Tiltable sonar head

Postby henning_føsker » Fri Apr 01, 2005 3:43 am

When using VideoRay for inspection in confined spaces as tunnels, shafts, pipes, intakes etc. the sonar is essential. In its normal mode of operation (vertical axis) it creates a horizontal (plan) section of the space. As essential as plan section is a cross section or a longitudinal section, e.g of a tunnel. This is achieved with the sonar head axis horizontal. In stead of pulling the sub out of water to tilt the head, I have made it tiltable by applying RC-model aircraft techology to the sub. The manip is used as servomotor and the linear movement is transferred via rods and bellcrank to a moulded, hinged cradle in which the head is mounted. Materials are Graupner carbonfiber rods and ball joints (unfortunat balls are carbon steel and they corrode!), aluminium bellcrank and carbonfiber/epoxy cradle.
