A propulsion system (300) for an aircraft (10) comprises a fuel reservoir (100, 800) for storing hydrogen (H2-1, H2-2) and a fuel reservoir (200) for storing hydrocarbon fuel (HC). A propulsion system may be provided with a gas turbine engine (400) comprising a fuel injection unit (500), the fuel injection unit (500) comprising: a hydrogen pilot combustion chamber (510) in fluid communication with a hydrogen fuel reservoir (100, 800) through a flow control valve (512, 542); a dual fuel main combustion chamber (520) is also provided in fluid communication with the hydrogen fuel reservoir (100, 800) through a flow control valve (522) and in fluid communication with the hydrocarbon fuel reservoir (200) through a flow control valve (532). A control system (600) is provided for controlling: a flow control valve (512, 542) controlling a flow of hydrogen from a hydrogen fuel reservoir (100, 800) to a hydrogen pilot combustion chamber (510); a flow control valve (522) controlling the flow of hydrogen from the hydrogen fuel reservoir (100, 800) to the dual fuel main combustion chamber (520); and a flow control valve (532) controlling the flow of hydrocarbon fuel (HC) from the hydrocarbon fuel reservoir (200) to the dual fuel main combustion chamber (520).

    一种用于飞机(10)的推进系统(300),包括用于存储氢(H2‑1、H2‑2)的燃料储存器(100、800)和用于存储烃燃料(HC)的燃料储存器(200)。推进系统可设置包括燃料喷射单元(500)的燃气涡轮发动机(400),燃料喷射单元(500)包括:通过流量控制阀(512、542)与氢燃料储存器(100、800)流体连通的氢引燃燃烧室(510);还设置有通过流量控制阀(522)与氢燃料储存器(100、800)流体连通的,且通过流量控制阀(532)与烃燃料储存器(200)流体连通的双燃料主燃烧室(520)。控制系统(600)被设置为用于控制:流量控制阀(512、542)控制从氢燃料储存器(100、800)流向氢引燃燃烧室(510)的氢的流量;流量控制阀(522)控制从氢燃料储存器(100、800)流向双燃料主燃烧室(520)的氢的流量;以及,流量控制阀(532)控制从烃燃料储存器(200)流向双燃料主燃烧室(520)的烃燃料(HC)的流量。
