Combustion chamber with optimised dilution and turbomachine equipped with same

摘要

The chamber has dilution holes (30b) formed in two rows (34b, 35b), where the holes of the row (34b) are situated at same distance along an axis of the chamber with respect to elementary holes (20b) of an annular outer wall (7b). The holes (20b) are formed at an angular position same as that of a part of the holes (30b) of the row (35b). Positions of the holes (30b) formed between the two consecutive holes (20b) form a repeated pattern on any circumference of the wall. Distances between the holes (20b, 30b) are larger than or equal to two times of large diameter of the holes (30b).
