US Patent 11021259 Aircraft exhaust mitigation system and process

A system for neutralizing exhaust gases from an aircraft at altitude includes a turbofan jet engine. The turbofan jet engine creates exhaust gases. An exhaust is located within the turbofan jet engine. The exhaust has an interior volume. At least one corona discharge unit is located within the interior volume of the exhaust. The at least one corona discharge unit creates electrical discharges comprising high-speed relativistic electrons and gamma rays within the exhaust. The exhaust gases and the electrical discharges are directed to interact with one another in the interior volume of the exhaust. The interaction generates positively charged plasma ions within the exhaust gases. The exhaust gases are neutralized before leaving the turbofan jet engine.
