Thrust chamber device and method for operating thrust chamber device

The invention relates to an improved method for operating a thrust chamber device and to a thrust chamber device, comprising a thrust chamber having a thrust space having three adjacent sections. Thethrust space is delimited in all three sections by an outer nozzle wall having an outer thrust space surface. The outer thrust space surface tapers in the first and second section, has a narrowest point at the interface between the second and third section, and widens away in the third section. The first section is also delimited by a tapering inner nozzle wall having an inner thrust space surface. An annular combustion chamber is formed between the inner thrust space surface and the outer thrust space surface. The thrust chamber device also comprises a plurality of first propellant inlets fora first propellant component and a plurality of second propellant inlets for a second propellant component, wherein the outer nozzle wall comprises at least some of the plurality of first propellantinlets. 本发明涉及一种推力室装置，包括具有推力
