HYBRID JET-TURBINE AIRCRAFT ENGINE Russian patent published in 2014 - IPC F02K3/00 

FIELD: engines and pumps.

SUBSTANCE: hybrid jet-turbine aircraft engine contains a combustion chamber and fuel elements based electrochemical generator located out of the chamber, connected by inlet to hydrocarbon fuel source and air flow compressed in engine, and a controller. The combustion chamber outlet is connected to low pressure turbine via high pressure turbine. The electrochemical generator outlet is connected to electric motor installed on low pressure turbine shaft. The controller is connected to controls, located in path of fuel and air flow, and is designed with possibility of relation adjustment of air flow and fuel flow coming to electrochemical generator and combustion chamber, and possibility of mixture of various energies of electric generator and low pressure turbine in the form of electric energy and thermal energy of combustion products for drive shaft.

EFFECT: reducing toxics emission during flight cycle, noise reduction including airports zones, improving efficiency.
