing an increase in the fuel capacity to 150 US gallons (568 L). Design of
42-643: The United States Army Air Corps (USAAC) placed a contract with Bell allowing for the purchase of two XP-39Es ( 41-19501 and 41-19502 ) which were envisaged to be a major improvement on the P-39D series. Because of the number of changes proposed the production model was to be called the Bell P-76 . The Bell P-76 was proposed to address the poor high-altitude performance of the P-39 Airacobra by incorporating
