Topic:R&D and Application Progress of Marine Towed System Technology
Lecturer:Yanfeng Wang
About the Lecturer:Dr. Yanfeng Wang, a researcher who has been working on the R&D of marine monitoring technology and marine observation, studies the R&D and application of marine towed system, R&D of marine optical instrument and sea-air interface observation, etc. Wang has hosted National High-tech R&D Program (863 Program), the Natural Science Foundation of China Programs, and Marine Public Industry Research Project, and he has published more than 40 papers and has many patents with 2 provincial and ministerial-level Second Awards and 3 Third Awards. Wang is now a member of the council of Meteorological Hydrological and Marine Instrument under China Instrument and Control Society, and a member of Marine Physics Branch of Chinese Society for Oceanography.
About the Lecture:This lecture will introduce the development of the CZT Towed System, which integrates multidisciplinary sensors, observing many factors including temperature, salinity, pressure, chlorophyll A, turbidity, dissolved oxygen, and pH. In order to ensure the accuracy and the depth of observation, the towed system should have a good hydrodynamic performance, a smooth water exchange channel, a fast response capability and a high precision measurement performance of the sensor. (1) In the overall design, the control wing is used to control the profile depth of the central point rotation of the hydrodynamic center, the towing cable adopts a flexible and low resistance guide sleeve. The three points above optimize the hydrodynamic performance of the towed system. (2) On the basis of establishing a complete hydrodynamic model of towed system, the lift and drag characteristics of the control wing are analyzed, and the shape of the control wing is optimized. (3) Through the Lake Test and sea test, the system design is improved, the performance of the system is verified, and a high-precision multi-factor synchronous observation section is completed, especially the cable depth ratio reached 1.2-1.5, indicating that it has excellent hydrodynamic performance. The results of small scale phenomenon observation confirmed the technical advantages of the towing system.
