Abstract

The invention discloses a recyclable unmanned aerial vehicle booster shell. The recyclable unmanned aerial vehicle booster shell mainly comprises a flange plate and a cylinder, a circle of groove is formed by centering the center of the upper part of a front end positioning flange plate, a groove hole in a circular truncated cone shape is formed by centering the center of the groove, the bottom end surface of the groove hole is integrally connected with the bottom end of a slope surface shell in a circular truncated cone shape in a flush mode, and the slope surface shell in a circular truncated cone shape is closely connected with the groove hole in a circular truncated cone shape; the top end of the slope surface shell in a circular truncated cone shape is integrally connected with one end of the cylinder; and a circle of step part is processed on the lower part of the front end positioning flange plate. In raw materials, a silicon nitride ceramic material is used for replacing the original high temperature-resistance metal; the silicon nitride ceramic material is prepared from components in parts by mass: 95-99 parts of silicon nitride ceramic powder, 1-2 parts of metal oxide, 5-8 parts of rare earth oxide mixtures, 0-1 part of transition metal carbide, 1 part of polyvinyl alcohol, 0-2 parts of alumina and deionized water in the amount of three times the amount of the siliconnitride powder. The recyclable unmanned aerial vehicle booster shell has the advantages of high hardness, wear resistance, high and low temperature resistance and recyclability.

Description

technical field [0001] The invention relates to the field of aviation boosters, in particular to an unmanned aerial vehicle booster casing and a manufacturing method thereof. Background technique [0002] The booster is the propulsion equipment of the vehicle, which converts the power provided by the power device on the vehicle into thrust to propel the vehicle forward. It is widely used in the fields of unmanned aerial vehicles, aerospace and aviation. It generates thrust by swirling jets. Boosters are widely used in unmanned aerial vehicles, aviation and other fields, mainly as power devices for unmanned aerial vehicles, aviation and other equipment. Under the existing technical conditions, first, the booster shells are basically high-temperature-resistant metal shells and carry fuel and oxidant, which are easily damaged by the burning fuel carried during use, so they are all disposable Use, can not be reused, needs to be improved. 2. The weight reduction and safety and...
