Description
Technical field
The utility model relates to a kind of air-breather, is specifically related to one supercavitating vehicle scale model test air-breather under water.
Background technology
Along with the quickening of immersed body movement velocity, the hydraulic pressure bearing on it can reduce on the contrary, is reduced to a certain degree once hydraulic pressure, and the water contacting with immersed body will be vaporized, and forms cavity.By certain technological means, " bubble " wrapped up whole navigation thing, form a kind of " gas coat ", just can make object navigate by water all the time in home built supercavity inside, thereby avoid to greatest extent the viscous resistance of water, Here it is so-called " supercavitating vehicle ".
Supercavitating vehicle can obtain very high underwater navigation speed, and scale model underwater navigation test is the important technology approach of such sail body flow dynamic characteristic of research.At present, forming ventilation supercavity has two kinds for the conventional air-breather of carrying out scale model test, and one is gas generator, and another kind is built-in compressed gas cylinder.The former belongs to priming system, design, processing, manufacture and use and all need professional unit to be responsible for, and transport, storage etc. exists safety problem.And built-in compressed gas cylinder external form is generally right cylinder, need sail body inside that enough spaces are provided, need special adapter (as rubber blanket etc.) to realize gas cylinder is connected with the reliable of sail body simultaneously, guarantee that sail body is stable, and then make whole sail body structure become complicated, and overall weight is larger, and can not effectively utilize sail body inner space.In addition, supercavitating vehicle aeration vent is positioned at front end, breather valve objectively requires to be arranged on front end for this reason, consider that supercavitating vehicle leading portion is generally tapered, be difficult to the space of the installation operation valve that provides enough, and when being arranged on front end, operation valve because controller is arranged in model rear deck section, there is the problem of operation valve signal wire cabling difficulty.Thereby above-mentioned two kinds of model test air-breathers are restricted to a great extent, be difficult for generally adopting.
Utility model content
The utility model is existing for carrying out gas generator formula air-breather existence transport, the storage poor stability of scale model test for solving, and built-in compression bottle formula air-breather exists and need to gas cylinder be connected with sail body special adapter, take sail body space large, whole sail body complex structure, large and the signal wire cabling difficulty of weight, the problem that use cost is high, and then one supercavitating vehicle scale model test air-breather is under water provided.
The utility model solves the problems of the technologies described above adopted technical scheme: one under water supercavitating vehicle scale model test comprises truncated cone-shaped cabin with air-breather, pipe core, wireway and solenoid valve, described truncated cone-shaped cabin is enclosure, in truncated cone-shaped cabin, be provided with a pipe core, one end of pipe core is packed on the minor diameter end face in truncated cone-shaped cabin and through this minor diameter end face, the other end of pipe core is packed on the major diameter end face in truncated cone-shaped cabin and through this major diameter end face, wireway is packed on the major diameter end face in truncated cone-shaped cabin, solenoid valve is arranged in the outside of the major diameter end face in truncated cone-shaped cabin, one end of wireway is stretched in truncated cone-shaped cabin, the air intake opening of solenoid valve and the other end of wireway be communicated with, the gas outlet of solenoid valve is communicated with the other end of pipe core, described truncated cone-shaped cabin is stainless steel cabin, pipe core is stainless-steel tube, wireway is stainless-steel tube.
The beneficial effects of the utility model are, the utility model is for sail body appearance structure, compressed gas cylinder and the gas generator of ventilation use are removed, optimize sail body cabin section, truncated cone-shaped cabin and existing sail body mock-up cabin segment structure are realized integrated, carry out truncated cone-shaped cabin (gas cylinder) external form and front and back Interface design according to sail body model structure characteristic, using sail body truncated cone-shaped cabin, (cone cabin section) structure itself is as gas cylinder, the gas cylinder while is as a part for sail body shell structure, vent line passes in the middle of gas cylinder, compared with built-in gas cylinder, do not need special adapter to be connected with sail body gas cylinder, take full advantage of space, in the identical situation of charge pressure, increase air storage amount, and sail body one-piece construction is simple, lightweight, weight has reduced 25%-35%.Truncated cone-shaped cabin, pipe core and wireway all adopt stainless steel material, and intensity is large, are conducive to meet underwater operation environment.AVSV Air Vent Solenoid Valve is arranged on the larger diameter end of truncated cone-shaped cabin section simultaneously, arrange and install easily, the length of the cable that the controller of arranging in the middle deck section of solenoid valve and existing sail body is connected significantly shortens, and easy to connect, saved cost, the use cost of cable has reduced by 2/3rds.Carry out yardstick according to likelihood principle and dwindle, this practical utility model is to carry out model contracting ratio according to 1:6 ratio, if utilize prototype test very high to place and cost requirement, scale model can be cost-saving, saves time.
The utility model solenoid valve is arranged on the larger diameter end of truncated cone-shaped cabin (gas cylinder), gas in gas cylinder enters solenoid valve by wireway, lead to truncated cone-shaped cabin smaller diameter end by solenoid valve through pipe core again, discharge in the gap that gas forms from cavitation device (smaller diameter end in truncated cone-shaped cabin be threaded cavitation device) and truncated cone-shaped cabin (being gas cylinder), forms supercavity.
