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 preselec...


A combustor assembly comprising a liner having an inlet and an outlet, a dome overlying the inlet and including means forming a passage for flow of primary combustion air into the liner, a fuel nozzle for directing fuel spray into a reaction mixing zone downstream of said dome, a plurality of slots with major and minor axes formed in said liner downstream of said dome, each of said slots having its major axis formed at an angle to the longitudinal axis of said liner, a control band rotatably supported on said liner in overlying relationship to said slots...
