When a jet is flying faster than the speed of sound, one small mistake can tear it apart. And when the jet is so experimental that it must fly unmanned, only a computer control system can pilot it. Ohio State University engineers have designed control system software that can do just that -- by adapting to changing conditions during a flight. Government agencies have been developing faster-than-sound vehicles for decades. The latest supersonic combustion ramjets -- called scramjets -- burn...
