Embodiment Construction
[0017] Such as figure 1 and figure 2 As shown, the three-power combination engine in which the super-combustion and sub-combustion combustion chambers coexist includes a three-dimensional internal rotation inlet 1, a turbine channel 2, a ram rocket combination channel 3 and a tail nozzle 4. When the flight Mach number is 0-2, the turbine engine 8 is ignited and working. At this time, the splitter plate 5 in the three-dimensional inner contraction inlet 1 is at the top, that is, the state ①, and the splitter plate 6 in the tail nozzle 4 is in the middle, that is, the state ① , so that the airflow can flow through both the turbine channel 2 and the ram rocket channel 3 . However, the ram rocket channel 3 is not ignited and is in a state of leakage; when the flight Mach number is 2 to 3, the rocket engine 14 and the sub-combustion combustion chamber 9 are ignited to work, and the splitter plate 5 located in the air inlet 1 rotates downward at this time, In state ②, the diverte...
