Abstract
Droplet-laser interaction is a process being encountered in many Space applications: igniting fuel-oxidant mixtures in engines of different types, removing small debris fragments from low Earth orbits, etc. The present paper describes the results of ground-based research of the process of droplet breakup under the effect of a laser pulse. The laser pulse effect is simulated as momentum applied to the boundary having Gaussian distribution both in space and time. The results of simulations testify that fragmentation of a droplet begins first in the rarefaction wave following the converging compression wave caused by the pulse. The second stage of fragmentation begins on compression wave coming to the opposite border of the droplet and reflecting from the free surface of the droplet in the form of a strong rarefaction wave.
期刊介绍：
Acta Astronautica is sponsored by the International Academy of Astronautics. Content is based on original contributions in all fields of basic, engineering, life and social space sciences and of space technology related to:
The peaceful scientific exploration of space,
Its exploitation for human welfare and progress,
Conception, design, development and operation of space-borne and Earth-based systems,
In addition to regular issues, the journal publishes selected proceedings of the annual International Astronautical Congress (IAC), transactions of the IAA and special issues on topics of current interest, such as microgravity, space station technology, geostationary orbits, and space economics. Other subject areas include satellite technology, space transportation and communications, space energy, power and propulsion, astrodynamics, extraterrestrial intelligence and Earth observations.
