Problems solved by technology
This method is theoretically feasible, but in practical applications, the glider dives deep, and the use of motors to control the angle requires particularly high sealing performance of the motor itself, which is very unfavorable for the deep-water operation of the glider

Embodiment Construction
[0023] Such as figure 1 As shown, an underwater glider wing with an unsteady lift-drag ratio adjustment mechanism includes a wing 1, which is connected with an adjustment mechanism, and the adjustment mechanism includes a fixed bracket 2, a linkage part 3, and The oil passage control part 4, the linkage part 3 and the oil passage control part 4 are both installed on the fixed bracket 2, the oil passage control part 4 and the linkage part 3 cooperate with each other to form a passage through the oil passage control part 4 Control adjustable angle wing 1.
[0024] The oil passage control part 4 includes an upper oil bladder 41, a valve body controller 42 and a lower oil bladder 43. The upper oil bladder 41 and the downstream bladder 43 are respectively connected to two ends of the valve body controller 42;
[0025] The valve body controller 42 is provided with a solenoid valve 421, a high-pressure pump 422, and connecting pipes connecting the upper oil bag 41 and the lower oil bag 42...

The invention relates to the technical field of underwater glider wing adjustment, in particular to an underwater glider wing with an unsteady lift-drag ratio adjusting mechanism. The underwater glider wing comprises a wing body. The adjusting mechanism is connected to the wing body and comprises a fixing bracket, a linkage part and an oil way control part. The linkage part and the oil way control part are both installed on the fixing bracket. The wing body is connected with the linkage part, and the oil way control part and the linkage part are matched with each other, so that the wing of which the angle can be adjusted under the control of the oil way control part is formed. According to the underwater glider wing with the unsteady lift-drag ratio adjusting mechanism, the lift-drag ratio of the wing can be changed, accordingly, the component contributed by the glider wing buoyancy in the horizontal direction is improved at the maximum efficiency, then the cruising ability of a glider is improved, and the movement efficiency of the underwater glider is greatly improved, that is, the cruising mileage of the underwater glider is increased.
Description
Technical field [0001] The invention relates to the technical field of underwater glider wing adjustment, in particular to an underwater glider wing with an unsteady lift-drag ratio adjustment mechanism. Background technique [0002] At present, most of the existing traditional gliders at home and abroad use fixed wings, that is, the angle between the wing and the fuselage is relatively fixed; however, when the glider descends or floats, the lift generated during its motion mainly acts on the wings, and The lift-drag ratio of the wing is a fixed value, because at the same depth, when the glider moves from the highest to the lowest or from the lowest to the highest, the heading angle of the glider is relatively fixed, so the lift-to-drag ratio of the wing It is fixed, so the glide distance of the underwater glider is a fixed value. Therefore, without changing the glider mechanism or battery capacity, the underwater gliding distance of the glider is a fixed value, and the horizont...
