Abstract
Abstract An antipollution jet engine in which air is fed through the chamber walls of the combustion chamber downstream of the fuel oil nozzle. The air is caused to have a tangential swirling motion to assist in obtaining a complete burning mixture so as to burn all combustible material in the fuel to eliminate pollution. Additional fuel is supplied to a downstream burner similarly provided with downstream air admission ports to create a circular tangential turbulence for a complete mixing and complete burning of the combustible materials. The function of the downstream burner is to assist in completely burning all of the combustible materials resulting from the first burners. The fuel for the first burners and the downstream burner is preheated to improve ignition and burning.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
291 words
An antipollution jet engine including a plurality of main burners each of said main burners including a combustion chamber, a fuel nozzle secured in one end of said combustion chamber, a supply of primary air connected to said one end of said combustion chamber, a supply of additional air passing through a plurality of bores in said combustion chamber sloped to direct the additional air tangentially and downstream to create a swirling action therein, said combustion chamber having a reduced diameter extension on the end thereof opposite said one end, said extension providing a downstream final burner and cooling section of said main burner and having a plurality of air directing bores to direct additional air tangentially and downstream, means detachably mounting said main burners in said jet engine, a downstream combustion chamber in said jet engine to receive the collective products of combustion of said main burners, a reduced diameter extension on said downstream combustion chamber, means for providing fuel to said downstream combustion chamber, means for supplying air to said downstream combustion chamber, a plurality of auxiliary jet engines mounted on said jet engine with the axes thereof parallel to the axis of said jet engine, means on said jet engine cooperating with means on said auxiliary jet engines for reversing the direction of said auxiliary jet engines for braking action, means for supplying fuel to said auxiliary jet engines, means for supplying air to said auxiliary jet engines from the additional air supply of said jet engine, means cooperating with said reversing means for interrupting the flow of fuel and air to said auxiliary jet engine during the reversing thereof, and selectively actuatable means for controlling the air supply to said main bUrners and the additional air supply.
