Configuration Optimization of Supercavitating Underwater Vehicles With Maneuvering Constraints

A survey on tracking control of unmanned underwater vehicles: Experiments-based approach

“…waves, currents, etc.) Ahn et al (2010). For this reason, even the well-know adaptive control schemes may suffer a lot from the changes caused by these disturbances; furthermore, the hydrodynamic estimation tools are expensive, slow, and mostly not available to low-cost UUVs' designers Makavita et al (2019).…”

Design Methodology of Conical Section Shape for Supercavitating Vehicles considering Auto-Oscillation Characteristics

“…Among these, the unique characteristics of the cavity/vehicle system comprise the main factor in resolving these issues. e cavity/vehicle system is complex due to the time-delay effect of the supercavity and conic-like self-excited oscillation of the vehicle [15]. e recent literature also identifies outstanding issues associated with the cavity/vehicle system, as well as the inherent instability motion characteristics of SVs.…”

“…e authors of the present work also discovered the intrinsic conic-like oscillation in the motion of SVs [21] and pointed out that conic-like oscillation is attributed to the occurrence of the tail-slap motion in the vertical and horizontal planes and the steady phase difference. e basic configuration of the vehicle itself is still the major question concerning maneuvering SVs [15]. Limited investigations have been performed on configuration of SVs.…”

“…e results from the aforementioned two studies show promising agreement. Ahn et al [15] optimized the configuration and nominal operating speed of an SV by integrating several operational requirements in the optimization process. Kawakami and Arndt [28] experimentally investigated the artificial supercavitation behind a sharp-edged disk for various model configurations.…”
