| Summary: | An experimental hovercraft has been developed for tests on the utility, adaptability and operation of hovercraft in the environment of the Antarctic. The Hovercraft Subcommittee formed in 1978 has been managing the planning of this project. The craft is a 2.8t plenum chamber type hovercraft with 60cm depth flexible skirts, fitted to its perimeter. Two rudders equipped within the air jet bleeded from the lift fan, and two puff ports which control the air jet, provide directional control. In order to estimate the performance of the craft, the static thrusts were measured. In January 1981,the craft was unloaded on the fast ice about 40km NW of Syowa Station in the Antarctic. After 3.5 hours run it reached the station, crossing small cracks and puddles. During the summer and winter seasons of 1981/82,33 hours test running and sea-ice survey have been carried out. Some troubles such as the clogging of snow in the engine room, icing on the air outlet from fan scroll and tear of skirts were experienced. The process of planning, design, principal particulars, slope ascending capability and the operation in the Antarctic of the experimental hovercraft are described. |
