Bell Tiltrotor Aircraft
Bell Helicopter Textron
Bell D-326 Clipper
Project in 1966, Bell continued to ponder about developing a tilting proprotor aircraft. Extensive research on the XV-3's problems, such as the proprotor stability problem, continued. Eventually many of the XV-3's problems were solved, and thus Bell was poised to tackle another tilt rotor project. The following tiltrotors display the concept-development of what would ultimately become the Bell XV-15.

The following aircraft show the progression of designs that led to the XV-3.
