Chemistry in plumes of high-flying aircraft with H2 combustion engines: a modelling study [PDF]
Recent discussions on high-speed civil transport (HSCT) systems have renewed the interest in the chemistry of supersonic-aircraft plumes. The engines of these aircraft emit large concentrations of radicals like O, H, OH, and NO.
