Scaling laws and model design techniques for increasing fidelity of underwater simulation of zero-g and partial-g environments are described; emphasis is on role that hydrodynamic mass plays in underwater simulation of accelerating bodies; proposed model design technique, wherein model mass plus hydrodynamic mass equals mass being simulated, results in more accurate acceleration response to given applied force; techniques also apply to rotational motions wherein analogous parameters are moment of inertia, hydrodynamic moment of inertia, and rotational damping; tests results employing these principles compared favorably with motions which would have occurred in space.
