Description

Technical Field

[0001] The invention belongs to the field of artificial rainfall enhancement and hail prevention rockets, and in particular relates to a segmented self-destruction rainfall enhancement and hail prevention rocket. Background Art

[0002] my country is a country with severe water shortage and frequent meteorological disasters. Artificial weather modification is one of the important means of disaster prevention and mitigation in meteorological science and technology. Rain-making and hail-prevention rockets have many advantages, such as large catalyst carrying capacity, high nucleation rate, high launch altitude, and easy operation. Therefore, they have been rapidly promoted and applied throughout the country.

[0003] However, the current rain-increasing and hail-preventing rockets still have the following shortcomings in structural design:

[0004] 1) The BL series rockets are typical representatives of traditional explosive self-destruction rain-enhancing and hail-prevention rockets. The BL series rockets have three self-destruction bodies concentrated in the middle section of the rocket body as a safe landing device. When the self-destruction device is working, the three self-destruction bodies move to the head, middle and tail of the rocket body respectively under the action of gunpowder gas, and then the pyrotechnics in the three self-destruction bodies explode simultaneously. Due to the reliability of the ignition mechanism and the residual powder in the solid propellant combustion, the three self-destruction bodies often hardly move or are hindered during the movement and cannot move to the predetermined position, resulting in the head and tail of the rocket body cannot be blown up and fall as large pieces of debris, causing damage to personnel, buildings, farmland, livestock, etc.

[0005] 2) Traditional explosive self-destructive rain-increasing and hail-prevention rockets use pyrotechnic delay tubes as delay devices. During the rocket launch phase, all pyrotechnic delay tubes are ignited simultaneously, and different lengths of delay charges burn for different times to control the catalyst spreading and self-destruction time. The delay charge is affected by the production of raw materials, processing technology, assembly process, etc., so the delay time deviation is large and the operation is unreliable.
