Theory and Engineering Design of Continuous Harmonic SGDM Graviton Propulsion Drive: 4-Phase Modulation and 5-Motor Power Assembly Author: Yuri A. Chesnokov (President of NAP Russia, Physics & Tech. Dept. DSU 1984) Core Concept Publication of the SGDM Series: DOI: 10.5281/zenodo.23191063 Official Research Portal: multiverse.asistent-aiart.ru/en/ Abstract: Development of predictive harmonic phase modulation for the SGDM graviton drive: converting precession braking into a second forward thrust stroke (-ω_x × -Ω_p > 0). Demonstrates continuous sine-squared thrust (F ~ sin²ωt ≥ 0), strictly zero dynamic jerk (Jerk ≡ 0), direct torque transfer via pivot gear hubs (R_gear = L), and 100% mechanical/electrical energy balance convergence for a 5-motor assembly (58 kW mean / 116 kW peak) piloting a 1.0-ton vessel to Mars in 90 days.
