U.S. Army AH-64D Apache Helicopter

[1996] Dr. Earl Duque of the Rotorcraft CFD Group of the U.S. Army Aeroflightdynamics Directorate at NASA's Ames Research Center created, using Gridgen, these surface grids for the U.S. Army's AH-64D Apache helicopter. The surface grids were then used as the basis for a grid of overlapping blocks on which the flowfield was computed.
