The movement of aerostatic probes (balloons with equipment for transmitting scientific data on board) in the atmosphere, allows for long-term studies of Venus. The study of the atmosphere of Venus by the Vega 1.2 aerostatic probes after the balloon had ascended to an equilibrium altitude was carried out without the possibility of operating change the altitude and latitude of the drift. A number of works substantiate the methods for calculating the movement of such uncontrolled balloons during entry and during drift in the atmosphere of Venus. The use of maneuvering aerostatic probes by altitude and latitude will allow for studying Venus in a wide range of altitudes from the cloud layer to the surface at various latitudes and in various conditions. To carry out long-term controlled maneuvering of aerostatic probes, it is necessary to calculate their movement taking into account the impact of environmental conditions on them.
The movement of aerostatic probes (aerostats with equipment for transmitting scientific data on board) in the atmosphere of Venus, allows for long-term research using maneuvering in altitude and latitude. To carry out long-term controlled maneuvering of aerostatic probes, it is necessary to calculate their movement taking into account the impact of the environment on them. The report considers the methodology for determining the motion parameters (trajectory, speed, acceleration) of an aerostatic probe while controlling the mass and size parameters (volume and floating mass), as well as using the thrust of screw propellers with their energy supply from solar batteries in the atmosphere of the planet Venus. Based on modeling the influence of external operating conditions: wind speed, temperature, sunlight energy and infrared radiation depending on the altitude and position of the aerostatic probe on its parameters using mathematical modeling of motion with a number of simplifying assumptions, the considered methodology allows us to determine the parameters of its motion. Taking into account the limitations on the operability of the aerostatic probe (by temperature and pressure), its use allows us to determine the flight duration, ranges of altitudes, latitudes, and longitudes of its drift. Using the methodology, we consider the control of the aerostatic probe motion when entering into navigation and in a long drift at altitudes with favorable temperatures, as well as motion control at low altitudes in the heated layers of Venus (for a short-term descent to the surface and surfacing). Determining the parameters of the movement of an aerostatic probe in the atmosphere of Venus will make it possible to justify increasing the area and duration of research in the atmosphere of Venus with controlled maneuvering.
