A pneumatic-driven airdropped portable underwater profiler for rapid deployment

This paper puts forward a new underwater profiler. The mass of the whole machine is about 7Kg, with smaller volume. It can be air-dropped and suitable for fast deployment, as well as uses pneumatic method to adjust buoyancy, which is reliable with low cost, and can be used for a large scale of deployment. Its attitude can be adjusted throughout modulating barycenter, and with the assistance of wings, water power is utilized for path planning and achieve localized or larger range of supervision. The biggest dive depth is 1000m, in which situation 50 times' profile survey can be achieved, and it is suitable to be applied for emergent maritime search and rescue, etc.
