Benefit-Function Of Two- Identical Cold Standby Space Station System Subject To Failure Due To Damaged Starboard Solar Alpha Rotary Joint Or Failure Due To Excessive Vibration During Reboost
Abstract
Benefits of ISS Research, Earth framing the International Space Station in May 2010 following undocking of
Atlantis during the STS-132 mission. (NASA) Almost as soon as the International Space Station was habitable, researchers
began using it to study the impact of microgravity and other space effects on several aspects of our daily lives. This unique
scientific platform continues to enable researchers from all over the world to put their talents to work on innovative
experiments that could not be done anywhere else. Although each space station partner has distinct agency goals for station
research, each partner shares a unified goal to extend the resulting knowledge for the betterment of humanity. We may not
know yet what will be the most important discovery gained from the space station, but we already have some amazing
breakthroughs! In the areas of human health, telemedicine, education and observations of Earth from space, there are already
demonstrated benefits to human life. Vaccine development research, station-generated images that assist with disaster relief
and farming, and education programs that inspire future scientists, engineers and space explorers are just some examples of
research benefits. The stories featured here summarize the scientific, technological and educational accomplishments of
research on the space station that has and will continue to have an impact on life on Earth. The benefits outlined here serve
as examples of the space station's potential as a groundbreaking scientific research facility. Through advancing the state of
scientific knowledge of our planet, looking after our health, and providing a space platform that inspires and educates the
science and technology leaders of tomorrow, these benefits will drive the legacy of the space station as its research
strengthens economies and enhances the quality of life here on Earth for all people. In this paper we have taken failure due to
damaged starboard Solar Alpha Rotary Joint or failure due to Excessive vibration during reboost. When the main unit fails
due to failure due to damaged starboard Solar Alpha Rotary Joint then cold standby system becomes operative. Failure due
to collision cannot occur simultaneously in both the units and after failure the unit undergoes very costly repair facility
immediately in case of launch failure. Applying the regenerative point technique with renewal process theory the various
reliability parameters MTSF, Availability, Busy period, Benefit-Function analysis have been evaluated.
