INTERFACE

General Interface Description The HTV is to nominally berth to the nadir port of the Node 2. It can alternately be berthed to the Node 1 Nadir port. The Node 2 Zenith port no longer supports berthing. In this section and other sections of this document, where there is a choice between berthing at Node 1 Nadir or Node 2 Zenith, the Node 1 Nadir port will be used. The Node 2-to-HTV on-orbit configuration is shown in Figure 3.1.1-1, On-orbit Configuration of Node 2 to H-II Transfer Vehicle and the Node 1 to HTV on orbit configuration is shown in Figure 3.1.1-2, On-orbit Configuration of Node 1 to H-II Transfer Vehicle. The USOS-to-HTV utility interface plane is shown in Figure 3.1.1-3, Interface Planes. The USOS to HTV utility interfaces are on the pressure bulkhead at the external feed through connectors of the HTV. The structural and mechanical interface is at the plane between Common Berthing Mechanism (CBM) active and passive halves attaching a Node to the HTV. Dimensions and material characteristics at the CBM to pressurized element interface are in accordance with SSP 41004, Common Berthing Mechanism to Pressurized Elements Interface Control Document. Dimensions and material characteristics at the interface plane between the CBM active and passive halves are in accordance with SSP 41148, Active Common Berthing Mechanism to Passive Common Berthing Mechanism Interface Control Document.

Items used in this interface include: avionics connectors, connector caps, fluid quick disconnects, Intermodule Ventilation (IMV) ducts, V-Band clamps, pressure caps, and close-out panels.

INTERFACE RESPONSIBILITIES

Unless otherwise noted, National Aeronautics and Space Administration (NASA) carries the responsibility for designing to the interface requirements imposed on the USOS portion of this interface and JAXA carries the responsibility for designing to the interface requirements imposed on the HTV portion of this interface.

COORDINATE SYSTEMS

The HTV Reference Coordinate Systems are defined in SSP 30219, Space Station Reference Coordinate Systems and SSP 50438, Part 1.

Coordinates depicted in Table 3.2.1.5-1, Fluid Interface Detail Definition, and Table 3.2.1.6.1-1, Avionics Interface Detail Definition, are referenced from the intersection of the centerlines of the hatch openings of the respective elements and not in terms of the Node Reference Coordinate System.

STRUCTURAL INTERFACE

The HTV with an Exposed Pallet (EP TYPE I, EP-MP or EP Type Li-on battery ORU plus (EP-6B+)) provides interfaces for grapple fixtures (GFs) at the location and orientation specified in Table 3.2.1.3-1, HTV Grapple Fixture Location and Orientation. The Exposed Pallets, themselves, also provide interfaces for GFs at specific locations and orientations. The EP TYPE I and EP-MP for JEM provides interface as specified in Table 3.2.1.3-2, HTV EP TYPE I Grapple Fixture Location and Orientation and Figure 3.2.1.3-1, HTV EP TYPE I Grapple Fixture Locations. The EP-MP for POA provides interface as specified in Table 3.2.1.3-3, HTV EP TYPE III Grapple Fixture Location and Orientation and Figure 3.2.1.3-2, HTV EP TYPE III Grapple Fixture Locations. The EP-6B+ provides interface as specified in Table 3.2.1.3-5, HTV EP-6B+ Grapple Fixture Location and Orientation and Figure 3.2.1.3-4, HTV EP-6B+ Grapple Fixture Locations.

When the disposal of HTV Cargo Attachment Mechanism (HCAM) type EF payloads is required, the EP TYPE I and EP-MP for JEM provides interface as specified in Table 3.2.1.3–4, HTV EP Micro Fixture Location and Orientation for HTV Exposed Facility Unit (HEFU) actuation by SPDM and Figure 3.2.1.3–3, HTV EP Micro Fixture and Visual Indicator Locations for HEFU actuation by SPDM.

The HTV coordinate system is as defined in SSP 50438 Part 1. The Grapple Fixture Axis System (GFAS) is defined in SSP 42004, Mobile Servicing System (MSS) to User (Generic), Interface Control Document, and Part 1, Section I for Flight Releasable Grapple Fixture (FRGF) and Section N for Power & Video Grapple Fixture (PVGF), and Section C for Micro Fixture.

Orientation of each GF is specified in a pitch–yaw–roll Euler sequence from the HTV coordinate system to GFAS.

In using an Euler sequence, align the GFAS with the HTV reference frame in attitude, (the position is defined as X, Y, Z). Rotate the GF about the GFAS Y axis by the value given as pitch. Rotate the GF about the new GFAS Z axis by the value given as Yaw. Finally rotate the GF about the new GFAS X axis by the value given as Roll.

ELECTRICAL INTERFACE

ELECTRICAL CONNECTIVITY

The electrical interface between the USOS and the HTV consists of a series of electrical jumpers connected between each element bulkhead as shown in Figure 3.2.1.6.1-1, Node Element to HTV Generic Electrical Utility Interface. The Node 1 to HTV electrical interface resides between the Node 1 provided electrical jumper assembly connector plug and the HTV bulkhead feedthrough receptacle. The Node 2 to HTV electrical interface resides between the Node 2 provided electrical jumper assembly connector plug and the HTV bulkhead feedthrough receptacle.

Figures in Sections 3.2.1.6.1 for Node 1 Nadir is for HTV clocked with ULC opening facing in the aft (-X) direction.

Each electrical jumper assembly is a cable assembly terminated into two electrical plugs, each reference designated in numerical accordance with its mating pressure shell penetration connector (on the interfacing element).

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 3.2.1.6.1-1, Node 1 and Node 2 Power and Avionics Interface Detail Definition, Figure 3.2.1.6.1-1 Node Element to HTV Generic Electrical Utility Interface, Figure 3.2.1.6.1-2, Standard Avionics Penetration Detail, Figure 3.2.1.6.1-3 Detailed Electrical Description Of Node 1 Nadir Bulkhead J103 And HTV Bulkhead J3, Figure 3.2.1.6.1-4, Detailed Electrical Description of Node 1 Nadir Bulkhead J106 and HTV Bulkhead J6, Figure 3.2.1.6.1-5, Detailed Electrical Description of Node 1 Nadir Bulkhead J115 and HTV Bulkhead J15, Figure 3.2.1.6.1-6 Detailed Electrical Description Of Node 1 Nadir Bulkhead J118 And HTV Bulkhead J18, Figure 3.2.1.6.1-7, Detailed Electrical Description of Node 2 Nadir Bulkhead J115 and HTV Bulkhead J15, Figure 3.2.1.6.1-8, Detailed Electrical Description Of Node 2 Nadir Bulkhead J118 And HTV Bulkhead J18, Figure 3.2.1.6.1-9, Detailed Electrical Description of Node 2 Nadir Bulkhead J106 and HTV Bulkhead J6, Figure 3.2.1.6.1-10, Detailed Electrical Description of Node 2 Nadir Bulkhead J103 and HTV Bulkhead J3, Figure 3.2.1.6.1-11, Detailed Electrical Description of Node 2 Zenith Bulkhead J65 and HTV Bulkhead J15, Figure 3.2.1.6.1-12, Detailed Electrical Description of Node 2 Zenith Bulkhead J58 and HTV Bulkhead J3, Figure 3.2.1.6.1-13, Detailed Electrical Description of Node 2 Zenith Bulkhead J56 and HTV Bulkhead J6 for N2-2 Bus A Interface, Figure 3.2.1.6.1-14, Detailed Electrical Description of Node 2 Zenith Bulkhead J68 and HTV Bulkhead J18 for N2-2 Bus B Interface, Figure 3.2.1.6.1-15, Detailed Electrical Description of Node 2 Zenith Bulkhead J56 and HTV Bulkhead J6 for N2-1 Bus A Interface, and Figure 3.2.1.6.1-16, Detailed Electrical Description of Node 2 Zenith Bulkhead J68 and HTV Bulkhead J18 for N2-1 Bus B Interface. For Node 2 Zenith, there are two potential 1553 interfaces: one with N2-2 bus and another with N2-1 bus. Only one interface can be connected at a time, nominally the N2-1 bus (W7950 and W7951 in Figures 3.2.1.6.1-14 and 3.2.1.6.1-15). The N2-2 bus is considered a secondary option (W4012 and W4013 in Figures 3.2.1.6.1-12 and 3.2.1.1.6-14) since the N2-2 bus is primarily for N2 Nadir port. Unless noted otherwise all shields are attached to the connector backshells.

ELECTRICAL BONDING

Electrical bonding of HTV to Node will be accomplished via proper bonding of the intermediate interface sections, namely HTV to PCBM bonding interface, PCBM to ACBM bonding interface and ACBM to Node bonding interface. PCBM to ACBM bonding interface will implement class H bonding. HTV to PCBM and ACBM to Node bonding interface will be in accordance with SSP 41004. These bonding interfaces will be designed to conduct 200 A with a duration of 500 ms without creating a thermal or electrical hazard. In detail:

- HTV to PCBM bonding interface will be performed as per SSP 41004, Part 1 and Part 2.

- PCBM to ACBM bonding interface will be performed as per SSP 41148.

- ACBM to Node interface will be performed as per SSP 41004, Part 1 and Part 2.

Light specification

(1) Acquisition Lights The Acquisition Lights provide visual contact at 1000 m in a condition of total darkness and will be a flashing light.

(a) Intensity: The power of a blinking light between +/- 80 degrees is inside of the following region under the condition that on-time duration is shorter than 120 ms.

Note that effective intensity of a blinking light is determined by the Blondel-Rey Equation.

The power of the blinking light is shown in Figure 3.2.1.7.3-1, Acquisition Lights Power from Centerline

figure 3.2.1.7.3-1 acquisition lights power from centerline

(2) Orientation Lights The Orientation Lights provide visual information of attitude and orientation in a condition of total darkness and will be a running light.

figure 3.2.1.7.3-2 orientation lights intensity from centerline prox link communication zone (cz) To be supplied (TBD) berthing box data The HTV maintains the relative position of the FRGF in Inner Capture Box (ICB) prior to SSRMS capturing operation. The HTV FRGF remains within the Middle Grapple Box (MGB) during free drift for SSRMS capturing. The HTV FRGF remains in Total Capture Box (TCB) during SSRMS deceleration to a complete stop. The berthing box data includes the location and dimensions of the boxes. The berthing box depends on the ISS DTEA attitude of the respective HTV mission. The typical examples of the berthing box data are defined in Table 3.2.1.9-1, Berthing Box Data, with the condition of the ISS DTEA attitude.
