Aerial Distributors Aerial Distributors was a US aircraft manufacturer established in Wichita, Kansas in 1967. It set up to develop the Distributor Wing DWA-1, an unorthodox agricultural aircraft. Aerial Distributors Distributor Wing DW-1 Role - Agricultural aircraft Manufacturer - Aerial Distributors Designer - Ken Razak First flight - 30 January 1965 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 Developed with assistance from NASA, the University of Wichita and the University of Robbins, California, 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. Development was terminated by economic conditions in the fertilizer market.
