    摘要： A debris deflector protects an underwater vehicle's control. surface whilentroducing little or no flow disturbance around the control surface. The deflector extends outward from the vehicle to peninsulate the control surface. The deflector's cross-section is defined by a wedge shape subtended by an arc with the apex of the wedge shape always pointing towards the control surface.

    摘要： A method is provided for navigating a vehicle. Waypoint exclusion zones areefined as circles whose centers are known-position waypoints. The vehicle is steered along a path that is tangential to the "current" waypoint exclusion zone. This path that is maintained until a relative bearing between the vehicle and a center of the current waypoint exclusion zone is at least 90.degree. if the path is left of the center of the current waypoint exclusion zone, and at most -90.degree. if the path is right of the center of the current waypoint exclusion zone. When either of these conditions is met, the vehicle is located along the circle of the current waypoint exclusion zone. The vehicle is then advanced along the circle of the current waypoint exclusion zone until a heading of the vehicle matches a heading of a path that: is tangential to the "next" waypoint exclusion zone. When the heading of the vehicle matches the heading of the path that is tangential to the next waypoint exclusion zone, the next waypoint exclusion zone becomes the current waypoint exclusion zone for carrying out the steering, maintaining and advancing of the vehicle.

    摘要翻译： 提供了一种用于导航车辆的方法。 航路点禁区被定义为其中心是已知位置航路点的圆。 沿着与“当前”航路点排阻区相切的路径转向车辆。 如果路径留在当前航路点禁区的中心，直到车辆与当前航路点禁区的中心之间的相对方位相对保持的路径至少为90°，如果路径为-90° 是当前航路点禁区的中心。 当满足这些条件中的任何一个时，车辆沿着当前航路点禁区的圆圈定位。 然后车辆沿着当前航路点禁区的圆前进，直到车辆的航向与与“下一个”航路点禁区为切向的路径的航向相匹配。 当车辆的航向匹配与下一个航路点排除区相切的路径的航向时，下一个航路点禁区将成为当前的航路点排除区，用于执行车辆的转向，保持和前进。
