Radioactive material with alpha particle cascade decay, propelling plant adopting same and lotus seed propeller

Abstract

The invention discloses a radioactive material with alpha particle cascade decay, a propelling plant adopting the same and a lotus seed propeller. The propelling plant generates propelling force in the mode that the adopted radioactive material radiates high-energy particles through an alpha particle cascade decay reaction. One gram of 242 Cm radioactive element with the half-life period being 163 days can provide propelling force of 3-5 muN, and One gram of 238 Pu radioactive element with the half-life period being 87 years can provide propelling force of 0.02 muN. The propelling plant which adopts the radioactive material and has a specific surface shape can provide propelling force in a specific direction which is perpendicular to the focus plane of the propelling plant. The radioactive material can provide stable propelling force for hundreds years, and is particularly suitable for micro propellers and high-power propellers.

Problems solved by technology

[0003] The current international mainstream space electric propulsion is based on technologies such as high-voltage accelerated ions based on mesh anodes, microwave cyclotron resonance accelerated ions, and Hall magnetic induction principle accelerated ions, all of which require high-voltage power supplies, magnetic fields, vacuum pumps and complex supporting devices to achieve The propulsion function is large in size and weight, and the subsystems are complex and prone to failure. It is difficult to achieve stable propulsion for hundreds of years

[0004] In order to solve the above-mentioned problems, the solutions adopted in the prior art, but these solutions themselves have the following defects: today, small satellites, micro-satellites and nano-satellites have advantages such as short development cycle, low cost, small risk, and great military application prospects. Become the development trend of contemporary satellite

High-energy ion propulsion can generate corresponding thrust, but it is not suitable for small satellites because of the need for power supply, magnetic field, and complex vacuum system
