NASA Quiet Short-Haul Research Aircraft (QSRA) Carrier Trials

The Quiet Short-Haul Research Aircraft (QSRA) is a flight research facility for investigating STOL operations. The aircraft is a highly modified De Havilland C-8A Buffalo consisting of a new swept, supercritical wing and 4 YF-102 geared, high-bypass-ratio turbofan engines mounted in an “over-the-wing“ installation. Upper surface blowing is used to generate high-lift coefficients to provide low approach speeds and steep approach path angles.
