3.0 INTERFACE DEFINITION

3.1 GENERAL DESCRIPTION

3.1.1 INTERFACE DESCRIPTION

The Node 2 to USL mated on−orbit configuration is shown in Figure 3.1.1−1. The structural and mechanical interface is at the plane between the Active Common Berthing Mechanism (ACBM) of the USL and the Passive Common Berthing Mechanism (PCBM) of the Node 2 as documented in SSP 41148. The interface between the Node 2 and the USL to the Common Berthing Mechanism (CBM) is documented in SSP 41004. The electrical utility interface plane is between the bulkhead at the USL and ACBM as shown in Figure 3.1.1−1. The fluid utility interface plane is between the bulkhead of Node 2 and the PCBM as shown in Figure 3.1.1−1.

3.1.3 ENGINEERING UNITS AND TOLERANCES

Unless otherwise noted herein, all dimensions are in the English system of inch, pound, and second units. Unless noted otherwise angular tolerances are + 0.1° and linear tolerances are as shown in Table 3.1.3−1.

3.2 STRUCTURAL/MECHANICAL INTERFACE

3.2.1 GENERAL

Node 2 structurally attaches to the USL via a CBM. The CBM has two halves each of which are attached to the pressure shells of each element in accordance with SSP 41004. Node 2 contains the PCBM and the USL contains the ACBM. The bulkhead of each element provides the routing of utilities around the clear passage envelope and within the CBM volume.

3.2.2 UTILITY PENETRATIONS

The assigned penetrations and reference designations for the Node 2 aft bulkhead are shown in Figure 3.2.2−1. The assigned penetrations and reference designations for the USL’s forward bulkhead are shown in Figure 3.2.2−2. The centerline address and hole detail for each utility penetration on the bulkhead is in accordance with Table 3.2.2−1 and Table 3.2.2−2.

3.4 ELECTRICAL INTERFACE

3.4.1 ELECTRICAL CONNECTIVITY

The electrical interface between Node 2 and the USL consists of a series of electrical jumpers connected between each element bulkhead. ASI/Alenia is responsible for the Node primary structure, including the installation of the NASA GFE electrical feedthrough receptacles in the bulkhead. The electrical interface plane resides between the electrical jumper assembly forward and aft jumper plug and the USL and Node 2 bulkhead feedthroughs receptacles. Line losses associated with the vestibule jumpers are allocated to Node 2. Another interface exists between the Node 2 bulkhead feedthroughs receptacles and the internal outfitting plug installed by ASI/Alenia.

3.4.1.1 DETAILED ELECTRICAL INTERFACE

The bulkhead feedthrough receptacles for the Node 2 and USL are identical in part number and pin definition unless noted otherwise in the pin function tables. The mating plugs on either side of the bulkheads are identical unless noted otherwise in the pin function tables. Unless noted otherwise all shields are attached to connector back shell.

3.4.1.2 ELECTRICAL JUMPER DETAIL

Each electrical jumper is a cable assembly consisting of two electrical plugs reference designated in numerical accordance with its mating pressure shell penetration connector on the interfacing element. The electrical jumper assembly is NASA GFE and has a part number and reference designator as defined in Table 3.2.2−2, Avionics Interface Detail Definition.

3 − 14

Control of the detailed electrical interface consists of identifying the particular receptacle/plug pair, configuration, location, part number and functionality. The details of these controlling parameters are shown in Table 3.2.2−2, Figure 3.4.1.2−1 thru Figure 3.4.1.2−20.
