    • The invention relates to a method for starting a spacecraft engine combustion wherein: a propellant tank heater (25) is ignited; a first tank (23), containing the first propellant, and a second tank (24), containing a second propellant, are pressurized once the heater (25) reaches a stable state, and a first tank (13) of igniter of the first gas propellant and a second tank (14) of igniter of the second gas propellant are respectively filled, in parallel, until ignition threshold values for temperature (T13, T14) and pressure (P13, P14) are reached; and the first and second gas propellants, contained in the first (13) and second (14) igniter tanks, are injected into an igniter (12) of the engine such as to initiate combustion.
    • 本发明涉及一种用于启动航天器发动机燃烧的方法,其中:推进剂箱加热器(25)被点燃; 一旦加热器(25)达到稳定状态,包含第一推进剂的第一罐(23)和包含第二推进剂的第二罐(24)被加压,并且第一罐(13) 并行地填充气体推进剂和第二气体推进剂的点火器的第二罐(14),直到达到用于温度(T13,T14)和压力(P13,P14)的点火阈值; 并且容纳在第一(13)和第二(14)点火器罐中的第一和第二气体推进剂被喷射到发动机的点火器(12)中以便开始燃烧。
