Abstract : The report discusses the possibility that nitric oxide (NO) in the exhaust of a fleet of SSTs could seriously affect the ozone equilibrium of the stratosphere. In this connection it has been suggested that artificial excitation (vibrational or electronic) of NO in the combustion chamber could increase its reaction rate so that NO is converted into the more inert N2. The maximum rate that could likely be thus obtained seems inadequate to deplete the NO abundance appreciably. However, there are still uncertainties in the parameters and the mechanism cannot be totally discounted. (Author)
