A working mockup of the cabin window shade is on display in the PPG Aerospace booth 4251. The aviation trade show is being held at the Georgia World Congress Center here through Sept. 27.
According to Mark Cancilla, PPG global manager for commercial transparencies, the window shades enhance passenger comfort in the cabin and afford operating efficiencies to airlines.
“The electrochromic window shades replace the traditional pull-down plastic opaque shades in passenger cabin windows,” Cancilla said. “The PPG-Gentex system allows passengers to control the amount of light transmitted through the window. They can block out almost all of the light, let in abundant light with the shade in a bright, clear state, or ‘tune’ the amount of light or shade they want.”
For airlines, electrochromic window shades afford operating efficiencies, reduced maintenance and an attractive cabin, Cancilla said.
The electrochromic system defaults to a clear state on power loss and has a fast darkening speed, he added.
PPG and Gentex formed a relationship specifically to commercialize the window shade systems. PPG is overseeing testing and qualification, performing final assembly and marketing the systems, and will manage aftermarket support for its customers. Gentex is providing its patented dye-based electrochromic technology and manufacturing the electrochromic panels.
PPG has a contract to supply the electronically dimmable window systems for the Boeing 787, which will be their first commercial application.
Electrochromic technology uses electricity to darken or change the color of an electrically conductive medium between two thin glass plies. Turning off the electricity lightens or bleaches the medium.
