Problems solved by technology

[0003] In order to study the hydrodynamic problems of transboundary aircraft entering and exiting water, Jilin University announced a measurement system for the water entry and exit motion data of the scale model of the trans-medium aircraft, but this system cannot measure the water entry and exit of the sea-air trans-media aircraft model The force data of the six degrees of freedom in the process, and these mechanical data are very critical, so it is necessary to design a special force measuring platform

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 ...

Abstract

The invention provides an in-water and out-of-water force measuring platform device and a testing method for a sea-air cross-medium aircraft. The in-water and out-of-water force measuring platform device comprises an integral base (1), a sliding module fixing frame (2), a speed regulating motor (3), a sliding module (4), a link structure (5), a sliding block (6), an adapter plate (7), a six-component balance (8), a manual angular position table (9), a supporting rod (10), a measuring carrier (11) and a water bucket (12). The integral base (1) is connected with the sliding module fixing frame (2); the sliding module (4) penetrates through the sliding module fixing frame (2) and is connected with the sliding module fixing frame (2); and the water bucket (12) is arranged below the in-water and out-of-water force measuring platform device for a sea-air cross-medium aircraft. An in-water and out-of-watertest system with variable initial speed, variable acceleration and variable attitude angle is put forward aiming at related requirements of sea-air cross-medium aircraft research, and measurement of key data can be realized.

Description

technical field [0001] The present invention relates to the design field of sea-air cross-medium equipment, in particular, to a water-entry and water-out force measuring platform device and test method for a sea-air cross-medium aircraft, especially to a variable initial speed, variable acceleration, variable Water exit and entry test system at attitude angle. Background technique [0002] Sea-air cross-media vehicles can not only navigate underwater, but also fly in the air, and can repeatedly cross the water-air interface. In recent years, it has become a research hotspot in the world. Since the sea-air cross-medium vehicle is not affected by the take-off distance across the medium, it has become an important research direction of the cross-medium ocean vehicle. Whether the structure of the vehicle will be damaged when the trans-media vehicle breaks through the free surface, whether the vehicle has motion stability, etc., are all issues that cannot be ignored, and these p...
