Summary:The invention provides a method for calculating responsivity of an apron air cushion system of a hovercraft. In the sailing process of the hovercraft, the height change delta hc of the air cushion iscaused by rising of the water surface or falling of a hull, firstly, it is assumed that apron deformation is delta hs0, and the air cushion pressure Pc and the bag pressure Pb are solved according toa draught fan characteristic curve and a draught fan-air duct-large bag-air cushion flow continuity equation; apron deformation is calculated to obtain actual apron deformation delta hs; the process is subjected to multiple rounds of iteration until the standard is met, and finally the obtained delta hs/delta hc can be used as the standard for measuring the responsivity of the apron of the hovercraft. In the hovercraft apron design process, responsivity calculation can guide apron design to improve the overall performance of the hovercraft. According to the numerical calculation method for theresponsivity of the apron
