Z4DP: Hydrodynamic Interpretation of Astrodynamic Anomalies - Kinematics of Bodies and Shielding in a Continuum Model

This paper presents an alternative analytical framework for resolving selected kinematic deviations in local space. Observed astrodynamic anomalies, which often require the introduction of ad hoc parameters within standard models, are examined here through the lens of superfluid continuum mechanics (the Z4DP model). The study demonstrates that conceptualizing cosmic space as a compressible hydrodynamic medium offers a consistent unification for four independent phenomenological events: 1) Asymmetric velocity changes during the Galileo spacecraft flybys, 2) Constant deceleration of the Pioneer probes, 3) Non-gravitational acceleration of the interstellar object 11/'Oumuamua on its escape trajectory, and 4) Deviations in gravitational acceleration during solar eclipses (the Allais effect). The results indicate that the applied hydrodynamics of the vacuum exhibits a high degree of correlation with empirical telemetry data.
