Embodiment Construction
[0023] The present invention is a liquid rocket engine thrust chamber with variable working conditions, such as figure 1 and 2 As shown, it includes: the head body 2, which is a rotary shell structure, the cross section of the rotary shell is circular, and an annular cavity is formed in the shell; the center of the head body 2 is used for axially setting the igniter; the circle An igniter mounting seat 11 is installed in the center of the ring, and the igniter mounting seat 11 is a support. Two groups of gas-liquid outlet holes are opened at the bottom of the rotary housing, and each group is two. The rotary housing includes: a conical housing, with a through hole axially opened at the central axis, and annular cavities with different diameters are formed in the housing; a cylindrical housing, integrally connected with the lower end of the conical housing, and a A through hole is opened in the axial direction, and an annular cavity is formed in the casing. The lower end of ...
