Second Hypersonic Flight Brings New Flight Test Data

first_img A second test of the X-51A Waverider flew in the Point Mugu Naval Air Test Range over the Pacific Ocean, bringing significant hypersonic research data. The hypersonic aircraft was successfully boosted to just over Mach 5 and the scramjet engine lit, but failed to transition to full power. Air Force Flight Test Center officials said after a flawless flight from Edwards Air Force Base a U.S. Air Force B-52H Stratofortress released the experimental vehicle from an altitude of approximately 50,000 feet. After release the X-51A was initially accelerated by a solid rocket booster to a speed just over Mach 5. According to Charlie Brink, the Air Force Research Laboratory’s X-51A program manager, U.S engineers are reviewing the large amount of telemetry data collected during the test flight to identify the cause of the anomaly. “Obviously we’re disappointed and expected better results,” said Brink, “but we are very pleased with the data collected on this flight.” “I am extremely pleased with the AFFTC and Point Mugu’s support and execution of this complex flight test mission as they provided us every opportunity for success in this endeavor,” said Brink. “We have attempted two scramjet experiments now where one successfully lit, and one did not.” “We will continue to examine the data to learn even more about this new technology,” he said. “Every time we test this new and exciting technology we get that much closer to success.” Boeing and Pratt & Whitney Rocketdyne built four X-51A flight test vehicles with the program goal of reaching Mach 6 in hypersonic flight. The next flight is tentatively schedule for fall 2011. By Dialogo July 08, 2011last_img
