6 Frequently Asked Questions about “Solar thermal power generation rotary joint”
How does the International Space Station use solar alpha rotary joints (SARJs)?
The International Space Station (ISS) utilizes two large rotating mechanisms, the solar alpha rotary joints (SARJs), as part of the solar arrays' alignment system for more efficient power generation.
What are solar array alpha rotary joints (SARJs)?
Specially designed bearings and drive mechanisms, aptly named “solar array alpha rotary joints,” or SARJs, are built into the ISS backbone truss adjacent to each PV wing to allow the panels to track the sunlight while the rest of the Station remains facing the surface of the Earth as seen in Figure 2.
What is a thermal radiator rotary joint (trrj)?
It's late here, more tomorrow. The "tilt angle" of the beam that the radiators are mounted on is called "gamma" in ISS parlance. The device is called the Thermal Radiator Rotary Joint (TRRJ) and the part of the device that passes the fluid connections across to the moving part is called the Flex Hose Rotary Coupler (FHRC).
What is a SARJ trundle bearing?
Public Use Permitted. The ISS utilizes two large rotating mechanisms, the SARJ, as part of the solar arrays alignment system for more efficient power generation. The SARJ is a 10.3m circumference, nitrided 15-5PH steel race ring of triangular cross-section, with 12 sets of trundle bearing assemblies transferring load across the rolling joint.
How often does SARJ rotate?
The SARJ mechanism rotates continuously and slowly – once every orbit, or every 90 minutes. In 2007, the starboard SARJ suffered a lubrication failure, resulting in severe damage (spalling) to one of the race ring surfaces.
Does a SARJ mechanism exist?
Such a document, however, does not seem to have existed. An early design paper written by NASA researchers best describes the SARJ mechanism (Ref. 3). This paper, which was not widely disseminated, outlined differing conceptual design approaches to building large rotary joints.
