| By investigation of design theory of the air cushion vehicle on soft ground,the overall design plan was put forward and a model of the air-cushion vehicle was successfully produced.On the basis of theory analysis and experiments,the main structure and performance parameters were determined and the power balance equation was given.The power consumption of the generator was analysed.It proved that the design theory of air cushion vehicle on soft-ground was feasible by experiments on the pressure and flow rate of thefan and cushion lifting power under several working circumstances. |
