New eight-bladed LC-130 propellers should provide more thrust at lower air speeds, helping lift the aircraft off the ice, as well as increase the climb rate and cruise speed, improve short-field performance and reduce noise and vibration. Compared to the four-blade propellers, which are very heavy and rectangular, the NP-2000 propellers are lighter and more aerodynamically shaped. The LC-130 airplanes are flown by the New York Air National Guard.
