<p>The invention relates to a jet engine having a spiral-shaped conical burner and using in its construction the oxygen in the air. According to the invention, the engine comprises a spiral-shaped conical burner (1), a secondary burner (2), an injection nozzle (3), an air limiting filter (4), an intake chamber (5) and an exhaust chamber (6), the spiral-shaped conical burner (1) consisting of a metal or non-metal strip (9) spirally-wound as a cone, between the successive turns of the strip (9) there being created a narrow space (8) having the same size for each turn wound about an axis X and at a cyclic distance (11) on another axis, Y, in the cone apex there being placed a maintaining burner (2) intended to maintain the ignition and an injection nozzle (3) placed around the flame produced by the maintaining burner (2), the fuel jet flow rate having a caloric value which is sufficient for the flame to adhere to the internal surface of the spiral cone due to the Coanda effect, so that a successive air absorption is produced through the narrow spaces (8), from the exterior of the cone inwards, to achieve a successive mixture.</p> |
