The company ships them with these giant trucks. GE Aviation also assembles jet engines in Peebles. Peebles also has outdoor test stands where engineers can simulate everything from hail storms to bird strikes. The test cells and their massive air inlets from the outside. The blade design was so striking that New York's Museum of Modern Art included one blade in its collection.Ī close-up of the composite blades and their titanium edge. Composites allow engineers to build larger and more efficient jet engines. GE is the company whose jet engines have fan blades made from composite materials. This air generates most of the engine's thrust. These blades are controlling airflow around the core of the jet engine. When that happens, it distorts the data.”Īn inside view of a GEnx jet engine. Image of the Day Image of the Day Atmosphere Heat Human Land Life Natural Event Remote Sensing Snow & Ice Water Reservoirs Rise, but Groundwater Woes Remain The water delivered by winter storms in 2022-2023 is likely insufficient to reverse the longer-term depletion of California’s groundwater. “A large engine like the GE90 will pull a little tornado from the walls if the airflow doesn’t cut it off. “When the engine runs and it’s not moving, it’s kind of like a giant vacuum cleaner,” says "cell owner" Ray Staresina. Engines like the GE90-115B, the world's largest and most powerful jet engine, can swallow as much as 8,000 pounds of air per second. Many Boeing 787 Dreamliners use the slightly larger GEnx-1B.Īn engineer stands by an air inlet into a test cell. This engine powers Boeing's 747-8 aircraft. The construction team vibrated the wet concrete down to squeeze out air and eliminate weak spots.Ī GEnx-2B jet engine inside a test cell. Jet engine test cells have 20-foot-thick walls built from a special high-density concrete. This GEnx jet engine could be easily mistaken for a machine designed by H.R. Up close, the sphere appears translucent.įrom Star Wars to Alien. Above: The Death Star-like turbulence control structure (TCS) streamlines the air flowing inside a jet engine during testing. Top image: A cowl for a GEnx engine stretches out like a giant mechanical moth. “You’ve got to prove that your engines are good.” We recently sent photographer Chris New to check Peebles out. Topics: mars exploration rover mer, jpl, jet. In this view from behind a test rover at NASA Jet Propulsion Laboratory, Pasadena, Calif., the rear wheels of the rover are turned toward the left, and the left-front wheel is turned toward the the right. Free for commercial use, no attribution required. “Some of these tests are relatively benign, but others are quite damaging,” DeBruin told GE Reports. Download Image of Preparing for Rover Pivot Test. He and his team even set off small explosions inside jet engines to simulate blade failure. DeBruin runs GE Aviation’s jet engine test operations site in Peebles, Ohio, and his job is to make sure that GE engines keep working when they fly into an hailstorm, encounter a dust cloud or ingest a goose. Every day is a bad day for flying if you hang out with Brian DeBruin.
