Reconstruction of Rotational Dynamics and Prediction of Vacuum Propellantless Thrust Based on FQ Fluid Occlusion Pressure Difference

English Abstract Classical mechanics explains the mechanical effects of rotational systems centered on the law of conservation of angular momentum, the classical fluid momentum theorem, and aerodynamics, which can accurately describe the motion laws of macroscopic low-speed rotating objects. However, it fails to reveal the underlying physical essence of rotational force bearing, gyroscopic directional stability, and fluid thrust effects. Meanwhile, its theoretical system is highly dependent on macroscopic media such as air and conventional fluids, resulting in inherent application limitations. Based on the core axioms of the FQ Gravitational Pressure Unified Field Theory, this paper introduces the physical scenario of dynamic time-domain occlusion to reconstruct the underlying mechanism of rotational dynamics. Stationary substances present a hollow sieve-like static occlusion state, allowing graviton fluids to penetrate most of the material structure. High-speed rotating objects can smooth the microscopic hollow structure in the time dimension, forming an equivalent continuous dynamic occlusion surface. Through substituting the basic formulas of FQ background fluid pressure, density and wave velocity, a rigorous mathematical derivation of the rotational thrust model is completed. It is verified that the FQ dynamic occlusion thrust formula is completely mathematically isomorphic with the classical aerodynamic lift formula, uniformly explaining the symmetric rotational directional stability of gyroscopes and the asymmetric rotational thrust mechanism of propellers and tires. Based on the theoretical model, a falsifiable crucial experimental prediction is proposed: in a high-vacuum environment without air media, rotating structures with inclination angles can still generate weak net thrust relying on the global graviton fluid background. This research provides a novel underlying theoretical support for propellantless propulsion technology, realizing the compatibility, reconstruction and transcendence of the classical rotational mechanics system.
