Design Blueprint: A Rotary-Percussive Drill for Three-Metre Lunar Regolith Cores Sized from Shear and Cutting-Energy Bounds

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24151886): This paper presents the sizing of a surface system for the Moon, designed around a single operating principle and computed from published material properties of its working environment. The headline results are: target depth of 3 m; total cutting energy of 0.068 MJ; rate of penetration of 0.6 m/h. The total mass is 49.8 kg including a twenty percent margin over the component subtotal. Every figure was produced by the accompanying computation script from stated assumptions about density, strength, thermal properties and composition; no figure is asserted without its derivation. Weak points of t Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
