A publicity photo of the BAT (Bell Advanced Tiltrotor), a circa 1984 concept for a one-man attack tiltrotor to complete in the Army scout helicopter program (LHX – Light Helicopter Experimental) that led to the abortive RAH-66 Comanche. Shown here is a full-scale mockup; the prop-rotors as shown are substantially chopped down from the length they’d be on the actual aircraft. The BAT would have outperformed all other competitors except for hover performance; but the Army did not want a fixed-wing vehicle, so the BAT did not progress very far in the competition.
