How The Boeing 787 Dreamliner’s Dimmable Windows Work

A unique feature of the Boeing 787 Dreamliner is its dimmable windows, which enhance passenger comfort and overall experience. The Dreamliner’s windows employ an electrochromic technology, as opposed to conventional aircraft windows with physical shades.

Electrochromic windows are made of special materials that can change their tint or opacity when an electric voltage is applied. In the case of the boeing 787 dreamliner, There are two pieces of glass with a thin layer of gel between them. The gel’s opacity is altered chemically when an electrical current is applied to it.

The passengers cannot see the electrodes because they are positioned on the sides of the windows. Additionally, the windows are networked so that flight attendants can have centralized control.

A button or touchscreen control next to each passenger’s seat allows them to change the amount of tint in the windows. Passengers can control the amount of sunlight entering the cabin without using physical window shades with technology that allows a gradual transition from transparent to different shades of dimness.

These dimmable windows have numerous advantages. The crew can create a cosier atmosphere inside the cabin and passengers can enjoy the outside view without glare. In addition to reducing the need for conventional window treatments, the dynamic control over light also contributes to a sleek and contemporary interior design.

Furthermore adding to the dreamliners overall energy efficiency are the dimmable windows. The aircraft can better control its temperature and save fuel by minimizing the amount of direct sunlight and the need for physical shade.

Overall, the Boeing 787 dreamliner dimmable windows demonstrate state-of-the-art technology that improves passengers’ in-flight experiences while providing useful benefits in terms of energy efficiency and aesthetic design.

Boeing has achieved a significant milestone by providing NASA with the second core stage of the Space Launch System (SLS) rocket.

This crucial component, crafted at NASA’s Michoud Assembly Facility (MAF), is set to propel the Artemis II crew into lunar orbit, marking humanity’s return to deep space after a 50-year hiatus.

The monumental Boeing-built rocket stage, the largest element of the Artemis II mission, will embark on a journey aboard the Pegasus barge, traveling 900 miles to NASA’s Kennedy Space Center.

Upon arrival, it will be meticulously integrated with other essential Artemis II components, including the upper stage, solid rocket boosters, and NASA’s Orion spacecraft within the iconic Vehicle Assembly Building. This intricate integration process is a vital step toward the eagerly anticipated Artemis II launch, slated for 2025.

“Boeing-built products helped land humankind on the moon in 1969, and we’re proud to continue that legacy through the Artemis generation,” remarked Dave Dutcher, vice president and program manager for Boeing’s SLS program. “Together, with NASA and our industry partners and suppliers, we are building the world’s most capable rocket and paving the way to deep space through America’s rocket factory in New Orleans.”

The delivery of Core Stage 2 marks a significant achievement in the evolution of the SLS rocket. Towering over 200 feet and powered by four RS-25 engines, this core stage, coupled with two solid-fueled booster rockets, will generate a staggering 8.8 million pounds of thrust. This immense power is crucial to launching Artemis II and future missions into the vast expanse of space.

The SLS rocket stands unparalleled in its capability to transport both crew and substantial cargo to the moon and beyond in a single launch. Its extraordinary capacity will facilitate the delivery of human-rated spacecraft, habitats, and scientific missions to destinations including the moon and Mars, ushering in a new era of space exploration.
