ABSTRACT:
A nozzle assembly for a rocket type decoy used to protect aircraft from missile attack. The nozzle assembly includes an annular chamber and a mixing chamber which is spaced radially inward from the annular chamber. The chambers are separated by a wall and interconnected by multiple jet ports formed in the wall. The nozzle assembly is positioned adjacent to a conventional rocket combustion chamber such that when energetic compositions are reacted in the chamber, the combustion products flow into the annular chamber, radially inward through the multiple jet ports, and into the mixing chamber. Chaotic mixing of the combustion products occurs in the mixing chamber to improve combustion efficiency and reduce combustion products pass from the mixing chamber through the nozzle exit plane thus producing reduced thrust with enhanced radiation intensity.
