Coaxial machine-gun/main-tank-gun weapons effects simulator

Abstract

The invention comprises a combined machine gun and large bore cannon weapons effects signature simulator having a rapid fire small bore methane and oxygen fired combustion chamber disposed within the combustion chamber of a large bore main tank gun weapons effects signature simulator and supplied from a common source of pressurized methane and oxygen. One embodiment includes the injection of ambient temperature oil into the large bore chamber prior to firing the combustible mixture to augment the flame content of the weapon signature. Another embodiment provides for the emission of hot oil vapor to augment the smoke content of the weapon signature. Yet another embodiment provides the machine gun simulator combustion chamber integral with and in intimate thermal contact with the wall of the large bore combustion chamber, whereby the machine gun combustion chamber utilizes the large bore combustion chamber wall to dissipate heat. Still another embodiment provides a large bore combustion chamber coaxially and distally extending from the distal end of the small bore combustion chamber, whereby the large bore combustion chamber may be filled through the small bore combustion chamber with methane and oxygen, and ignition of all of the combustible mixture is initiated in the small bore combustion chamber.
