International Classification:

F02C 1/00
F02G 3/00

US Classification:

60737, 60740, 2395332

Abstract:

A premixing injector for use in gas turbine engines assists in the lean premixed injection of a gaseous fuel/air mixture into the combustor of a gas turbine. The premixing injector is designed to mix fuel and air at high velocities to eliminate the occurrence of flashback of the combustion flame from the reaction zone into the premixing injector. The premixing injector includes choked gas ports, which allow the fuel supply to be decoupled from any type of combustion instability which may arise in the combustor of the gas turbine and internal passages to provide regenerative cooling to the device.

Abstract:

A compact and lightweight hybrid vehicle power source employs an integrated engine hybrid electric boost power design that operates on a single battery bank for all electrical functions. An integrated flywheel, cooling fan and a single hybrid electric motor drive, engine starter, electromagnetic regenerative braking device and battery charging alternator are combined. The flywheel alternator/starter/hybrid-drive configuration generates electrical power for battery recharging and parasitic loads, rotates the engine for starting, provides boost power for faster vehicle accelerations, provides regenerative braking for faster decelerations, provides inertia for smooth engine operation, and provides pressurized air for forced convection cooling.
