90 МЕТРОВ: Как выпекают гигантское крыло в вакууме, чтобы оно не развалилось на 300 км/ч

A 90-METER WIND TURBINE BLADE: How a giant wing is baked in a vacuum so it doesn't fall apart at 300 km/h It's longer than a football field and larger than the wing of the largest passenger jet, yet weighs only 25 tons—less than a single train car. The tip of this giant flies at 300 kilometers per hour, and under such a load, a single air bubble inside or a millimeter of geometric error would cause the structure to instantly shatter into pieces. Today, we're visiting a closed mega-engineering factory to see how these composite monsters are created. You'll find yourself inside gigantic workshops, as clean as laboratories, and witness the entire process of hand-assembling and "baking" a wing. We'll show you the cyclopean 90-meter-long molds, heated from below to exactly 70 degrees Celsius, and the process of laying down 120 layers of ultra-fine fiberglass and carbon fiber, which withstand tensile loads greater than steel. We'll explore the technology of vacuum infusion under a pressure of one hundredth of an atmosphere, where liquid resin completely saturates the monolithic structure in six hours, the secrets of gluing the two halves of a blade, protection from raindrop impacts (which act like bullets at high speed), and the insane process of transporting a 90-meter-long rigid structure on public roads at night. 📍 Timestamps: 00:00 — Wind turbine blades: from layer laying to vacuum impregnation. 08:54 — Secrets of fiberglass production: how strong threads are produced from sand. 20:01 — Composite rebar: the process of creating a steel replacement. 30:24 — Industrial turbines: rotor forging and filigree blade precision. 41:52 — Giant propellers: cast from 140 tons of bronze and mirror-polished. 55:24 — Aircraft engines: single-crystal alloys and 3D printing in aviation.
