COMBINED METHOD FOR RESTORATION OF ATMOSPHERIC OZONE LAYER Russian patent published in 1997 - IPC

FIELD: environment control. SUBSTANCE: method involves conveying ozone to predetermined altitude by means of aircraft having hydrogen container, liquid oxygen container provided with adjustable electric heater to gasify oxygen. high-voltage transformer and ozone generator. Stoichiometric hydrogen+oxygen mixture may serve as fuel for aircraft engine and water as combustion product in the form of hot vapors is separated under the action of solar radiation at the altitude of 20-25 km into volatile hydrogen and oxygen, whose molecules dissociate to produce ozone. At 20-25 km altitude, gaseous oxygen is delivered into ozone generator, where ozone and atomic oxygen are produced with following discharge through pipeline into atmosphere. EFFECT: increased efficiency in maintaining atmospheric ozone layer and enhanced reliability in operation.
