Fan would not exit like a prop at all. At the rotational sppeds they do the fan would be absolutely rigid (like a toque converter,) As soon as it encountered something fixed it would start chewing it but it would also 'rotate around that point' then it would most likely roll around the inside of the containment (or cowl) until it chewed or forced its way out. By then it might have generated quite a lot of transverse energy and would depart perhaps forward but also in the random direction where it finally got free. Unless it hit something really rigid gyro effect would keep it 'upright.' 20% chance it chews into something important like the fuselage or No 2?
