ABSTRACT:
Payload delivery of a payload compartment containing a delivery device is initiated by a suitable fusing device which ejects the delivery device from a payload section by firing a gas generator in the section base to propel the delivery device forwardly, thereby shearing retaining pins and ejecting the delivery device from the payload section. The fusing device concurrently fires a time-delayed mechanism leading to a second gas generator in the center of the delivery device. The gas generator ignites after the chaff dispenser is clear of the payload section. The ignition reaction pneumatically blows chaff (e.g. metallized dipoles) out of wrapped bundles, leaving the wrapper bonded to the delivery device and disseminating the chaff in a cloud of hot gas and air turbulently mixed in the wind shear occurring in the wake of the delivery device. The delivery device survives the dispensing and dissemination processes without losing structural integrity. Thus, no harmful debris is ejected into the chaff cloud. The generated gases disseminate the chaff and contain no component (e.g. carbon monoxide or hydrogen) combustible in air thereby precluding ignition of the metallized coating of the chaff. This maintains the chaff as electrical dipoles. The gas temperature is controlled by endothermic decomposition of companion salts in the center of the device to avoid chaff oxidation as the chaff is mixed with air during such dissemination. Chemicals mixed with the chaff react at an elevated temperature below the chaff oxidizing temperature to provide a distinctive color to the chaff without chaff oxidation.
