1.0 INTRODUCTION

1.1 PURPOSE AND SCOPE

The purpose of this Interface Control Document (ICD) is to define and control the implementation of the physical and functional interfaces between Pressurized Mating Adapter (PMA) 2 and Resource Node 2. Part 1 of this ICD contains the design requirements for this interface; Part 2 contains the design solutions for those requirements.

The scope of this section of the document is limited to the physical and functional interfaces between Node 2 and PMA 2. All other PMA 2 and PMA 3 interfaces with pressurized elements that occur during build up of the Space Station are documented in individual appendices of this ICD as noted below.

See Appendix B for PMA 2 to USL interface definition.

See Appendix C for PMA 2 to Node 1 interface definition.

See Appendix D for PMA 3 to Node 1 interface definition.

See Appendix E for PMA 3 to Node 3 interface definition.

1.2 PRECEDENCE

This ICD is prepared in response to the bilateral interface requirements established in SSP 42097 PMA 2&3 to Pressurized Elements Part I ICD. In the event of a conflict between this document and SSP 42097 PMA 2&3 to Pressurized Elements Part I ICD, the Part I ICD will take precedence.

1.3 RESPONSIBILITY AND CHANGE AUTHORITY

The responsibility for assuring the definition, control, and implementation of the interfaces identified in this document is vested with the NASA ISS Program Office. This document will be formally approved and controlled in accordance with the provisions of document SSP 30459, International Space Station Program Interface Control Plan.

3.0 INTERFACE DEFINITION

3.1 GENERAL

Unless otherwise noted, none of the drawings contained in this ICD are to scale.

3.1.1 INTERFACE DESCRIPTION

The interface description here applies to the PMA 2 / Node 2 interface.

The PMA 2 to Node 2 mated on orbit configuration is shown in Figure 3.1.1–1 PMA 2 to Node 2 On Orbit Configuration.

The element to element structural and mechanical interface is between the CBM halves as shown in Figure 3.1.1–2, PMA 2/Node 2 Interface Planes. The external utility interface plane is between the connector plug on the end of the jumper from PMA 2 and the receptacle located on the Node as shown in Figure 3.1.1–2. The internal utility interface plane for IMV, O2/N2 and fuel cell water is at the Node 2 bulkhead where the PMA attaches as shown in Figure 3.1.1–2.

3.1.2 INTERFACE RESPONSIBILITIES

NASA is responsible for development of the PMA. ASI has responsibility for development of Node 2.

3.1.3 ENGINEERING UNITS AND TOLERANCES

Unless otherwise noted herein, all dimensions in this document are shown in English system of inch pound (IP) units. Implied tolerances on linear dimensions are defined in Table 3.1.3–1, Linear Tolerances. Angular Tolerances are shown in Table 3.1.3–2, Angular Tolerances.

Angular Tolerances are shown in Table 3.1.3–2, Angular Tolerances. Linear tolerances on metric dimensions are derived from English measurements and tolerances as defined in ASTME 380, Standard Practice for Use of the International System of Units (SI) (The Modernized Metric System), Section 4.5.

3.2 STRUCTURAL/MECHANICAL INTERFACES

3.2.1 COMMON BERTHING MECHANISM INTERFACES

PMA 2 and Node 2 are structurally/mechanically attached using an active and passive common berthing mechanism (CBM) in accordance with the requirements and design criteria shown in SSP 41148, ACBM to PCBM ICD. The active common berthing mechanism is located on the Node 2 side of the interface and is attached to the Node pressure shell in accordance with SSP 41004, Common Berthing Mechanism to Pressurized Element ICD. The ACBM connector reference designators and bulkhead feedthrough locations are shown in Figure 3.2.1–1, Node 2 Forward Bulkhead ACBM Connector Locations and defined in Table 3.2.1–1, Node 2 Forward Bulkhead ACBM Connector Locations. The power and data do not cross the PMA2/Node 2 interface. The passive common berthing mechanism is located on the PMA 2 side of the interface and is attached to PMA 2 in accordance with SSP 41004.

3.3 INTERNAL UTILITY INTERFACES

3.3.1 INTERMODULE VENTILATION

The flex duct transferring IMV air between PMA 2 and Node 2 has a V–Band interface flange on the end of the duct that is structurally attached to the Node bulkhead starboard IMV feedthru flange. These are attached using a V–Band coupling (MS27115–21R) provided at the Node bulkhead by Boeing–Huntsville. The V–Band coupling that is originally used to secure the IMV port cap is reused to make this duct connection after the cap is removed.

The flex duct located in PMA 2 is shown in Figure 3.3.1–1, PMA 2 IMV Flex Duct. The PMA IMV duct flange detail is shown in Figure 3.3.1–2, PMA IMV Jumper Duct Flange Cross Section. When the PMA flexible duct connects to the Node 2 bulkhead IMV feedthru, it connects to an integral bulkhead V–band flange as shown in Figure 3.3.1–3, Node Integral Bulkhead Feedthru Flange Cross Section. The attached V–Band flange and coupling is shown in Figure 3.3.1–4, IMV V–Band Flange Interface Detail.

IMV air is transferred from the PMA to Node 2 through the flex duct described above. Air is returned to the PMA through the open hatch.

3.3.2 OXYGEN / NITROGEN RECHARGE

Recharge oxygen and nitrogen is transferred from PMA 2 to Node 2 through flex hoses located in the PMA that attach to the Node 2 bulkhead with gammah fittings. The attachment location is shown in Figure 3.3.2–1, Fluid Feedthru Locations and Figure 3.3.2–2 Fluid Feedthru Centerline Locations. The interface detail is shown in Figure 3.3.2–3, O2/N2 Interface Detail, Figure 3.3.2–4, O2/N2 Threaded Feedthrough Assembly Interface Details, and Table 3.3.2–1, Fluid Interface Detail.

3.3.3 FUEL CELL WATER

Fuel cell water is transferred from the Orbiter to Node 2 via a dragthru flex line that attaches to the Node 2 bulkhead. The attachment location is shown in Figures 3.3.2–1 and 3.3.2–2. The interface detail is shown in Figure 3.3.2–3 and Figure 3.3.3–1, Fuel Cell Water Self–Sealing Quick disconnect Assembly Interface Detail, and Table 3.3.2–1.

3.3.4 POWER SCAR

The Node 2 forward bulkhead has 2 3KW power feeds as shown in Figure 3.2.1–1. The connector locations are defined in Table 3.3.4, Node 2 Forward Bulkhead Connector Detail. The two power circuits, Node 2 FWD A and Node 2 FWD B, do not interface with PMA 2.
