“…Aspects of the evolution operator that correspond to the linear equations' spectral features are also examined as the system approaches its stability criteria. The influence of a solid cylindrical body on the surface of a cylindrical cavity is discussed in [6] for gaps between the cavity surface and the body surface that are zero and nonzero. Hydrodynamic and kinematic properties are obtained.…”

The rotational motion of a charged rigid body (RB) is examined. The RB has a spherical cavity that contains an incompressible viscous liquid. The influence of a gyrostatic moment (GM), constant torques at the body-connected axes, and the action of the torque of a resistant force, due to the shape of the liquid, are considered. Assuming the liquid has a sufficiently high velocity, the Reynolds number does indeed have a small value. The regulating system of motion is derived in an appropriate formulation through Euler's equations of motion. The averaging method is used to approach a suitable form of the motion's governing system. In addition to using Taylor’s method to reach a solution for the averaged equations of motion of the RB, some initial conditions are considered to approach the required results. The asymptotic approach of the averaged system besides the numerical analysis enables us to obtain the appropriate results of the problem. To draw attention to the beneficial effects of the different values of the body’s parameter on the motion's behavior, these results are graphed through a computer program along with the associated phase plane curves. These diagrams illustrate the influence of several values respected to the GM, charge, body-constant torques, and resistive force torque. The stability of the RB's motion has also been discussed through the represented phase plane diagrams. These results are viewed as a generalization of prior ones, which have been reported for the scenario of an uncharged body or the absence case of the GM. The significance of the obtained results is due to its numerous real-world applications in life, such as for spaceships and wagons carrying liquid fuel.

“…The increase in the mass of the projectile can reduce the deviation of the projectile trajectory, and the increase in the diameter of the supercavity will increase the deviation of the trajectory. Using a water tunnel, the literature [3] studied the hydrodynamic problem of a cylindrical vehicle tail when sliding inside the cavity.…”

Currently, the supercavitating projectiles mostly rely on experience or experimental results to test the shape of the projectile; however, the cost of the experiment is relatively high, and there is no specific criterion to judge whether the underwater projectile is stable. To solve the aforementioned problems, we study the motion stability and establish motion equations for supercavitating projectiles. Through theoretical analysis and simulation calculations, the optimal center of mass position is designed to optimize the motion performance of underwater supercavitating projectiles. We think this work can provide theoretical support for the optimal design of underwater supercavitating projectiles.
