        Design Innovation for Jet-Powered Flight: The Swept Wing

        Discover the origins of the swept wing and podded engine design, two technologies that helped engineers harness the speed potential of jet engines, in this video from WGBH and The Documentary Group. Today, most jetliners share a common design: wings that sweep back from the body of the plane, with engines mounted beneath them. This design dates back to the end of World War II, when Allied military forces discovered secret German research that had been meant to be destroyed. Swept wings delay the formation of shock waves at higher speeds, and podded engines suspended below the wings help bring wing vibration under control. Together, these technologies enabled stable flight at speeds twice as fast as those that propeller engines had previously generated. This resource is part of the Aerospace Engineering Collection.
