1. A tangential on-board injector (TOBI) for a gas turbine engine, the TOBI comprising: at least one adjustable strut configured to control an airflow through the TOBI, the at least one adjustable strut moveable to change an airflow characteristic within the TOBI,wherein the at least one adjustable strut is operably connected to a vane of the gas turbine engine, wherein operation of the operably connected vane causes adjustment of the at least one adjustable strut. 2. The tangential on-board injector of claim 1, wherein the at least one adjustable strut comprises a body and at least one pivot, wherein the body is configured to rotate about the at least one pivot. 3. The tangential on-board injector of claim 1, wherein the at least one adjustable strut comprises a body defining a fixed portion and at least one flap portion, wherein the at least one flap portion is moveable relative to the body. 4. The tangential on-board injector of claim 3, wherein the at least one flap portion is moveable on a hinge. 5. The tangential on-board injector of claim 3, wherein the body has a suction side and a pressure side, wherein the at least one flap portion is located on the pressure side of the body. 6. The tangential on-board injector of claim 3, wherein the body has a suction side and a pressure side, wherein the at least one flap portion is located on the suction side of the body. 7. The tangential on-board injector of claim 3, wherein the at least one flap portion comprising at least two flap portions. 8. The tangential on-board injector of claim 7, wherein the at least two flap portions are configured to move independently of each other. 9. A gas turbine engine comprising: a tangential on-board injector (TOBI) having: a plurality of adjustable struts configured to control an airflow through the TOBI, each adjustable strut moveable to change an airflow characteristic within the TOBI, anda plurality of stationary struts,wherein the plurality of adjustable struts are configured to alternate within the TOBI with the plurality of stationary struts. 10. The gas turbine engine of claim 9, wherein the at least one adjustable strut comprises a body and at least one pivot, wherein the body is configured to rotate about the at least one pivot. 11. The gas turbine engine of claim 9, wherein the at least one adjustable strut comprises a body defining a fixed portion and at least one flap portion, wherein the at least one flap portion is moveable relative to the body. 12. The gas turbine engine of claim 11, wherein the at least one flap portion is moveable on a hinge. 13. The gas turbine engine of claim 11, wherein the body has a suction side and a pressure side, wherein the at least one flap portion is located on the pressure side of the body. 14. The gas turbine engine of claim 11, wherein the body has a suction side and a pressure side, wherein the at least one flap portion is located on the suction side of the body. 15. The gas turbine engine of claim 11, wherein the at least one flap portion comprising at least two flap portions. 16. The gas turbine engine of claim 15, wherein the at least two flap portions are configured to move independently of each other. 17. The gas turbine engine of claim 9, wherein the at least one adjustable strut is operably connected to a vane of the gas turbine engine, wherein operation of the operably connected vane causes adjustment of the at least one adjustable strut. 18. A method of manufacturing a gas turbine engine having a tangential on-board injector (TOBI) the method comprising: operably connecting at least one adjustable strut to a vane of the gas turbine engine, the at least one adjustable strut configured to control an airflow through the TOBI, the at least one adjustable strut moveable to change an airflow volume within the TOBI,wherein operation of the operably connected vane causes adjustment of the at least one adjustable strut.
