Embodiment Construction
[0008] The present invention will be further described below in conjunction with accompanying drawing
[0009] Small thrust engine heads such as figure 1 shown. The small-thrust engine head consists of point oxygen nozzle (1), hydrogen welding nozzle (2), hydrogen nozzle (3), niobium sheet (4), resonant cavity (5), resonant tube (6), resonant head (7) , thermal insulation cover (8), overcoat (9), main oxygen welding nozzle (10), main oxygen nozzle (11), sealing head (12).
[0010] The oxygen point nozzle (1) is installed in the hydrogen nozzle (2), and the oxygen point nozzle (1) is located at the center, the two are coaxial and connected by welding. The side of the hydrogen nozzle (3) has holes and is connected with the hydrogen welding nozzle (2) by welding. The oxygen point nozzle (1), the hydrogen nozzle (2) and the hydrogen welding nozzle (3) together constitute the igniter nozzle structure.
[0011] The niobium sheet (4), the resonant cavity (5), the resonant tube (6...
