Scientific paper
A mathematical model of probe descent in the Jupiter atmosphere is proposed. This model is used to analyze the solution characteristics of design-ballistic, thermodynamic, and weight problems concerning the selection of the main shape parameters with allowance for the modes of probe motion; the probe is considered to have the shape of a spherically blunt cone whose mass is variable due to ablation of the heat shield. Consideration is given to the selection of the optimal cone semiangle from the condition of the deepest penetration of the probe into the atmosphere in the presence of constraints (following from the equations of weight analysis and static stability) on the maximum acceleration load and the permissible temperature.
