Educational Institution: Kolomensk branch of Moscow State Open University Project description: Water pump presented at competition is designed for cooling a ship engine with outboard water. Pump's frame belongs to the category of shell structures with a geometrically complicated space shape. Complicated shape and geometric dimensions of such frames are indented for creating required jets of gases and liquids. 3D assembly of the pump is parametric and carried out with a careful detailing. The elements of the T-FLEX CAD libraries were used as standard parts. In spite of the fact that the assembly consists of a moderate number of solid parts (115), many of them have spatial geometry.
