En. Avrorin et al., NUMERICAL-SIMULATION OF THE INTERACTION OF DUST PARTICLES OF A COMET WITH A SPACECRAFT, Combustion, explosion, and shock waves, 32(2), 1996, pp. 219-224
The paper deals with the physical and mathematical statement of proble
ms that arise in estimating the safety of the shield design of the ''V
ega'' spacecraft, which was chosen preliminarily tinder the guidance o
f R. Z. Sagdeev. Numerical results for failure of shields impacted by
particles of the dusty atmosphere of Halley's comet are presented. The
size of the failure zones in the shields are determined as a function
of the particle size and density. The probability of an impact on the
second shield of the particles penetrating the shield or resulting in
spalling of solid fragments is estimated. The momentum transmitted by
the particle flux to the solar batteries of the spacecraft is determi
ned.
