[0002] The pulse detonation engine uses pulsed detonation waves to generate thrust. It has the advantages of high thermal cycle efficiency, low fuel consumption rate, high thrust-to-weight ratio and large unit volume. The pulse detonation engine (PDE) is a type of detonation engine. Its working principle is to use a mixture of fuel and oxidizer to complete combustion in a very short time, release huge energy and form a detonation wave. This detonation wave is generated periodically, driving the piston or turbine of the engine to work, thereby generating thrust. Compared with traditional engines, the structure of the pulse detonation engine is simpler and does not require large turbines, compressors and other components, reducing the overall weight and structural complexity of the engine. Since the fuel and oxidizer mixture completes combustion in a very short time during the detonation process, releasing huge energy, the pulse detonation engine has a large thrust. The controllability of the detonation phenomenon gives the pulse detonation engine a significant advantage in response speed.

[0007] Further preferably, the ignition charge is ignited through a semiconductor bridge, and the semiconductor bridge is electrically connected to two electrodes, and the two electrodes are respectively a positive electrode and a negative electrode.
[0008] Further preferably, the ignition charge is used to ignite the secondary explosive and provide a force to the mass block after combustion.
[0009] A method for using a pulse push device comprises the following steps: S1: When in use, first energize the electrode so that the semiconductor bridge ignites the ignition charge; S2: Then the ignition charge ignites the high explosive, and the high explosive deflagration produces an impact force on the mass block, while the mass block provides reverse thrust due to its own mass inertia; S3: The required thrust and less explosive amount are obtained by adjusting the mass weight and the amount of explosive to optimize the volume of the device.
[0010] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, a semiconductor bridge is used for ignition. Compared with a traditional spark plug for ignition, the semiconductor bridge has a very high ignition energy and can quickly ignite and detonate explosives for driving.
[0011] In the present invention, the form of explosive-driven mass block is adopted, which has a faster response speed than the conventional gas jet pulse engine and can be applied to high-speed scenarios. At the same time, the energy of the explosion of the explosive is converted into the kinetic energy of the mass block. Compared with the direct ejection of combustion or explosion products, it can more effectively utilize energy and transmit thrust. At the same time, by adjusting the mass block and the amount of explosive, a better thrust than the gas jet pulse engine can be obtained under the same volume specifications, which is beneficial to optimizing the volume of the device.
