Being the nonlinear function of attack angle , the hydrodynamic forces acting upon the submersible are determined by a towing tank test 作用于潜水器上的水动力系攻角的非线性函数，可用拖曳水池试验加以测定。
And a pair of flaps , mounted on the stern stabilizers , enables the vehicle dive or surface in a spiral form , thus ensuring the vehicle almost directly under the support ship 在潜水器的尾部稳定翼上装有一对小襟翼，它可使潜水器在上浮下潜时，在母船的正下方作螺旋状盘旋。
