Abstract

The invention provides a device and a method for quickly adjusting the weight center of gravity of a ground-effect air cushion aircraft model, which can quickly and accurately adjust the weight center of gravity of the ground-effect air cushion aircraft model by utilizing a lever principle, and accurately test the movement stability and rapidity of the ground-effect air cushion aircraft model sliding on the water surface. And the actual mechanism type of the ground-effect air cushion aircraft is better optimized. The method is practical, feasible, simple to operate, reliable in test result and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of ground-effect air-cushion aircraft tests, and in particular relates to a device and method for quickly adjusting the center of gravity of a ground-effect air-cushion aircraft model. Background technique [0002] The ground-effect air-cushion vehicle is an aircraft that can slide, take off and land on land and water at the same time. The stability and rapidity of the ground-effect air-cushion aircraft directly affect its safety and economy in use when gliding on the water surface. The change of the weight size and the position of the center of gravity of the ground-effect air-cushion aircraft directly affects the adaptability of the air-cushion apron to the water surface. Therefore, compared with conventional ground-effect vehicles, the performance of ground-effect air-cushion vehicles when gliding on the water surface is more sensitive to changes in the weight of the load and the position of the center o...
