METHOD OF DETERMINING STABILITY FACTOR OF UNMANNED UNDERWATER VEHICLE BY EXPERIMENTAL MEANS Russian patent published in 2020 - IPC B63G8/14 

FIELD: underwater vehicles.

SUBSTANCE: invention relates to underwater equipment engineering, namely to methods of measuring stability coefficient of small unmanned underwater vehicles (UUV), which do not have active means for submersion into submerged position without travel. Prior to submarine immersing into submerged position, its on-board measuring equipment is switched on, then, to ensure UUV submersion into submerged position at fixed depth without travel floating buoy is used, to buoy turn of feeding end of UUV is movably connected at preset distance from float. Thereafter, the UUV is immersed into a submerged position at a fixed depth owing to the weight of the load of the floating buoy, held in a submerged position at a fixed depth, to stabilize the UUV position in the submerged position, owing to buoyancy of the float of the floating buoy. Then trim angle is measured Ψ₁. Thereafter, UUV is tilted by differentiation by outside action of body in fore end with weight of sinker creating inclining force and retaining UUV in this position to stabilize UUV in submerged position, and trim angle is measured. From values of trim angles Ψ₁ and Ψ₂ value of stability factor is calculated.

EFFECT: achieving the value of the UUV stability coefficient.
