Combustion chamber for gas turbine engine has first and second turbulators for staged mixing of charge to combustion chamber

摘要

The combustion chamber with staged premixing (120) mixes a forced air feed (150) from a compressor (110) and a fuel feed (170) from a supply (160). The intake has a first turbulator (180) for mixing the air and fuel feeds in a first charge flow (190). There is a second flow source (200) to produce a flow downstream of the first turbulator. There is a second turbulator (220) for mixing the first fuel-air flow and the second flow. Claims include a method of mixing the flows.
