The ultra-high-speed aerodynamically alleviated marine vehicle (AAMV) is an unmanned surface vehicle (USV) with the advantages of fast speed, shallow draft, strong wind and wave resistance and long voyage, which fills the gap between high-speed aircrafts and low-speed surface vehicles. To explore the influence of waves on the motion characteristics of the ultra-highspeed AAMV, numerical research on stability of the ultra-high-speed AAMV at different speed and different sea states is carried out. The stability mathematical model of the ultra-high-speed AAMV is established based on the small disturbance linearization theory, and the stability of the vehicle is divided into longitudinal stability and lateral stability. Numerical results show that the ultra-high-speed AAMV shows good longitudinal and lateral stability at cruise speed. At the cruising phase, the pitch angle response, the roll angle response, and the heave response under sea state 5 are 0.210°, 0.0229° and 0.0734m, respectively. With the increase of speed, the aerodynamic force of the ultra-high-speed AAMV gradually increases, and the effect of aerodynamic alleviation is also enhanced accordingly, which greatly weakens the influence of waves on motions. The effect of aerodynamic alleviation can effectively improve the stability of the ultra-high-speed AAMV in waves.

The ultra-high-speed aerodynamically alleviated marine vehicle (AAMV) is a high-performance vessel that combines a hydrodynamic configuration and an aerodynamic wing to reduce wave-making resistance during the high-speed planing phase. The forces of the AAMV exhibit strong nonlinear and water–air coupling characteristics, resulting in particularly complex motion characteristics. This paper presents a longitudinal and lateral stability model of the AAMV, which considers the effects of aerodynamic alleviation. Additionally, a numerical model of wind and wave turbulence forces is established, which considers viscous correction based on the potential theory. Finally, the effect of wind and wave turbulence forces on the motion stability of the AAMV under regular and irregular waves is analyzed by numerical solution. The simulation results demonstrate the influence of these disturbance forces on the stability of the AAMV under different sea states. The motion parameters of the AAMV exhibit a pronounced response to changes in sea state level. The aerodynamically alleviated effect is enhanced as speed increases, and the influence of winds and waves on the AAMV is greatly weakened, reducing the possibility of instability. During the cruising phase under class V sea state, the pitch, roll, and heave response are 0.210°, 0.0229°, and 0.0734 m, respectively. This effect can effectively improve the motion stability of the AAMV in winds and waves.
