3.0 INTERFACES

3.1 General

3.1.1 Interface Description

The interfaces specified herein are applicable to the WHC and Node 3. The WHC is a single rack system that will be located in NOD3P4. For reference, the location is designated by its orientation as defined by the Node 3 baseline shown in Figure 3.1.1-1, WHC Node 3 Location. Node 3 will provide aisle atmospheric air, potable water, electrical power, data, and structural/mechanical interfaces at the rack location. The WHC will provide health and status data, pre-treated urine, return air and structural/mechanical interfaces. The functional interface diagram is shown in Figure 3.1.1-2, Node 3 to WHC Functional Interface Diagram.

Figure 3.1.1-1 WHC Node 3 Location

Figure 3.1.1-2 Node 3 to WHC Functional Interface Diagram

3.1.1.1 Waste & Hygiene Compartment Description

The WHC is for providing crew privacy while performing daily hygiene functions. The primary functions of the WHC are to provide an area for crew cleansing of hands, face and partial body, and support the collection of human metabolic waste. The WHC will consist of a Rocket Space Corporation Energia (RSCE)-provided АСУ and К integrated by the Boeing Company into a NASA-provided Refrigerator/Freezer Rack (RFR).

The WHC system will interface with the Regenerative Environmental Control and Life Support (R-ECLS) Water Recovery System (WRS) to allow for automatic transfer of pre-treated urine to the Urine Processor Assembly and to enable pre-treated urine processing and the production of potable water and oxygen. Additionally, the WHC will integrate with the United States (US) potable/fuel cell water supply to allow for automatic flush water filling and the Urine Monitoring System (UMS). The UMS provides accurate measurement of urine void volume, specific gravity, and provides the capability to withdraw representative samples with minimal additional crew time for substantial science/crew health data.

3.1.1.2 Node 3 Description

The Node 3 is a pressurized element used as a berthing node for ISS elements and provides functions for waste management, water reclamation, urine processing and other vital ISS functions.

3.1.2 Interface Responsibilities

3.1.2.1 Responsibility for Waste & Hygiene Compartment

Unless otherwise noted herein, the Lyndon B. Johnson Space Center (JSC), under agreement with the ISS Program Office, has the responsibility for designing the WHC to the interface requirements herein.

3.1.2.2 Responsibility for Node 3

Unless otherwise noted herein, European Space Agency (ESA) has the responsibility for designing Node 3 to the interface requirements herein.

3.1.2.3 Responsibility for Interconnect Cabling/Tubing/Connectors

Node 3 is responsible for providing interconnecting cabling, tubing, female fluid connectors and plug power/data connectors to the WHC utility interface locations.

3.1.3 Coordinate Systems

The coordinate system applicable to the Node 3 WHC is as defined in SSP 41017, Rack to Mini Pressurized Logistics Module Interface Control Document, Part 2, paragraph 3.1.3. The origin of the Node 3 WHC coordinate system is Point A of the NOD3P4 rack bay.

3.1.4 Engineering Units, Tolerances and Conversions

3.1.4.1 Engineering Units and Tolerances

Dimensions in this document are shown in the English (inch, pound, second) system of units followed by the equivalent International System (SI) value in parenthesis. Measurements may be verified in either system of units.

3.1.4.1.1 Tolerances

Linear tolerances on English dimensions are as indicated in Table 3.1.4.1.1-1, Linear Tolerances. Linear tolerances on metric dimensions are derived from English measurements and tolerances as defined in ASTM E380, Standard Practice for Use of the International System of Units (The Modernized Metric System), section 4.5. Angular tolerances are ± 0.1° on all angles unless otherwise stated.
