Abstract

1421399 Burners SOC NATIONALE D’- ETUDE ET DE CONSTRUCTION DE MOTEURS D’AVIATION 7 Nov 1973 [13 Nov 1972 26 Oct 1973] 51579/73 Heading F4T A fuel injector, e.g. for a jet propulsion engine, comprises a tubular duct 103 closed at its upstream end by a plate 105, and an annular passage 104 directing a swirling annular stream of fuel 125 into duct 103 such that the fuel stream is sandwiched between inner and outer airstreams 124, 115 directed through centripetal and further swirl blades 107, 32 respectively. The latter blades 32 may be centripetal, as shown, or axial. An additional annular stream of fuel 45 may be supplied through passage 38 as well as a third air stream 44 from swirlers 106. The fuel is supplied to the injector via a fitting 43 having a first duct 121 leading to the interior 120 of plate 105 which connects with annular chamber 116 via ducts 122 passing through swirler 107. The fuel cools plate 105. A second duct 42 in fitting 43 supplies fuel to annular chambers 40 via ducts 41. The flows through ducts 42, 121 can be independently controlled, duct 42 being closed at low speed engine operation. The airstreams may be arranged to swirl in the same or opposite directions. In modifications (Figs. 2, 4, not shown) the additional fuel stream and the third airstream are not provided. The constructions reduce coking of end plate 105 and formation of nitrogen oxides whilst improving atomization and combustion of the fuel.
