Abstract
A gas turbine engine has a combustor section using an axial prediffuser with an off-axis cowl passage formed by a diffuser outer wall and a combustor outer cowl. Flow from the prediffuser is split into intermediate outer and inner shroud passages and then the intermediate outer passage is further split into a outer shroud passage and a combustor cowl passage which supplies air to the fuel nozzles. The outer passage and cowl flow split is delayed to improved pressure supply and flow distribution to the outer passage.
