ABSTRACT:
A variable flow air controller for a gas turbine engine combustor has a rotatable band including a first plurality of slots formed therein that overlie a plurality of primary air admission slots in the combustor wall circumferentially therearound and directed radially into a primary combustion zone. The slots are arranged to form an open junction therebetween which shifts axially along the combustor assembly upon rotation of the band thereby to control the point of admission of primary air into a combustion apparatus for completing combustion at preselected positions downstream of a liner dome in accordance with engine operation.
