Pulse pre-detonating detonation engine capable of working stably

A detonation engine is composed of a pre-detonating combustion tube (1), spiral blades (2), a fuel air premixing chamber (3), a negative electrode supercharging base stack (10), a positive electrode rotating supercharging base stack (13), a premixing chamber internal spiral flow guide strip (14), a pre-detonating combustion tube external spiral flow guide strip (15), a high pressure ignition control ECU (19) and a detonation spray tube (22). The premixing chamber internal spiral flow guide strip (14) and the pre-detonating combustion tube external spiral flow guide strip (15) enable an explosive gas mixture to be mixed fully and form a vortex airflow, the gas mixture is ignited by a combusting airflow at a gathering position, detonation happens, and thus the situation that the explosive gas mixture detonates is ensured. The detonation engine has the advantages of being (1)capable of solving explosive initiation, control and rapid maintaining of detonation, (2) capable of achieving atomization, spraying, and mixing of liquid fuel and an oxidizing agent, and (3) capable of generating stable pushing force, and achieving high frequency operation. The detonation engine solves the main problems faced by pulse detonation engines at the same time, and has good marketing prospects.
