<b>A Theoretical Asymmetric Inertial Propulsion System with Phase-locked Counter-rotating Rotor Sets</b>

<p dir="ltr">Proposes and analyzes an asymmetric inertial propulsion concept using phase‑locked, counter‑rotating rotor pairs that produce time‑asymmetric internal forces; a phase‑selective couple/decouple mechanism channels strong (constructive) force lobes to an external reaction path while isolating weaker (destructive) lobes. Presents a force and energy model with per‑cycle impulse estimates, conservation and momentum bookkeeping, timing/latency requirements for fast couplers, candidate coupler architectures, and practical design constraints. Validates feasibility with a four‑wheel ground stick–slip prototype and a low‑friction payload push test plan, plus instrumentation, success criteria, and an energy audit to quantify performance and losses.</p>
