The invention relates to a multifunctional small acceleration casting track, and belongs to the technical field of aerospace structure water entry impact and airplane water forced landing. The problems that in the prior art, the water contact position of a measured object is not easy to control within an observable range, casting is far, the length of a water tank is insufficient, and various working conditions of a casting experiment and a forced water entry impact experiment are difficult to meet are solved. Through the linear bearing on the fixed platform, the position of the device on the water tank is adjusted, and the water touching position of the model can be controlled within an observable range; through the linear electric cylinder, the initial height from the model to the liquid level when the model is thrown out is adjusted by adjusting the height of the sliding rail, and the needed water area length is effectively controlled; the angle between the sliding rail and the liquid level is controlled by rotating the actuator, and the speed components in the vertical direction and the horizontal direction can be controlled by adjusting the angle between the sliding rail and the liquid level. Or the sliding rail is adjusted to be perpendicular to the liquid level, and then the sliding block drives the measured object to move downwards to impact the liquid level.
本发明涉及一种多功能小型加速抛射轨道,属于航空航天结构入水冲击以及飞机水上迫降技术领域,解决了现有技术中被测物的触水位置不易控制在可观测范围内、抛射较远而水槽长度不足和难以满足抛射实验、强迫入水冲击实验的各种工况的问题。本发明通过固定平台上的直线轴承,实现调整设备在水槽上的位置,可以将模型触水的位置控制在可观测范围内;通过直线电动缸,通过调整滑轨的高度,进而调整模型抛出时距液面的初始高度,有效控制所需水域长度;通过旋转执行器,控制滑轨与液面之间的角度,通过调整滑轨与液面的角度,可以实现对垂向、水平两个方向速度分量的控制;或将滑轨调整至与液面垂直,之后滑块带动被测物向下运动撞击液面。
