A Study of Maneuverability Prediction of Air Cushion Vehicles Using Virtual Captive Model Test Results

다국어 초록 (Multilingual Abstract)

The maneuverability of an Air Cushion Vehicle (ACV) is a critical aspect of its performance, affecting its stability, control, and overall operational effectiveness. Despite the operational complexity due to the interaction of aerodynamic and hydrodynamic forces, significant strides have been made in predicting its maneuverability. This paper discusses the maneuverability prediction of ACV based on virtual captive model tests. Hydrodynamic and aerodynamic forces on ACV's were assessed through computational fluid dynamics (CFD) calculations. Subsequently, a maneuvering simulation considering these forces was performed. The paper explores the results of aerodynamic and hydrodynamic forces during static tests such as static drift and circular motion tests. Additionally, the maneuverability performance in turning and zig-zag tests was evaluated. Furthermore, these performances were compared with the maneuvering standards suggested by the International Maritime Organization (IMO). The outcomes from the virtual captive model tests have significantly enhanced the predictive accuracy of ACV maneuverability, contributing to refined design and operational strategies.
