ABSTRACT:
A device to produce vehicle braking from a two-shaft gas turbine engine including an air brake with a centrifugal impeller on the power turbine shaft, the impeller having blades forwardly turned at the impeller exit through an angle greater than sixty degrees for absorbing energy from the power turbine shaft thereby to control power transfer to an output shaft. The system includes a variable inlet control assembly to throttle inlet air flow to the air brake impeller so as to regulate the amount of power absorption from the power turbine shaft.
