Narrative:

We began the takeoff roll [and] after captain called 'set takeoff thrust'; I made a small adjustment and called 'thrust set'. There was a sort of thud sound as I called '80 knots'. The captain rejected the takeoff almost immediately after the callout; and the smell of something burning filled the aircraft. I told ATC that we were rejecting and we came to a stop on the runway. Querying the tower; he said he saw no smoke. The engine indications were normal at idle. We pulled off and asked him to roll the trucks to see if we might have anything else that warranted immediate attention. Afterward we taxied to the gate and performed an inspection of the left engine. At least three blades of the fan were damaged. We contacted maintenance and eventually swapped aircraft.
