Bell P-39D Airacobra for X-Plane 11
The Bell P-39 Airacobra was one of the principal American fighter aircraft in service when the United States entered World War II. The P-39 was used by the Soviet Air Force, and scored the highest number of individual kills attributed to any U.S. fighter type in the Eastern European theatre. Other major users of the type included the Free French, the Royal Air Force, the Royal Australian Air Force, the United States Army Air Forces, and the Italian Co-Belligerent Air Force.
Designed by Bell Aircraft, it had an innovative layout, with the engine installed in the center fuselage, behind the pilot, and driving a tractor propeller via a long shaft. It was also the first fighter fitted with a tricycle undercarriage. Although its mid-engine placement was innovative, the P-39 design was handicapped by the absence of an efficient turbo-supercharger, preventing it from performing high-altitude work. As such it was rejected by the RAF for use over western Europe but adopted by the USSR where most air combat took place at medium and lower altitudes.
Together with the derivative P-63 Kingcobra, the P-39 was one of the most successful fixed-wing aircraft manufactured by Bell.
