Extract

When a hovercraft travels at forward speed, the change in ambient pressure due to the airflow around the vehicle affects the forces experienced by the air cushion and hence, the static and dynamic stability of the vehicle. Such changes are likely to be especially important for a tracked hovercraft entering, or operating within, a tunnel. Knowledge of their magnitude is important in determining the smallest, and hence cheapest, acceptable tunnel.
