Embodiment Construction
[0041] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0042] The invention can realize the vertical water entry and vertical water exit tests of the real-scale sea-air cross-medium aircraft model at different initial velocities, different accelerations, and different attitude angles, and can analyze the initial speed and acceleration of the real-scale sea-air cross-medium aircraft model. , Attitude angle can be adjusted more precisely to meet the initial speed from 0m / s to 0.5m / s for entering and exiting the water, and the acceleration of 0.07m / s 2 ~1m / s ...
