Abstract

Static characteristics of an ACV (Air Cushion Vehicle) over irregular ground are investigated theoretically and experimentally. The exponential theory is developed for this purpose. Calculations are made for the case of two and three dimensional models, and the results are compared with experimental ones.<BR>Theoretical results show good agreement with those of experiments except the particular cases such as the hover height is very low, or the higher portions of ground roughness is close to the peripheral nozzle.<BR>The effects of the partition on lift and moment characteristics are also studied. Calculations show that partition equipped on the base affects the lift augmentation ratio especially at large d/D, but there exist little effects on experimental results. On the other hand, moment characteristics calculated agree with the measured values qualitatively.
