Determining the geotechnical properties of planetary regolith using Low Velocity Penetrometers

摘要: Abstract Measurements of mechanical and thermophysical properties planetary surface allow determining many important parameters useful for planetologists. For example, effective heat conductivity or thermal inertia the regolith can help to better understand processes occurring in bodies interior. Chemical mineralogical composition gives us a chance determine origin evolution moons satellites. Mechanical are one key factors needed by civil engineers developing future bases on space bodies. Space missions highly restrict payload concerning its mass power consumption. Therefore, it is quite impossible use standard terrestrial technique like Load Plate Test Direct Shear Tests geotechnical regolith. Even Dynamic Cone Penetration (DCP) method, which frequently used field testing, does not fit well with constraints imposed mission. Nevertheless, operation principle very similar that at Low Velocity Penetrators (LVP), several them being currently their way (e.g. MUPUS instrument) were developed last couple years CHOMIK instrument KRET device). In this paper we present comparison between DCP method LVP was observed during tests campaigns mole development. The performed different analogues: JSC-1A, Chenobi AGK-2010, Phobos analogue, cometary analogues F1, F2 F3 (SRC) dry quartz sand. part concept results׳ interpretation presented.
