Bombardier Learjet 85 Aircraft Window Contract Awarded to PPG Aerospace

PPG Industries' aerospace transparencies group has been awarded a contract by Bombardier Learjet to design and manufacture heated glass windshields and side cockpit windows for the Learjet 85 aircraft. PPG will supply original-equipment flight-deck windows and aftermarket parts to Bombardier Learjet for operators of the Learjet 85 business jet, according to Arthur Scott, PPG Aerospace global director for general aviation transparencies.

"Bombardier Learjet wanted glass windshields and cockpit windows for the Learjet 85 aircraft, and PPG was selected because of our expertise and history designing and producing sophisticated glass transparencies," Scott said. "They will use our latest sealant and interlayer technology for extended service life."

The four windows will wrap around the cockpit to enhance visibility and aerodynamics, with the large windshields formed into complex, compound shapes, according to Scott. Three plies of Herculite II chemically strengthened glass will afford strong, lightweight transparencies. The windshields will be designed to resist impact by a 4-pound bird at 300 knots.
