A flyback transformer always includes a gap in its core. It is 
designed to store energy in the core on one half cycle and release it 
to its various windings  on the other. You can view a flyback 
transformer as separate chokes sharing a common core. HOwever, 
the chokes are bound to each other by their turns ratios when it 
comes to calculating voltages across the various windings,
       A normal transformer ideally stores no energy in its core but in 
practice always stores some due to the magnetizing current.
