An auxiliary power unit (APU) includes a rotary fuel slinger, and a single~spool, two-stage turbine. The rotary fuel slinger receives a rotational drive force from the turbine, and a supply of fuel from a fuel source. The rotary fuel slinger injects the fuel into a combustor as a continuous "fuel sheet." As a result, fuel mixing and atomization inside the combustor is improved, which reduces emissions and pattern factor, which in turn increases turbine life.
La présente invention se rapporte à une unité d'alimentation auxiliaire (APU), qui comprend une bague de projection de combustible rotative, et une turbine monocorps à deux étages. La bague de projection de combustible rotative reçoit une force motrice rotationnelle de la turbine, ainsi qu'un approvisionnement en combustible d'une source de combustible. La bague de projection de combustible rotative injecte le combustible dans une chambre de combustion, sous la forme d'une <= feuille de combustible >= continue. L'invention a pour effet d'améliorer le mélange de combustible et la pulvérisation à l'intérieur de la chambre de combustion, ce qui réduit les émissions et le facteur de composition, et augmente ainsi la durée de vie de la turbine.
