BELL MODEL 48 ( XH-12 )


Title: Bell Model 48 (XH-12)

The Bell Model 48 was Bell’s first attempt at a larger utility helicopter and used what was effectively a scaled up version of the Bell 47’s two-blade rotor system. A single XH-12 and 10 YH-12 examples were built, but there were problems with the performance of the main rotor and further development was discontinued.
