  Inputs:
    name:           J69-T25
    type:           turbine
    thrust:         1025 lb
    augmented?      no
    injected?       no

  Note:
    Bypass ratio is only used by the turbine model to estimate the
    rotational inertia of the engine.  In this case, even though the
    engine is a turbojet, a bypass ratio is used to simulate the high
    rotational inertia of the centrifugal compressor.
