The Distributor Wing DW-1 was a prototype agricultural aircraft of unorthodox design, designed by Ken Razak in the United States and marketed by Aerial Distributors in the 1960s.
Design[edit]
Developed with assistance 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[edit]
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.
