A rotary-sonic drilling system was designed, built, and tested at Earth and Martian atmospheric pressures and the performance was compared against that of rotary and rotary-percussive drills. The sonic drilling technique uses vibrations to create resonance in the drill string to improve drilling performance and assist with cuttings removal. Tests were performed using a full-faced drill bit to a depth of 1 meter. Data from these tests demonstrated improved drilling performance of rotary-sonic over rotary drilling. However, for these set of tests, the rotary-percussive drill out performed the rotary-sonic drilling technique. Future testing should be done to evaluate and compare the sonic drilling method to other methods for capturing cores and for reaching depths in the 10 meter range.
