Designing and manufacturing Bernoulli’s based water speed sensor for applied on Autonomous Underwater Vehicle
Speed estimation is one of the important parameters in navigation of an Autonomous Underwater Vehicle (AUV). Varied underwater speed sensors exist that they use of different technologies for measuring of an underwater speed. For example, ultrasonic, electromagnetic, optical and paddlewheel speed sensors and Doppler Velocity Log (DVL) are used for water speed measuring. The purpose of the article is designing and manufacturing of a differential pressure based speed sensor that measures an AUV speed by using of Bernoulli’s low. For analyzing of the proposed sensor, it is tested in the towing tank of the National Iranian Marin Laboratory (NIMALA). For determining of the sensor measurement accuracy, the sensor data is compared with an accurate speedometer that is installed on the towing tank. With analyzing of the results, the sensor accuracy is 0.05 (m/sec) in speed range 0.5-4.5 (m/sec).
