FIELD: transport.
SUBSTANCE: invention relates to transport machine building. Onboard hydrodynamic grill for amphibious tracklaying vehicle is intended for floating controllability improvement and is mounted near driving wheel. Hydrodynamic grill represents a set of vertical bended blades. To increase efficiency of reverse flow formed by top run the blades are installed in two rows. Top row of blades is located between track and over-crawler shelf. And over-crawler blades by their entrance segments are faced to reverse flow and have a curvature gradually increasing towards driving wheel: 
where i - serial number of blade (i=3-5); b - over-crawler shelf width; n - number of blades and installed with pitch of 
EFFECT: increase in amphibious tracklaying vehicle manoeuvrability is achieved.
