SAS Ballast System (WTC Technology):Engineered by David Merriman III, this system is based on an airpump and is a hybrid of the low-pressure and compressed air ballast systems. Todive, the vent valve is opened by a servo and air escapes, submerging themodel. To surface, the air pump is turned on, which draws air from the drycompartments of the WTC Water is displaced in the ballast tank and the modelbegins to surface. Once the snorkel assembly breaches the surface, its valve isopened, equalizing pressure in the cylinder and drawing air from the surface tocomplete blowing the tank until empty and the model returns to the fullsurfaced trim. A one-way float valve ensures that water is not inadvertentlypumped into the cylinder. An emergency gas backup is easily fitted to the servoassembly, offering additional safety during operation. 该系统由David Merriman III 设计。该系统基于气泵，是低压空气压载系统和压缩空气压载系统的混合体。下潜时，排气阀由舵机打开，空气逸出，淹没模型。上浮时，打开气泵，从WTC 的干燥隔间抽取空气。压载舱中的水被挤出，模型开始上浮。一旦通气管浮出水面，阀门就会打开，平衡WTC 中的压力并从表面吸入空气以完全排空压水舱，模型完全浮出水面。单向浮球阀用来保证水不被泵入WTC 。舵机组件上可轻松安装应急备用气体（GAS 系统），在操作过程中提供额外的安全性。
Pros: Includes the benefits offered bythe compressed air and low-pressure vent systems. Emergency gas backupavailable. No need for gas in standard configuration. 优点：包括压缩空气和低压排气系统提供的好处。提供紧急备用气体。标准配置中无需高压气罐。 Cons: More complicated than othersystems. Air pump is slower for large ballast tanks. 缺点：比其他一些系统更复杂。对于大型压载舱，气泵速度较慢。 Non-electrical mechanisms associated：SNORKEL ASSEMBLY: This item comes with the 3.5 SKIPJACK SDand is detailed later on. A key element to the SAS ballast sub-system in thatit works to block off water from getting into the induction line once the saildunks underwater and opens again when the sail broaches the surface. When thesnorkel head-valve shuts, the LPB is forced to draw air from within the SD’sinterior. SAS压载子系统的一个关键元件，一旦舰桥在水下浸泡，它就会阻止水进入进水管，并在其露出水面时再次打开。当通气管头阀关闭时，LPB被迫从WTC内部吸入空气。 SAFETY FLOAT VALVE(安全浮阀): This float-operated valve steps in toisolate the SD’s interior from flooding should water get into the inductionline. 如果水进入进水管路，该浮子机械阀可将WTC的内部与水隔离。 FOUR-POINT MANIFOLD(四点歧管): A cast resin manifold where the snorkel,and some of the discharge and induction flexible hose elements gather at acentralized point atop the SD cylinder. The manifold is where LPB discharge airenters the ballast tank. 一种铸造树脂歧管，通气管以及一些排放和感应软管元件聚集在WTC气缸顶部的集中点。歧管是LPB排放空气进入压载舱的地方。 VENT VALVE: This servo-actuated valve dumps the airwithin the ballast tank when the command is given to flood. At all other times,the vent valve is in the closed position. 当发出溢流命令时，这种舵机驱动的机械阀门倾倒压载舱内的空气。否则，排气阀始终处于关闭位置。 Electrical mechanisms associated：LBPLPB (low pressure blower) 这是一种经过改良的隔膜泵，通过在泵内加一层橡胶，保证在有压力的情况下泵的两孔不互通。
