The rotational deflection is measured with respect to the hatch Y–Z plane as defined when there is zero pressure differential across the hatch. The stiffness of the hatch is considered negligible and does not contribute to the overall stiffness of the bulkhead.

3.3.3.8 PRESSURE EQUALIZATION VALVE

The pressure equalization valve is a manually operated mechanism, which equalizes the pressure differential across the hatch to approximately zero. The effective hydraulic diameter of the valve is 1.00 (25.4) with a discharge coefficient of 0.65.

3.3.3.9 DIFFERENTIAL PRESSURE GAGE DELETED

3.3.4 HATCH–TO–PRESSURIZED ELEMENTS INTERFACES

The hatch–to–pressurized elements interfaces consist of the pressure seal–to–sealing surface interface and the latch mechanism, seal separation device, and alignment guide–to–bulkhead interfaces.

3.3.4.1 LATCH MECHANISM

The latch mechanism provides pre–loading of the pressure seals and secures the hatch to the pressurized element. The latch mechanism is as shown in Figure 3.3.4.1–1, Hatch Latch Mechanism (Typical). The latches interface with element bulkhead cutouts as shown in Figure 3.3.4.1–2, Element Bulkhead Latch Interface Cutouts, at the locations as shown in Figure 3.3.4.1–3, Element Bulkhead Latch Interface Cutout Locations. The latch mechanism–to–pressurized element interface is as shown in Figure 3.3.4.1–4, Hatch Latch Mechanism–to–Pressurized Element Interface (Profile View).

The kicker plate shown in Figure 3.3.4.1–2 is inserted on the element bulkhead to help alleviate wear–and–tear at the latch mechanism–to–element bulkhead interface. Each kicker plate is designed to withstand a load of 134 lbs over a 0.44 in. long edge with a 0.05 inch radius as shown in Figure 3.3.4.1–5, Kicker Plate Load Application Condition. The kicker plate has a material type of 15–5PHH1025 per AMS5659 with a passivated stainless steel finish.

3.3.4.2 PRESSURE SEALS

Air leakage at the hatch sealing surface is minimized by one–fault tolerant Gask–O–SealTM. The seal is comprised of four (4) identical quarter sections, which are fastened to the element bulkhead. Pressurized element bulkhead dimensions and surface finishes to accommodate the seal are as shown in Figure 3.3.4.2–2, Pressurized Element and Hatch Seal Interfaces. Insert locations to accommodate the seal are as shown in Figure 3.3.4.2–3, Element Bulkhead Seal Insert Locations.

Seal leakage rate is as specified in SSP 41015 Part 1, Paragraph 3.2.1.3.4.1.

3.3.4.3 SEAL SEPARATION DEVICE

The hatch seal separation device (kicker) is an integral part of each hatch latch mechanism. This device separates the pressure seals from the sealing surface by applying a force to the module bulkhead upon rotation of the crank handle when un–latching the hatch.

The seal separation device–to–module interface is as shown in Figure 3.3.4.1–2. The seal separation device is as shown in Figure 3.3.4.3–1, Seal Separation Device.

3.3.5 HATCH TRACK–TO–PRESSURIZED ELEMENTS INTERFACES

Two different track configurations are used, one for axial and another for radial port locations.

Nodes contain both axial and radial port tracks while other pressurized elements contain only the axial port configuration.

A common bracket is used to attach the axial and radial track bottoms to the element bulkhead.

Threaded inserts in the element bulkhead are provided to bolt the common attach bracket in place. The inserts, part number MS51830CA202L, are located as shown in Figure 3.3.5–2.1, Common Attach Bracket Mounting Locations. The common bracket is as shown in Figure 3.3.5–3, Hatch Track Common Attach Bracket.

A different bracket is used to attach the axial port track tops to the element endring. Holes in the endring permit this bracket to be bolted onto the endring at the locations as shown in Figure 3.3.5–3.1, Axial Track Endring Bracket Mounting Locations. The axial track bracket is as shown in Figure 3.3.5–4, Axial Track Endring Mounting Bracket.

The radial port truss tops are attached to the element bulkhead with a third bracket. Threaded inserts identical to those used with the common attach bracket are provided at the bulkhead locations as shown in Figure 3.3.5–4.1, Radial Truss Bracket Mounting Locations. The bracket is as shown in Figure 3.3.5–4.2, Radial Truss Mounting Bracket.

The upper mounting bracket attachment locations for the hatch track assembly to element bulkhead interface are as shown in Figure 3.3.5–4.3, Hatch Track to Element Bulkhead Upper Mounting Bracket Attachment Locations.
