The invention discloses a wind wing device for fixed-height parachute opening of an aviation sonar buoy, and relates to the technical field of aviation sonar buoys, the wind wing device comprises a wind wing, a foldable empennage and a height control assembly, and the wind wing device is assembled at the top of the sonar buoy in a foldable mode and then is filled into a buoy throwing cylinder. After the sonar buoy is ejected out of the cabin from the throwing cylinder at the high altitude, the wind wing device does not break away immediately, the cross-shaped empennage extends out of the top, the sonar buoy descends along the trajectory, after the sonar buoy reaches the preset height, the wind wing device breaks away automatically, the buoy parachute is pulled out, and the sonar buoy descends in a decelerated mode and falls into the sea after the speed is stable. The airborne landing process of the sonar buoy can be divided into a front section and a rear section, the front section descends in a middle-high altitude in a ballistic trajectory mode, the rear section descends after low-altitude deceleration, and the anti-submarine aircraft can have the capability of accurately distributing the sonar buoy under the high-altitude high-speed flight condition. The device is simple in structure, small in size, light in weight, low in cost and easy to implement.
本专利公开了一种用于航空声呐浮标定高度开伞的风翼装置,涉及航空声呐浮标技术领域,包括风翼、可折叠尾翼和高度控制组件,可折叠装配在声呐浮标顶部,然后装填进浮标投放筒。待声呐浮标在高空从投放筒弹射出舱外后,风翼装置并不立即脱离,而是在顶部伸展出十字尾翼,使声呐浮标沿弹道轨迹下降,到达预定高度后,风翼装置自动脱离,拉出浮标降落伞,使声呐浮标减速下降,速度稳定后落入海中。利用本发明可将声呐浮标的空降过程分为前后两段,前一段是在中高空保持弹道轨迹下降,后一段是在低空减速后下降,可以使反潜机具备高空高速飞行条件下精确布放声呐浮标的能力。本发明结构简单,体积小,重量轻,成本低廉,易于实现。
