Abstract As a useful equipment for ice sheet exploration, many Philberth thermal probe designs have been proposed for use on Earth or extraterrestrial planets. The classic method for calculating the power consumption of a Philberth thermal probe can be modified by assuming a reasonable thermal head efficiency. The influence of various parameters on the critical refreezing length and the power consumption of the thermal head and lateral heater are evaluated using the improved method. The power co...

Abstract Borehole closure owing to the refreezing of meltwater poses a serious limitation in ice thermal drilling, and estimates of the refreezing rate are essential for determining safe drilling rates. In this paper, we describe the results of water cooling and freezing experiments in cylindrical ice holes with a diameter of 200 mm at a setup temperature within the range of −20 to −50 °C. These experiments represent a new means of estimating cooling/refreezing rates using two mutually perpendic...

As a result of the severe natural environment with oxygen deficit in the Antarctic, using conventional manual work to screw and unscrew the drill pipe increases the labor intensity tremendously and causes an efficiency reduction. Therefore, it would be useful to design a clamper inside the drilling shelter, which could help to assemble and disassemble the ice core barrel with screw connection. This paper describes the design of and experiments with the clamper inside the movable drilling shelter...

Abstract Electrically heated hot points are widely used for drilling in glaciers and ice sheets. To study the effect of input power, axial load, ice temperature, shape, and material of the thermal tip on the hot-point rate of penetration (ROP), a 0.8-m-long drill with 18 changeable thermal tips was designed. The ROP increased with input power for all the thermal tips. Seven tip shapes (cylinder, cosine, ogive, sphere, catenary, parabola, and cone) were tested at the same power level, axial load,...
