An investigation was conducted on Carriage III at the David W. Taylor Naval Ship Research and Development Center to determine the motions and performance of a power-augmented, wing-in-ground-effect model with load alleviation devices. The effects of soft and bumpered endplates and a flexible flap were investigated for a range of velocities, thrust-to-weight ratios, and irregular wave sea states. Results show that the flexible flap can provide a smoother, softer ride for a thrust-to-weight ratio of 0.20, but at the expense of decreased average heave and increased average drag. Results also indicate a transport efficiency degradation from 23.18 to 10.06 with increase in sea state from 0 to 5 for the model without load alleviation. The results are inconclusive for the soft and bumpered endplates. (Author)
