Domes, Towed Bodies & Fairings
These sensor platforms provide a 360º acoustic window in the horizontal plane. Varying in size from 4.5 to 18 feet (1.37 to 5.49 meters) and made from steel or composite material, Indal Technologies towed bodies are acoustically transparent and provide a stable hydrodynamic platform for sonar operations.
The hydrodynamic design of Indal towed bodies minimizes drag and motion during towing.
Curtiss-Wright's Indal sonar domes are a double-skin design, offering strength, low weight, long life, low attenuation and low flow noise as well as reduced maintenance costs. The domes are functional in conditions up to sea state 9 and maximum ship speeds. An electromechanical hoist allows the transducer to be raised into the ship for maintenance and protection, and lowered into the dome for sonar operations.
Fairings and Cables
One of the key components of any towing system is the tow cable. Reducing drag is critical to attaining the maximum possible depth at minimum cable length.
For applications when speed and depth are crucial, the Indal Flexnose fairings have a demonstrated record of high performance. Flexnose fairings are the lowest drag coefficient fairings commercially available, and are used by numerous navies and leading oceanographic institutions and companies.
Curtiss-Wright engineers and manufactures a range of naval mine-countermeasures products, including versatile mine hunting sonar launch and recovery handling systems as well as remotely operated vehicles are key components of many mine-countermeasures programs.
