Abstract: (1111 Views)
Gliders are new marine vehicles which have research and military uses and they move by sequent diving and climbing. Suitable design of its main body and wings are important for the most advance velocity. hydrodynamic design variables are main body form, wings (cross section, dimensions, shape, longitudinal and vertical position) and hydrostatic parameters (static trim angle, amount of added force). Spray marine glider is selected as the initial design and changing each of its component in numerical simulation show its effects on the glider performance then the appropriate ones are chosen. The glider is simulated by computational fluid dynamics method in Star CCM+ that its error is less than 10% according to a validation. The main body of Spray has the least resistance force. Symmetry sections performance are better for the wings, and NACA 0012 foil is chosen. smaller wings are better. by moving the wings to back of the glider the advance velocity increases. Increasing the static trim angle and the added force causes increasing the advance velocity.
