A Rotary Mechanical Ice Drill for Europa: Cutting Power, Torque and Penetration-Rate Budget

This paper presents a complete sizing study of the system in its title, built from named physical relations applied to a stated set of environmental inputs, with all results labelled SIMULATED, NOT MEASURED. The drill is a civilian science system intended to open an instrumented access hole into Europa's ice shell and to lower oceanographic sensors through it; it performs no function beyond peaceful subsurface exploration. Headline computed outcomes are cutting power of 236 watts, chip lift power at full depth of 285 watts and drilling duration of 222.2 days. Because every figure traces to the deposited script, a reader who disputes an input can re-run the whole argument with a different one and see exactly which conclusions move.
