Aerion has started its next round of high-speed test flights, in conjunction with NASA Dryden Flight Research Center, to validate the laminar-flow wing for its supersonic business jet. These tests, using a test article mounted under the centerline of NASA’s F-15B research aircraft and flown at speeds up to Mach 2.0, are intended to measure the real-world robustness of supersonic natural laminar flow. Information from these tests will help define manufacturing standards for surface quality and assembly tolerances of the proposed SSBJ’s laminar-flow wing.
