Ozone Concentration in the Cabin of a Gates Learjet Measured Simultaneously With Atmospheric Ozone Concentrations

摘要

A Gates Learjet Model 23 was instrumented with monitors to measure simultaneously the atmo¬spheric and the cabin concentrations of ozone at altitudes up to 13 kilometers. Six data flights were made in February 1978. Results indicate that a only a small amount of the atmospheric ozone is destroyed in the cabin pressurization system. Ozone concentrations measured in the cabin near the conditioned-air outlets were only slightly lower than the atmospheric ozone con¬centration. For the two cabin configurations tested, the ozone retention in the cabin was 63 and 41 percent of the atmospheric ozone concentration. Maximum cabin ozone concentration mea¬sured during these flights was 410 parts per billion by volume.
