Design

Developed with assistiance from NASA, the University of Wichita and the University of Robbins, California,[1] the aircraft was unusual in that it had a second engine mounted directly below its main powerplant, using this second motor to power a distribution system that used compressed air to carry dry chemicals from a hopper and blow them out of the trailing edges of its wings, over the flaps. Varying the power of this blower engine also provided lift control.

Flight testing and cancellation

First flown on January 30, 1965, the DW-1 was flight tested over several years, with the cowling being revised during testing.[1] Development was terminated by economic conditions in the fertilizer market.
