Narrative:

Transitioning east to west through class D airspace nfw tower. Contacted tower; [stated] our intentions to transition east to west; tower indicated to proceed as requested. I heard chatter between tower and other air traffic. I spotted what appeared to be a flight of two aircraft at my 2 o'clock and closing they appeared to be out a ways as I watched closer it looked as though we would cross close to each other. I reduced collective power and began a descent. The two F18 jets came across the front of the aircraft; one rolled up and the other aircraft stayed on course as I was going low. Tower never indicated to me of the two aircraft inbound on what would be the downwind leg to land at the airport. Tower called and said sorry was all and did not indicate to whom they made that call. My aircraft did not have TCAS or radar so I was only reliant on visual separation. When you recognize that an aircraft is at your level and closing; vertical separation is key because it is not easy to see closing speeds. When you see no relative movement regardless of distance make the correction early.
