“…The characteristics of PROTEUS machine suggests that optimizing its ability to perform site characterization through the extraction of core samples requires the adoption of the so-called wireline technology; as known in literature [9] such technique presents a number of advantages in comparison with other surface-driven rotary drilling technologies, main one being the ability to reduce tripping pipe time.…”

The PROTEUS project involves the construction of a self-propelled and floating amphibious machine for near shore geological surveys. In this context, the development of a wireline core drilling device was tackled, evolving with respect to existing models and responding to the specificities of the new application. In the preliminary phase, comparative research was carried out both through market research and through reverse engineering activities on core drill models deemed suitable for the purpose, thus identifying the functional priorities and criticalities of the existing material through the ex-post analysis of the subject elements to wear and tear. Once the requirements of the new core drilling device were formalized, the constructive layout was defined, giving priority to functions such as sample management, interlocking and rapid disengagement from the drilling actuation system. The construction details of the mechanical coupling profiles were then optimized by simulation in a multibody software environment, in order to ensure full functionality even in harsh environments, typical of the application, making an advancement with respect to the previously identified reference solutions. Finally, the executive design of the component was carried out by introducing the corrections deriving from the simulation results and considering different solutions in relation to the material adopted and its production needs through machining processes.

“…There has been some success in collecting debris-containing ice and bedrock samples with tethered systems; however, the reliability of current systems to collect bedrock is somewhat low and the risk of sticking and losing downhole equipment is increased (Bentley and others, 2007; Talalay, 2013). Further development of tethered systems could mitigate risk and increase capability but there are limitations to the adaptability of bedrock interfaces (Wang and others, 2015). After evaluation of current and readily available technology, IDP decided that a diamond-coring rig would have the highest probability of success of meeting the science requirements outlined in Table 1.…”

Adaptation of the Winkie Drill for subglacial bedrock sampling

et al. 2020

The Winkie Drill is an agile, commercially available rock coring system. The U.S. Ice Drilling Program has modified a Winkie Drill for subglacial rock and ice/rock interface coring, as well as drilling and coring access holes through ice. The original gasoline engine was replaced with an electric motor though the two-speed gear reducer and Unipress hand feed system were maintained. Using standard aluminum AW34 drill rod (for 33.5 mm diameter core), the system has a depth capability of 120 m. The drill uses forward fluid circulation in a closed loop system. The drilling fluid is Isopar K, selected for favorable properties in polar environment. When firn or snow is present at the drill site, casing with an inflatable packer can be deployed to contain the drill fluid. The Winkie Drill will operate from sea level to high altitudes and operation results in minimal environmental impact. The drill can be easily and quickly assembled and disassembled in the field by two people. All components can be transported by Twin Otter or helicopter to the field site.

“…The traditional rotary drilling technology is difficult to operate in a weak gravitational environment and hard rock formations due to problems such as high-required axial force, continuous holding torque, high power consumption, large mass, inability to circulate effectively, and severe wear of the drill bit [5][6][7] . In order to better realize the efficient sampling of hard objects of extraterrestrial celestial rocks, domestic and foreign scholars and institutions have carried out a lot of research on extraterrestrial rock sampling technology, including projectile sputtering sampling technology [8][9][10] , cutting sampling technology 11 , impact and coring sampling technology [12][13], pneumatic sampling technology 14 , impact and ultrasonic vibration drilling sampling technology [15][16][17][18][19][20][21][22][23][24][25][26][27][28] , etc.…”

The traditional rotary drilling technology has the problems of high-required axial force, high power consumption, large mass and serious wear of the drill bit. It is difficult to be better applied in the detection of extraterrestrial celestial bodies with weak gravitational environment and hard rock layers. The high-frequency micro-amplitude impactor can greatly reduce the drilling pressure and power consumption by using high-frequency impact to drill objects with high hardness such as rocks. Therefore, based on the piezoelectric transducer, a high-frequency micro-amplitude impactor is designed by analyzing the configuration of the horn and the collision system of the spring-mass system. It is verified that the no-load frequency of the impactor is above 1000Hz, and that the amplitude is about 0.2mm. Finally, the validity of the design of the high-frequency and micro-amplitude impactor is verified by the sandstone-drilling experiment.
