A Theoretical Asymmetric Inertial Propulsion System with Phase-locked Counter-rotating Rotor Sets

This version corrects and replaces the previous manuscript posted on May 27, 2025. It includes updated calculations for impulse and energy, clarifies assumptions related to continuous power input and phase asymmetry, and corrects the earlier mischaracterization of axial impulse-now properly described as in-plane (radial) impulse. This paper presents a theoretical propulsion system that generates net thrust in a closed system without expelling mass. The design incorporates two phase-locked, counter-rotating rotor sets mounted on a free-floating frame. Each rotor set contains a fast and a slow rotor with matched centripetal force output but staggered timing, producing alternating constructive and destructive centripetal force phases. Analytical calculations show that asymmetric force alignment over time yields a net impulse per cycle. Energy and momentum conservation are addressed through rotational energy depletion and constructive-phase isolation. While experimental validation is pending, the concept may represent a novel class of inertial propulsion suitable for general and space applications. Numerous prior attempts at propellantless propulsion have failed under critical scrutiny; this manuscript reemphasizes compliance with conservation laws through the lens of inertial phase asymmetry and encourages objective technical evaluation over presumption.
