From Wikipedia, the free encyclopedia

The Aerial Distributors Distributor Wing was a prototype agricultural aircraft of unorthodox design designed by Ken Razak and built in the United States in 1965. 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.

Development was terminated by economic conditions in the fertilizer market.
