ABSTRACT:
Apparatus for ejecting and dispersing a payload of passive radiation interference material into the near vicinity of a tactical aircraft comprises a cartridge case adapted for carrying and launching at least one cylindrical payload disk, the cartridge case having a lineal length of rack teeth within its bore and the payload disk having at least a portion of its exterior circumferential extent with matching gear teeth such that upon explosively pressurizing the cartridge case the payload disk is ejected exhibiting high linear and rotational velocities. The payload disk has tapered bore wall surfaces which confine the payload material and upon being ejected the spin-stabilized payload disk disperses the payload substantially uniformly within the first few milliseconds after leaving the cartridge case.
