The NASA High Speed Research Program conducted an extensive evaluation of the effects of emissions from a supersonic high speed civil transport (HSCT) on the stratospheric ozone layer. That study evaluated the effect of fleet size, cruise altitude, NOx emission levels, water vapor emissions and sulfate emissions on ozone. Supersonic business jets (SSBJs) would be much smaller and would burn much less fuel than the HSCT. In addition, the SSBJ concepts that have been discussed are for aircraft that would fly slower than Mach 2.4 and at lower altitudes. The daily utilization of private supersonic business jets is expected to be smaller than for scheduled airliners. So, the SSBJ fleet fuel use at cruise altitudes is expected to be much lower than for the HSCT scenarios used previously. Because of the limited market for such aircraft, SSBJs might use conventional combustors with higher NOx emissions levels than the advanced technology combustors that were being developed as part of the HSR program. In this report, a two-dimensional model is used to evaluate parametrically the ozone impact of supersonic business jets as a function of fleet fuel use at cruise altitudes, NOx emission index (grams of NOx/kilogram of fuel used), and cruise altitude.
