Нелинейная радиофизика межзвездных перелетов: разгон макрообъектов с помощью электромагнитного излучения

Abstract

We discusses one of the implementations of acceleration, based on powerful artificial radiation, of spacecraft capable of reaching the nearest stars in the constellation Alpha Centauri in twenty to thirty years (i.e., during the active life of one generation of people). The Breakthrough Starshot project (BS, Breakthrough: Starshot) was proposed in 2016. The key new aspects of the project are: 1) the idea of interstellar vehicles of ultra-small dimension, which makes the physical parameters of the project potentially achievable in the foreseeable future; 2) modular construction of the launch system and 3) extension of Moore's law to the development of space technology. As an alternative to the linear “BS” type scheme, a closed ring scheme for laser acceleration of macro-objects is considered below. It is shown to be promising for dramatically reducing the peak requirements for a linear-type micro spacecraft launch.
