  1. NASA Sigma Series — Breaking the Sound Barrier

    October 4, 2022, 7:30 PM - 8:30 PM

    Streaming online through NASA Langley

    Peter Coen, mission integration manager for NASA’s Quesst Mission, will discuss supersonic flight. Seventy-five years ago, Charles “Chuck” Yeager and the Bell X-1 aircraft “broke” the fictitious sound barrier by flying faster than the speed of sound. The rapid development of supersonic aircraft uncovered a real barrier to commercial supersonic flight: the unacceptably annoying sonic booms. That sound led to restrictions on supersonic flight over land and relegated the Concorde to technological success, but only flying supersonic over water. After decades of research leadership, NASA has developed technology that reduces the sonic boom to a soft “thump.” Now NASA’s Quesst Mission is poised to demonstrate this technology with the X-59: a purpose built supersonic experimental aircraft.
