The Bell D-292 was an American experimental helicopter developed by Bell Helicopters for the United States Army Advanced Composite Airframe Program (ACAP), as part of the studies involved in the Light Helicopter Experimental (LHX) program. It had a gross weight of 7525 lbs. The program was intended to demonstrate the advantageous application of advanced composite materials and structural design concepts on the airframe of military helicopters. The primary goal was to reduce the cost of production of the airframes, and reduce their weight by 17%-22% respectively. The airframe cost $185,458. Materials made up 28% of this cost, and labor expenses the remaining 72%.
