Abstract:
1. A combustion apparatus for providing a controlled heat flux for testing a test specimen containing an energetic material comprising: (a) a source of air for providing a stream of air at a fixed mass flow rate; (b) an air inlet duct having said source of air positioned at one end thereof; (c) a manifold positioned at the other end of said air inlet duct, said manifold having a fuel injection system comprising a plurality of equally spaced apart fuel injectors located within said manifold which form a ring around said manifold, wherein said plurality of fuel injectors of said fuel injection system inject a liquid fuel into said stream of air forming a flammable mixture; (d) a combustion chamber having one end thereof connected to said manifold to receive said flammable mixture, said combustion chamber having an inside diameter that is larger than an inside diameter for said air inlet duct, wherein the inside diameter of said combustion chamber is eighteen inches and the inside diameter of said air inlet duct is approximately five inches; and (e) a fuel ignition device positioned in proximity to said flammable mixture, said fuel ignition device igniting said flammable mixture generating said controlled heat flux within said combustion chamber to test said test specimen which includes said energetic material.
