Description

technical field [0001] The present invention relates to a small propeller, in particular to an underwater booster. Background technique [0002] The underwater booster (dive propulsion vehicle, DPV), also called the frogman booster, is one of the important aids for navy frogmen or diving enthusiasts to carry out shallow sea diving, and it is more and more favored by users abroad; The underwater booster provides people with a new way of entertainment, it improves the range and speed of people's activities in the water, it not only allows people to navigate freely on the water surface, but also brings swimmers into the underwater world, Sightseeing, exploration and other activities are much more interesting and attractive to people than traditional entertainment activities. [0003] At present, underwater boosters are very popular in foreign countries and are becoming a common household entertainment tool; the underwater booster project can not only meet the needs of people's...

AI Technical Summary

Problems solved by technology

[0004] There are a large number of foreign manufacturers of underwater boosters, and the product categories are also very rich, such as AerisDPV, Torpedo DPV, SeaDoo and Oceanic Mako, etc.; while the production and development of domestic underwater boosters have just started, and manufacturers are very It is understood that the Kunming 750 Research Institute has imitated a type of Russian military underwater booster, and its performance indicators are not yet known; relevant domestic shipyards have also organized similar research, but failed because key technologies such as propulsion and sealing did not pass the test ; It can be seen that if the underwater booster is developed, once it is successful and mature, it will have a very broad market prospect
