Vanguard Model 2D Omniplane
Modifications to the Omniplane 2C in 1961, including an improved control system, upgrading to a 860 hp Lycoming YT53-L-1 turboshaft engine, and 5 ft nose extension to house a third lifting propeller, led to the redesignation 2D. The nose propeller improved control in pitch as well as in yaw, through the use of movable exit vanes.
The 2D completed tethered hover tests, but was damaged by a mechanical failure and discontinued in early 1962.
