Spray Tank Unit, Aircraft, PAU-8/A.
Abstract
A modular spray system for anticrop chemicals was designed, developed, fabricated and tested. The system is capable of external carriage on high and low performance aircraft in four possible configurations using either one, two, three, or four modules. Each of the 50-gallon modules is completely interchangeable and can spray at rates from 15 to 150 gallons per minute. The modules use a compressed-air/gas reservoir to pressurize the agent reservoir and force the agent out the nozzle. Support equipment, designed and delivered with the dispenser, included the loading and handling adapter kit for the MJ-1 and MHU-83E bomb lift trucks, the checkout unit, and the anticontamination kit for use with the F-4 aircraft. Nozzle tests were conducted from aircraft at 198 to 504 knots. Droplet sizes of 105 to 555 micron mmd were obtained with the single module configuration at air speeds of 214 to 354 knots. Full scale flow model tests of the agent tank lead to the development of a module which expels 99 percent of the agent from the module at a flow rate of 150 gallons per minute. Scale wind tunnel and jettison flight tests were conducted to support the design of a stable two-module configuration. (Author)
