“…The stator consists of a casing, a coil, and a magnetic washer. When the penetrator penetrates, the coil is energized to generate a magnetic field, the stator is acted on by the ampere force, and the mover interacts with the stator in the opposite direction of the force, thereby driving the penetrator to penetrate downward (Feng et al, 2017).…”

A planetary penetrator is a kind of machine that can use its special structure to independently penetrate an exoplanet and sample it for storage. It is a hot research topic in the world and has important development potential in the field of deep space exploration. Based on the analysis of relevant literature, this paper classifies and compares various representative planetary penetrator projectiles around the current research status. The development progress and key technologies of the planetary penetrator are analyzed, the current technical challenges are summarized, and the development trend of the planetary penetrator has prospected. The planetary probe has a broad application prospect, and its development will provide technical support for humans to establish extraterrestrial habitat, and play an important role in the field of deep space exploration. Currently, planetary penetrator research is still in its infancy, and the field is full of possibilities that need to be explored and improved.

Impact-type penetrators are devices that apply the impact generated by their internal components to penetrate the soil. The penetration effect of the impact-type penetrators is affected by the physical parameters (e.g., mass and stiffness) of their internal constituent elements. Therefore, optimal parameters must be obtained by using a dynamic impact penetrator model to maximize the dive distance of each impact. However, the dynamic impact penetrator models are nonlinear and difficult to describe. Thus, in this paper, this work proposes a segmentation method for modeling the penetrator motion to establish an accurate dynamic model that can be divided into four states. Buffer spring pre-compression, which is introduced as a new influencing parameter to improve the performance of the penetrator, and the genetic algorithm is used for the optimization in accordance with the characteristics of the required optimization parameter set. Parameter stability is then analyzed by considering the actual project application. Then, the control variable method is employed to explore the influence of changing the obtained parameters on the penetration effect. Finally, a processing prototype designed on the basis of the acquired parameters is used for the experimental verification. This work addresses the complexity of the dynamics model of penetration and the difficulty encountered in determining the parameter values.
