Improving inertial separating penetrators considering the features of their impact penetration into the studied celestial bodies

Abstract

The article considers factors that can negatively affect the creation of reliable radio communication between an inertial separating penetrator after its impact penetration into the soil of the studied celestial body and an orbital vehicle. The authors conduct the calculation and analysis of overloads acting to the forward head and antenna parts. Moreover, the research demonstrates that the overload on the antenna part can be dozens of times greater than on the forward head. The authors also present the calculation and analysis of the input diameters of the funnels formed from the impact penetration of the penetrator into different soils of the studied celestial body. The research considers possibilities of improving penetrators by using segmented, telescopic and hybrid tips, as well as reverse shooting of the antenna, which allow reducing the impact speed and overloads during impact penetration of the penetrator into the soil of the studied celestial body.
