Development of an Engine-Powered Liquid Dispersal System for Agricultural Aircraft

摘要

The report presents the results of efforts to design, a liquid dispersal system for agricultural aircraft which would have low power requirements as compared to standard windmill powered pump systems. The resulting system consisted of a standard spray pump powered from the aircraft engine accessory pad and a spray boom mounted in the wing wake. The maximum power requirement of the final configuration was 12.5 brake horsepower at 100 miles per hour as compared to 52 brake horsepower for the standard system. Significant increases in climb performance and reduction of level flight power requirements were measured. No adverse effects on stall characteristics and control feedback were noted. (Author)
