Deep sea manned submersible synchronous folding horizontal stabilizer

Abstract

The invention discloses a deepsea manned submersible synchronous folding horizontal stabilizer, which comprises a manned submersible body.A vertical stabilizer is arranged at the tail of the manned submersible body, horizontal stabilizersare symmetrically arranged at the two ends of the vertical stabilizer, the vertical stabilizer is of a fixed structure, and the horizontal stabilizersare of movable structures;open grooves are symmetrically formed in the tail of the manned submersible body, and the horizontal stabilizersextend and retract at the positions of the open grooves; the deepsea manned submersible synchronous folding horizontal stabilizer is compact and reasonable in structure and convenient in operation, and the retracting and extending of the two horizontal stabilizers are synchronously controlled through the telescopic movement of an oil cylinder. During floating and diving of a submersible, the horizontal stabilizersare retracted into the interior of the manned submersiblebody so as to reduce fluid resistance and increase the floating and diving speeds of the submersible. When the manned submersible dives to the bottom of the sea and sails,the horizontal stabilizers can be extended to ensure sailing stability of the manned submarine.

Description

technical field [0001] The invention relates to the technical field of manned submersibles, in particular to a synchronously folding horizontal stabilizing wing of a deep-sea manned submersible. Background technique [0002] Due to the limitation of the life support and oxygen supply capacity of deep-sea manned submersibles, the total time for a full-process operation is fixed. Therefore, the faster the diving and rising speed, the more time is left for the manned submersible to work underwater. The longer the submersible is, the higher the efficiency of the submersible is. Usually, deep-sea deep-sea manned submersibles have index requirements for the speed of diving and ascent. At present, most of the deep-sea manned submersibles in the world are to save power. All rely on the installed floating and diving ballast to realize the unpowered floating and diving movement of the submersible. In order to speed up the speed of diving and rising, researchers in the world mainly us...

AI Technical Summary

Problems solved by technology

In order to speed up the speed of diving and rising, researchers in the world mainly use two methods to achieve this. One is to reduce the fluid resistance of the manned submersible, and the other is to increase the weight of the ballast on the dive and rise. Realized, but the latter will directly lead to an increase in the total weight of the manned submersible, which is unfavorable for controlling the weight of the submersible, and it is very easy to cause the weight to exceed the index range

[0003] The tail of the manned submersible is usually equipped with a vertical stabilizer and a horizontal stabilizer to ensure the stability of the submersible. However, the horizontal stabilizer is extended outside the submersible. The fluid resistance generated by the horizontal stabilizer accounts for a large part of the total resistance of the submersible, which seriously affects the speed of the submersible's ascent and descent
