Abstract

The article is devoted to the analysis of issues related to the descent and landing of the Venusian vehicle on the surface of Venus using a rotary system operating in autorotation mode. In conditions of extreme atmospheric parameters of Venus, such as high temperature, density and pressure, as well as strong gusts of crosswind, traditional braking methods using an aerodynamic shield and a parachute are not effective enough. The rotary system using autorotation offers an energy-efficient, reusable and precise solution for controlled descent and landing on the surface of Venus. During the study, two main landing schemes were developed and analyzed: landing and autorotation after separation from the lander, as well as flight along a given trajectory followed by landing in autorotation mode. These methods ensure a safe and accurate landing, reduce risks and significantly increase the scientific value of the mission. Potential problems related to the design of the Venusian vehicle with a rotary system were identified, and a detailed matrix of problems was developed that will allow the most effective use of the results of the research and apply them to the elaboration and optimization of future missions.
