Abstract: A blisk fan is provided for a turbine engine propulsion system. The blisk fan includes a hub configured to rotate about a rotational axis at a maximum rotational speed, and a plurality of blades extending radially outward from the hub to define a fan leading edge tip diameter. Each of the blades has a first vibratory mode at a natural frequency, which is greater than a first fan order and less than a second fan order at the maximum rotational speed. The compression system preferably has a balance factor of the compression system between 1.9 and 3.2.

Abstract: An air turbine starter (ATS) includes a support structure and a turbine. The ATS additionally includes a gear train that is configured for receiving torque input from the turbine. The gears include an integrated input gear. The ATS further includes an output member. The output member is operably coupled to the gear train and a main engine input member. The output member is configured to transfer torque from the gear train to the main engine input member. Additionally, the ATS includes a motor system that is supported by the support structure. The motor system includes a motor and a motor output gear. The motor output gear is configured to engage the integrated input gear for selectively delivering motor torque from the motor to the integrated input gear such that the motor torque transfers to the main engine input member to selectively dry motor the main engine at a predetermined speed.
