The invention belongs to the technical field of blasting, and particularly relates to a blasting oxygenation device and method adaptive to a plateau low-oxygen environment, the device aims at solving the problem that explosive blasting reaction is incomplete in the plateau hypoxia environment, the device comprises a charging bag placed in a blasting hole, an oxygenation device, a partition device and a sealing plug, the oxygenation device is provided with a shell and a liner bag, and the liner bag is provided with an opening. The inner container bag stores oxygen, the partition device is composed of an upper cover plate and an annular air bag, the oxygen increasing device and the partition device are arranged between every two vertically adjacent charging bags, the sealing plug is located at the top of the blast hole, and when the charging bags are detonated, generated shock waves can enable the inner container bag of the oxygen increasing device to be broken to release oxygen, and meanwhile the annular air bag of the partition device is pushed to expand to seal the hole wall. According to the device, oxygen release and sealing are triggered by means of explosion energy, oxygen is supplemented for a reaction area at the moment of explosion, oxygen is prevented from overflowing, and the plateau explosion effect can be improved.

To address the limitations of existing pulse detonation combustors using detonation jet ignition, which require long jet tubes and thus restrict the increase of their operating frequency, and the dependence of stable operation of pulse detonation turbine engines on the performance and reliability of the igniter, this invention proposes a pulse detonation combustor based on rotating detonation wave ignition. This invention utilizes the relatively high frequency of rotating detonation combustion and the requirement for only a single ignition. The rotating detonation wave generated by the rotating detonation chamber serves as a continuous high-energy ignition source, igniting the explosive mixture within the detonation jet channel. This creates a high-energy detonation jet at the channel's exit, which then flows into the pulse detonation tube and ignites the explosive mixture within. This invention, while maintaining the excellent initiation performance of the detonation jet ignition method, overcomes the adverse effects of long jet tubes and high-frequency ignition on the efficient and stable operation of pulse detonation turbine engines.

The invention relates to the field of energetic materials, in particular to an implementation method of a high-burning-rate compound. The molecular formula of the high-burning-rate compound is C6H16N2 (NH4) (ClO4) 3, compared with DAP-4, the distance between C-O and N-O of the high-burning-rate compound is shorter, and the reduction of the spacing between atoms can aggravate the redox reaction between HDX-1 atoms, so that the burning reaction process is more violent, and the burning rate of the molecular perovskite energetic material is improved. The preparation process is mild in condition, safe, environmentally friendly and easy to amplify, and has a good application prospect in the field of high-burning-rate propellants.
