An unmanned hypersonic glider likely aborted its 13,000 mph flight over the Pacific Ocean last summer because unexpectedly large sections of its skin peeled off, the U.S. Defense Advanced Research Projects Agency said Friday.
An unmanned hypersonic glider developed for U.S. defense research into super-fast global strike capability was launched atop a rocket early Thursday but contact was lost after the experimental craft began flying on its own, the Defense Advanced Research Projects Agency said.
"The result of these findings is a profound advancement in understanding the areas we need to focus on to advance aerothermal structures for future hypersonic vehicles. Only actual flight data could have revealed this to us," he said.
"We know how to boost the aircraft to near space," he said. "We know how to insert the aircraft into atmospheric hypersonic flight. We do not yet know how to achieve the desired control during the aerodynamic phase of flight. It's vexing; I'm confident there is a solution. We have to find it."
