ISS Astronauts Install Two Advanced Solar Arrays Provided by Boeing

New Solar Arrays to Power NASA’s International Space - As the International Space Station orbits Earth, its four pairs of solar arrays soak up the sun’s energy to provide electrical power for the numerous research and science investigations conducted every day, as well as the continued operations of the orbiting platform. Boeing have increased the International Space Station (ISS) power supply by providing two new, advanced solar arrays. European astronaut Thomas Pesquet and NASA astronaut Shane Kimbrough installed them during three spacewalks on June 16, 20 and 25. The new arrays contain stronger solar cells that are also more efficient than their predecessors. Measuring 61 feet long and 20 feet wide, they generate twice the power in half the space of the original arrays that they partially cover. Boeing provided the new arrays to NASA, with solar cells from Spectrolab and a structure from Redwire that allowed the arrays to be rolled tight for launch and unroll with their own energy i

Halon Replacement in Aviation Industry

ICAO has mandated the use of Halon replacements in fire extinguishers used on civil transport aircraft. The Halon replacement cut off dates in ICAO SARPs contained in Annex 6 and 8: Lavatory fire extinguishing systems - 31 Dec 2011 Portable fire extinguishers - 31 Dec 2018 Engine and APU fire extinguishing systems - 31 Dec 2014 Cargo compartment fire extinguishing systems - 28 Nov 2024 Halon still remains one of the most effective fire extinguishing agents available. However, there is no new production. Halon is considered a clean agent by The National Fire Protection Association because it’s electrically non-conducting and does not leave a residue. Halon has an extremely high potential to deplete the ozone layer and contribute to global warming. On January 1, 1994, Halon production ceased in compliance with the Montreal Protocol and the U.S. Environmental Protection Agency. The ozone layer is a region of the upper atmosphere containing relatively high concentrations of ozone (O3) mo

EASA proposes use of new technology to support all-weather operations

The European Union Aviation Safety Agency published a proposal to update the regulatory framework applicable to all-weather operations (AWOs) and flight crew training to allow the application of latest technological advancements. This proposal would increase the number of medium-sized aerodromes which are accessible for flight operations. The concept of all-weather operations refers to the ability of aircraft to take off and land in an airport under low visibility conditions. In such circumstances, technological support can ensure safe operations in situations that would otherwise pose safety challenges. While large aerodromes are, for the most part, already equipped for such operations, medium-size or regional airports had typically so far been unable to afford the investment required. “This Opinion is innovative in certifying the use of technologies that are already available to increase safety, while at the same time broadening the commercial network by increasing the accessibility
