Abstract: PROBLEM TO BE SOLVED: To optimize mixing characteristic of two fluids crossing in a jet engine part orthogonally. SOLUTION: In an air mixing device for mixing primary fluid with secondary fluid introduced through an opening part of a wall and flowing on a wall face, the opening part has an airfoil shape provided with a leading edge oriented at a certain angle of attack with respect to secondary fluid flow to promote penetration and dispersion of the primary fluid stream into the secondary fluid stream. The airfoil shaped opening part is selectively positioned to give desired lift for optimizing mixing of two streams by the angle of attack in accordance with the particular application. In one embodiment, a collar is provided around the opening part to prevent secondary fluid from coming into contact with the wall face during certain operation condition. A plurality of opening parts may be used by combination of a large size airfoil-shaped opening part and a small size airfoil-shaped opening part arranged on the downstream side more than it and combination of the airfoil-shaped opening part and a round-shaped opening part arranged on the upstream side more than it. A pair of opening parts and associated collars may be symmetrically arranged to promote mixture in specific application, and a nozzle may be arranged on an inner side of a wall to improve stream characteristic of primary fluid.

Abstract: A fuel system for a gas turbine engine comprises an injector disposed to inject fuel and air into a combustor of the gas turbine engine. In a first embodiment, the fuel system further comprises an air separation module configured to supply oxygen-enriched air into the combustor via the injector for combustion. In a second embodiment, the fuel system further comprises a barbotage system and a heating element. The barbotage system is configured to feed hydrogen to the injector, and the heating element is configured to pre-heat the fuel.
