This paper analyses the propulsion system of a 7000m manned submarine,offers a 6-dof thrust conversion model,and discusses its optimal control allocation problem in particular.
In this paper,according to the characteristics of a Human Occupied Vehicle(HOV) being developed by China and the requests for dynamic positioning,a method is presented to integrate LQR optimal control method with recursive identification method of parameters-Adaptive LQR.
This paper firstly described the selective principle of communication method, then proposed to realize the communication of the simulation system of human occupied vehicle based on TCP/IP sockets technology.
The paper steps from the national "project 863", focuses on hydrothermal vents image recognition, which is one of the items of 7000 meters manned underwater vehicles technology.
A new extremely thermophilic methane-producing bacterium was isolated from a submarine hydrothermal vent sample collected by a research team from the Woods Hole Oceanographic Institution using the manned submersible ALVIN.
Ultrastructural features of oogenesis were examined in the pelagic polychaetes Rhynchonerella angelini and Alciopa reynaudii which were collected from Bahamian waters by a manned submersible during 1979 and 1980.
caudata Desbruyères and Laubier, 1986) and their tubes were sampled from deep-sea hydrothermal vents at 13°N from the manned submersible "Nautile" during the "Hydronaut" cruise (October to November 1987) on the East Pacific Rise.
Behavioral observations in situ on Jeffreys Bank in 1986 were made using a manned submersible to observe the withdrawal and extension of specified sea pens.
The individual SCMs are linked to a common junction box by electro-optical cables, which are connected using a manned submarine.

This paper employs potential flow methed to calculate the wave forces acting on a manned submersible near the free-surf ace. The theoretical explanations are given that on condition of wave weather the submersible sailing on the surface is unabee to dive unless a negative bouyancy is added, and that at the periscope depth there will be suction effects and the submersible tends to be surfaced. This is of pratical significance for the analysis of the submersible hydrodynamic circumstance, and for the submersi...
In this paper, various Underwater Vehicles successfully manufactured by JAMSTEC, including Remotely Operated Vehicle(ROV), Human Occupied Vehicle(HOV) and Autonomous Underwater Vehicle(AUV), are introduced, and the role played by these underwater vehicles in deepsea topography, geology, and biological oceanography is mainly described.
DSV (Deep-sea submersible vehicle)-specific tool-box is irreplaceable in the deep-sea resources exploitative activities. Considering the tool-box as an indivisible part of the DSV is one of significant factor of DSV principle design, which means that the deep-sea resources exploitation will be one of most important activities for the coming DSV. Based on the investigation of DSV Alvin of Woods Hole Oceanographic Institution, the USA, underwater manipulators, sensors, sampling devices, and relevant technolog...
