| 摘要 |
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. |
