A Pressurized Mating Adapter (PMA) is a component used on the International Space Station (ISS) to convert the Common Berthing Mechanism (CBM) interface used to connect ISS modules to an APAS-95 spacecraft docking port.

2023年1月14日 · Three PMAs are untilised at the ISS - one for connecting the Russian with the american segment and two to allow dockings of the Shuttle and later Orion spacrafts. PMA 1 connects permanently the aft hatch of Node 1 with the Zarya module.

2017年6月17日 · There are three PMAs located on the International Space Station (ISS). All the PMAs on the ISS are identical but used slightly differently, and all three perform the same basic function of connecting a Common Berthing Mechanism port of an ISS module to an APAS-95 docking port of another module or visiting spacecraft.

The PMA is a truncated conical shell with a 24-inch axial offset in the diameters between the end rings. It is a ring-stiffened shell structure machined from 2219 aluminum alloy roll ring forgings welded together. PMA mechanical interfaces include a passive common berthing mechanism (PCBM) and a Russian Androgynous Peripheral Attach System (APAS).

Pressurized Mating Adapter (PMA): Converts an active Common Berthing Mechanism to APAS-95. Three PMAs are attached to the ISS, PMA-1 and PMA-2 were launched in 1998 on STS-88, PMA-3 in late 2000 on STS-92. PMA-1 is used to connect the Zarya control module with Unity node 1, Space Shuttles used PMA-2 and PMA-3 for docking.

The ISS Program has initiated plans to reconfigure modules to support establishment of two cargo vehicle berthing ports and two crew vehicle docking ports. As a result, the program will relocate the Permananent Multi-Purpose Module (PMM) and Pressurized Mating Adapter #3 (PMA-3). See Figure 1. This will result in cargo vehicle berthing ports on the

2018年1月10日 · The NASA document Space Station Program Androgynous Peripheral Assembly System to Pressurized Mating Adapter Interface Control Document, Part 1 Core (APAS to PMA-2 & 3 (SSP 42120) has a good diagram on page 3-14:

2025年2月1日 · Now, the ISS can be considered to be made of two segments (see image on right margin)- a Russian and an American one- that are connected to each other by an adapter, called the Pressurized Mating Adapter (PMA). There are actually three PMAs and PMA-1 is the one that connects the two segments (again, see image on right margin).

All the PMAs on the ISS are identical but used slightly differently, and all three perform the same basic function of connecting a common berthing mechanism (CBM) port of an ISS module to the Androgynous Peripheral Attach System (APAS) docking port of …

2021年11月1日 · PMA-1 links the U.S. and Russian segments of the ISS. The other two served as docking ports for the space shuttle and may be employed by commercial vehicles and the Orion Multi-Purpose Crew Vehicle (MPCV).
