GAS TURBINE ENGINE ROTARY INJECTION SYSTEM AND METHOD

摘要

A rotary injector (95, 222) comprising one or more radially-extending arms (93) provides for injecting fuel (12, 12.1, 12.4) into a combustion chamber (16). The combustion chamber (16) receives air (14) from locations upstream and downstream of the rotary injector (95, 222), and the arms (93) of the rotary injector (95, 222) are adapted so that a pressure (P2) in the combustion chamber (16) upstream of the rotary injector (95, 222) is less than a pressure (Po") in a plenum (212) supplying air (14) to the combustion chamber (16) upstream of the rotary injector (95, 222).
