Abstract

A jet exhaust simulator provides a multichamber jet fuel burner in which the fuel supplies to the chambers may be remotely and independently controlled, and in which a pilot flame chamber with squib igniter provides a reliable source of combustion. Primary, secondary, and tertiary fuel nozzles are provided, with the tertiary nozzles using straight venturis to inject large fuel drops into a burning fuel/air mixture in order to produce an exhaust plume closely simulating the length and infrared light emissions characteristics of a jet aircraft engine. The exhaust simulator is particularly adapted for use in a towable aerial target for the testing of infrared seeker guided shells or missles.
