  "textContent": "A combined air turbine starter and flow control valve includes a turbine (28) having turbine blades (44) and a shaft rotating with the turbine blades (44). The turbine (28) is received within a nozzle housing. The nozzle housing includes an inlet. A radially outwardly extending inner surface extends from the inlet and toward the turbine blades. A flow control piston is received to be movable along a rotational axis of the turbine shaft, and toward and away the radially outwardly extending surface of the nozzle housing. A control (48) is programmed to direct a movement system to position the flow control piston relative to the radially outwardly extending surface to achieve a desired volume of airflow to the turbine blades. A gas turbine engine starting system is also disclosed.",
