1. A flow conditioning device for a can annular gas turbine engine, comprising: a plurality of flow directing elements disposed in a compressed air flow path lead-ing to a combustor; andthe plurality of flow directing elements configured for relative adjustment of at least one flow directing element
1. A flow conditioning device for a can annular gas turbine engine, comprising: a plurality of flow directing elements disposed in a compressed air flow path lead-ing to a combustor; andthe plurality of flow directing elements configured for relative adjustment of at least one flow directing element with respect to an adjacent flow directing element during operation of a gas turbine engine effective to adjust a level of choking of the compressed air flow path; andwherein the plurality of flow directing elements further comprise a plurality of annular plates, wherein each of the plurality of annular plates has a top surface, a bottom surface and a perimeter, wherein each of the plurality of annular plates comprises at least one opening through the top surface and bottom surface, wherein the openings are associated with each other to establish at least one flow conditioning path through the plurality of annular plates, and wherein rotation of one annular plate with respect to another adjusts a size of the at least one flow conditioning path. 2. The flow conditioning device of claim 1, configured such that adjustment of the at least one flow directing element during operation of the gas turbine engine is effective to increase the level of choking of the compressed air flow path without increasing a level of swirl in a compressed air flow through the compressed air flow path. 3. The flow conditioning device of claim 1, wherein the plurality of annular plates are disposed adjacent one another and radially outward of a combustion assembly comprising the com-bustor and a transition duct. 4. The flow conditioning device of claim 1, wherein the plurality of annular plates are disposed proximate a combustor inlet head end. 5. The flow conditioning device of claim 1, comprising a fuel injector associated with at least one of the flow directing elements. 6. A flow conditioning device for a can annular gas turbine engine, comprising: a plurality of annular plates disposed in a compressed air flow path leading to a combustor and adjacent one another along a direction of flow, wherein each of the plurality of annular plates has a top surface, a bottom surface and a perimeter, wherein each of the plurality of annular plates comprises at least one opening through the top surface and bottom surface; wherein the at least one opening of each of the plurality of annular plates are associated with each other to establish at least one flow conditioning path through the plurality of annular plates; andwherein rotation about a common axis of one plate with respect to another adjusts a hydraulic diameter of the least one flow conditioning path during operation of the can annular gas turbine engine. 7. The flow conditioning device of claim 6, wherein a surface of at least one plate defines at least part of a fuel path, and the fuel path leads to a fuel injector associated with the at least one flow conditioning path. 8. A flow conditioning device for a can annular gas turbine engine, comprising: a plurality of flow directing elements disposed in a compressed air flow path lead-ing to a combustor; andthe plurality of flow directing elements configured for relative adjustment of at least one flow directing element with respect to an adjacent flow directing element during operation of a gas turbine engine effective to adjust a level of choking of the compressed air flow path; andwherein the flow directing elements further comprise a plurality of annular plates having the same shape, wherein each of the plurality of annular plates comprises at least one opening, wherein the openings are associated with each other to establish at least one flow conditioning path through the plurality of annular plates, and wherein rotation of one annular plate with respect to another adjusts a size of the least one flow conditioning path.
